Hearts and Arrows Diamonds: What Are the Benefits?

Daniel Grunberger · May 27, 2022 · Leave a Comment

Many people are familiar with hearts and arrows diamonds, but they might not know why these types of diamonds are so revered, or what makes them such a smart choice when purchasing diamond jewelry.

A popular style known for showcasing 3D optical precision, the hearts and arrows diamond represents superior craftsmanship and quality. But, there are many who may be unaware of why this particular cut is so lauded. Below, we’ll discuss what you should know about hearts and arrows diamonds, including what the term means and the various benefits this diamond can provide.

What Does Hearts and Arrows Mean in a Diamond?

A hearts and arrows cut features a round diamond with a facet pattern, including eight hearts (visible from the down-facing view) and eight arrows (visible from the table-up view). 

These diamonds, once known as hearts and cupids diamonds, originated in Japan. And, it is gemologist Kazumi Okuda who we have to thank for allowing us to see the hearts and diamonds pattern up close. In the 1970s, Okuda invented a tool called a Firescope, which uses colored reflectors to expertly highlight distinctions in the facet and light patterns of a hearts and arrows diamond.

Notably, it is a common misconception in the jewelry industry that if a diamond has hearts and arrows it is ideal cut. While many of these particular diamonds are ideal cut—including all of the diamonds that we sell—it is not always a given. To help our buyers showcase the brilliance of ideal cut hearts and arrows diamonds, we supply a hearts and arrows scope that lets customers see the precision-cut facet up close and verify that what they’re purchasing is a true ideal cut stone.

Hearts and Arrows Diamond: Worth It?

There are many reasons to opt for the hearts and arrow facet on a diamond. Here are some of the benefits of the cut, all of which make it a worthwhile purchase and investment piece.

  • Enhanced light performance – The ideal cut hearts and arrows pattern is completely symmetrical, optimal for light reflectivity and results in an inherently more brilliant diamond.
  • Optical precision – A hearts and arrows diamond offers optical precision, meaning it has complete surface consistency in terms of facet shape, size, and alignment. This level of precision is only found on the highest quality diamonds, and takes an immense amount of skill to create.
  • Bolder, more vibrant sparkle – Symmetry and precision in the design creates a stone unmatched in terms of sparkle. The result is an eye-catching diamond that stands out in any piece, one that will maintain its brilliance for many years to come.

When a hearts and arrows diamond is also ideal cut, it offers all of the 4Cs of an exceptional diamond: cut, color, clarity, and carat. For that reason, it’s essential to only buy an ideal cut hearts and arrows diamond, since otherwise you’re losing out on a lot of the potential beauty and value.

Diamonds with an ideal cut hearts and arrows pattern take more skill and more time to produce. However, when quality, brilliance, and longevity are the goal, it’s hard to do any better than a hearts and arrows stone.

What is Diamond Transparency and Traceability—and Why Does It Matter?

Daniel Grunberger · April 1, 2022 · Leave a Comment

There are a lot of factors that go into producing a great diamond, and while looks are obviously important, diamond transparency and traceability are just as crucial.

The diamond industry has a long and storied history, and unfortunately it hasn’t always been known for ethical practices. Consumers however want to know where the diamonds they are purchasing came from and how they were sourced. Jewelers who cannot answer these questions—or who cannot answer them in a satisfactory way—are going to lose these valued customers to those who can provide answers.

Here’s what you should know about transparency and traceability in the diamond industry, including why it’s an essential consideration to keep in mind when you purchase diamonds for your jewelry business.

The Importance of Working with Ethical Diamond Companies

At Grunberger Diamonds, ethics have always been a top concern. We provide melee diamonds for sale that come from areas where ethical sourcing is of the utmost importance. This means that we don’t source our diamonds from places like Russia where civil and environmental rights violations are par for the course, and that we provide our buyers with eco-friendly diamonds delivered on time, with the right specifications, and at a great price.

We are proud members of the Responsible Jewelry Council, which has established standards that promote better, fairer jewelry sourcing practices. As RJC members, we are accountable to the council’s codes of conduct, and have made a commitment to sourcing diamonds in a sustainable manner. This ensures that our buyers can get what they need without violating their own principles or the principles of their clientele.

Diamond Traceability and Transparency in a Changing World

Even the most beautiful of diamonds can have a backstory that is less than pretty. This may include human rights violations or violence against the environment. It may also mean sourcing from countries where these practices are accepted both within the diamond industry and outside of it.

Traceability is a way for buyers and their clients to know how each diamond got from earth to store, and answers a number of key questions that matter for diamond ethics. This includes:

  • Where diamonds were mined
  • How diamonds were transported
  • How far the diamonds traveled
  • How the diamonds were evaluated for quality

By getting more insight into the supply chain, buyers are able to trace the journey of their diamonds and pass that knowledge onto their customers. They also get transparency into the sourcing process and peace of mind that they are not supporting manufacturers or an industry that is contributing to abuses of humans, animals, or the planet.

Today’s jewelry buyers are more informed than ever about the impact of the industry, and they have high expectations when it comes to who they buy from. By prioritizing traceability and transparency, you help bridge the informational gap and give your customers confidence in their jewelry purchases. You also do your own part to support a diamond industry that’s rooted in ethics and sustainability—and that helps ensure eco-conscious diamond mining for many generations to come.

Do You Know Where Your Diamonds Come From?

Jewelers who partner with ethical diamond companies help amplify the importance of diamond transparency and traceability, raising the standards for the industry and providing their customers with pieces they can love for all the right reasons.

Grunberger Diamonds is a leading diamond manufacturer and supplier, and we offer ethically-sourced melee diamonds with the highest level of quality and precision to business owners in the jewelry industry.

Why Should Jewelers Care About Ideal Cut Melee Diamonds?

Daniel Grunberger · March 9, 2022 · Leave a Comment

In the world of jewelry, melee diamonds are proof that the size of a stone doesn’t count for everything when determining the quality of a piece.

Melee diamonds are one of the most popular types of diamonds that a jeweler works with, even if they don’t always get the same focus as the larger centerpiece stones. Despite their smaller size however, it’s essential that they’re ideal cut, with perfect ratios that highlight their beauty and lend extra sparkle to the piece at large.

So, what are melee diamonds and why is their cut so important? Here’s what all jewelers—and all jewelry buyers—need to know.

What are Melee Diamonds?

Melee diamonds are tiny diamonds sized anywhere from 0.001 carats to 0.2 carats. They’re often used as ornamental stones around a centerpiece diamond or other gemstone, or as the primary stones encircling an infinity band. You’ll often find melee diamonds encircling larger diamonds as part of halo and channel settings.

Although they’re the smallest diamonds that you can buy, melee diamonds undergo the same cutting process as larger stones. In fact, a melee diamond is similar in all ways to a larger diamond, with the number of carats serving as the only difference. As such, jewelers need to make sure that their melee diamonds are produced with an ideal cut, just as they do for their large diamonds. Failure to do so will result in melee diamonds that are lacking in sparkle and shine, and can greatly reduce the overall quality and value of a piece.

Ideal Cut Diamonds of All Sizes

All diamonds have four main features: cut, carats, color, and clarity. Melee diamonds, which are small in carats, still must excel in cut, color, and clarity in order to be of the highest quality. Jewelers who recognize this make sure that their customers are getting the very best piece for the price that they’re paying—and that these ornamental stones stand out for all of the right reasons.

Melee diamonds can be single cut (17 to 18 facets) or full cut (57 to 58 facets). And like any other size and shape of diamond, they can also be ideal cut, meaning they’re cut with perfect precision to achieve just the right angles for maximum sparkle. When we talk about the best melee diamonds, we’re almost always referring to ideal, full cut diamonds that are crafted with all of the proportional accuracy that we expect out of larger stones.

A diamond is an investment, regardless of its size. Therefore, jewelers who want the best for their customers understand the importance of ideal cut melee diamonds, and go above and beyond to ensure that every single stone is worthy of inclusion on a piece.

What Makes a Diamond Sparkle? Everything You Need to Know

Daniel Grunberger · January 21, 2022 · Leave a Comment

Whether you’re a novice or an expert in gemology, people love knowing what makes a diamond sparkle—and determining whether or not that sparkle is real, or fake. Diamonds are the most sought after gem on earth, and nothing is quite as brilliant as their shine. However, achieving this brilliance is entirely dependent on the cut itself, and a gem that elegantly reflects light is a sure sign of expert craftsmanship. Still, with the amount of synthetic and faux diamonds floating around the market, which can often look the part as the real thing, it’s always the right move to take it a step further, and know the signs between a real diamond sparkle vs. a fake one.

Real Diamond Sparkle vs. Fake

To properly analyze the difference between a real diamond sparkle vs. a fake, let’s start with a little bit of science. What makes a diamond sparkle comes down to the cut, and the way a beam of light reflects off of a gem. When a beam of light hits a diamond, its speed slows down significantly more than in the air, and this difference of speed bends the light into various rainbows of color and streaks of brilliance. The sparkle you see when looking at a diamond is merely a reflection of this light, and those dark spots you see… well chances are that’s your own reflection blocking some of the light. So, how do we tell the difference?

Perhaps the easiest way to determine a real diamond sparkle vs. a fake is to have it surveyed by an expert, who should easily be able to tell the difference. However, many at-home diamond sparkle tests exist to help you determine the legitimacy of a gem without the need for professional help. These tests can be completed with minor inconvenience and at little cost, and most of the time are extremely accurate if performed correctly. Some of these tests include:

  • Diamond Sparkle Test – The way a stone reflects and refracts light is a good indication of its authenticity. Since this natural light refraction cannot be altered, you should look for shades of gray in your sparkle analysis. If your stone is reflecting an array of iridescent colors, it most likely is synthetic.
  • Sandpaper Test – For this test, simply rub the gritty side of a piece of sandpaper against the stone in question. Since diamonds are one of the world’s hardest materials, a real diamond will not be affected by this scratching. However, a fake diamond will show signs of wear.
  • Read-through Test – This is a simple test that only calls for a piece of paper with readable black text. To perform, turn your stone upside down, and look through the upturned diamond to attempt to read the words. If the diamond is real, it will be impossible to see or read any of the text. If it’s fake, you will be able to make out the words to some extent, or read it completely.
  • Water Test – All you need to do is here is place your diamond in a cup of water. If it sinks, it’s real, as diamonds have an incredibly high density. If it floats either at the top or somewhere in the middle, it very likely is fake.

What Diamond Cut Sparkles the Most?

The various types of diamond cuts have a large role to play in how well a diamond sparkles, and even the slightest difference in cut can bring massive changes to the shine and elegance. Two of the main cut styles that produce this sparkle include brilliant cut and step cut. A brilliant cut is where angular facets radiate out from a center point, and will most of the time be more sparkly than their counterpart. Step cuts, which have long, rectangular facets arranged in a square or rectangular fashion, have a more subtle, sophisticated flash. 

Hearts and Arrows diamonds also have a particularly brilliant shine. For this diamond cut, it has a particular cut pattern of faceting that you can see reflected in a diamond’s light return with a special scope, appearing in the shapes of hearts and arrows. These are among the most difficult cuts to achieve, and truly create a brilliant sparkle often unmatched with others.

Is Diamond Fluorescence Good or Bad? What Is It and How Important Is This Quality?

Daniel Grunberger · November 4, 2021 · Leave a Comment

Diamond fluorescence – good or bad? This might be a question you’re asking yourself if you’re in the market to buy a piece of diamond jewelry. A diamond’s fluorescence can affect many important elements, including its price, market value, and appearance. It is almost certainly a quality that you’ll want to consider when buying a diamond. Understanding and knowing how a certain diamond’s fluorescence will affect your purchasing experience can help ensure you’re getting a fair price, that the diamond has good value, and that it will hold its value for years to come. 

What is Diamond Fluorescence?

Genuine, high-quality diamonds are an expensive investment, but they can prove quite valuable even years from now if you maintain their health with good, consistent care. However, fluorescent properties can significantly affect this investment, and its longevity. 

You will know if a diamond has fluorescence if it emits a blue glow while under a UV light (commonly referred to as a black light). Fluorescence is caused by trace elements that are found in naturally formed diamonds during the crystallization process. 

About one-third of all gem-quality diamonds have fluorescence, yet only about 1% of diamonds are visually affected. In order to determine whether or not a diamond is fluorescent, it will have to undergo the black light diamond test.

Once a diamond is exposed to black light, it will be measured on the diamond fluorescence scale. There are five levels in this scale:

  1. None

A diamond with no fluorescence will not emit a blue glow under the black light diamond test. Diamonds with zero fluorescence are considered to be the most valuable, desired, and expensive.

  1. Faint

Underneath a black light, diamonds with Faint fluorescence emit a very soft blue glow. The amount of trace minerals in these diamonds is so minimal that it will not affect the quality or value of the diamond. Diamonds that rank Faint and None of the fluorescence scale are considered to be of the same quality.

  1. Medium

Medium fluorescent diamonds emit a light blue glow underneath black light. The blue color that these diamonds emit can complement low-grade diamonds that appear to be a bit yellow, making them more valuable than they would be without fluorescence.

  1. Strong

Diamonds with Strong fluorescence emit a deep, blue glow underneath black light. The value of low-grade diamonds with Strong fluorescence can be improved with Strong fluorescence, as it will balance the yellow tint, but it can decrease the value of premium diamonds, as they may appear cloudy.

  1. Very Strong

Diamonds with Very Strong fluorescence emit a bright blue glow underneath black light. Very Strong fluorescence will make most diamonds appear cloudy and significantly decrease their price, value, and desirability.

How Important Is Fluorescence In A Diamond?

Whether fluorescence in a diamond is good or bad will be up to you, or the one you are buying the diamond for. Some individuals find “Very Strong” fluorescence a novelty quality, which could make that gift extremely valuable to them, even though the market might not agree.

In addition, you will have to take your budget into consideration. If buying a genuine diamond is of utmost importance to you, but you would like to avoid spending a fortune, a lower-grade, fluorescent diamond could be perfectly suited for you.

On the other hand, you may want to avoid diamonds that glow under black light if you know the person wearing them would find that unappealing. As we all know, beauty is in the eye of the beholder.

When it comes to finding the perfect diamond, we can tailor our customer’s orders to their exact specifications. We have many customers that want us to take out all of the fluorescence, and some customers that prefer us to take out just the strong fluorescence.
