Integrity Matters Now More Than Ever: Our Promise

grunbergerusa · June 8, 2020 · Leave a Comment

The public health crisis has shaken up the diamond industry, exposing vulnerabilities in global supply chain networks. And in a market where reputation means everything, you can’t risk any missteps in quality control and service.

With Grunberger Diamonds, you can be rest assured knowing you’ll always receive the best: always new; always natural; always brilliant.

From sourcing the rough ourselves to operating our own production facilities, we control all aspects of our supply chain — guaranteeing that every single diamond conforms to the highest cut criteria. It’s a promise we’ve kept since 1945.

Our rough diamonds come exclusively from a select group of suppliers we’ve had relationships with for decades. This helps us know exactly what we are buying, significantly reducing any chance that foreign or unnatural goods will find their way into our inventory. But this is not our only safeguard against synthetics. Because of our diamonds’ unique cut, it would be virtually impossible for synthetic diamonds to find their way into our inventory and not be spotted in the sorting process.

Of course, as certain as we are that these safeguards will prevent synthetics from ever entering our inventory, we do understand that nothing is better than peace of mind and extra assurance.

Back at our headquarters in Antwerp, Belgium, every diamond goes through the M-Screen+, a state-of-the-art machine that screens, sorts, and singles out stones that might be synthetic.

Learn more about Grunberger Diamonds’ M-Screen+.

Last year, we achieved Responsible Jewellery Council (RJC) Certification by meeting the highest ethical, social, and environmental standards set forth by the international nonprofit. Being a RJC member reinforces our unwavering commitment to human rights and ethical business practices.

At Grunberger Diamonds, your reputation means everything.During these trying and uncertain times, we are committed to providing you peace of mind, as well as the consistency and expert craftsmanship our clients have relied on for the last 75 years.

Here’s how to get in touch.

How COVID-19 Has Changed the Way You Buy Melee Diamonds

grunbergerusa · May 7, 2020 · Leave a Comment

While the full reach and impact of COVID-19 has yet to become clear, the pandemic has had a significant impact on the diamond industry as a whole. These challenges come from two directions. There’s been a dramatic drop in consumer demand, due to the economic uncertainty associated with stay at home orders. Second, the pandemic has caused supply chain interruptions worldwide, most especially in China, India and Israel.

What does this mean to the jewelry manufacturer and retailer, particularly as it applies to melee diamonds?

The first point we’d like to address is supply chain stability. While the pandemic is certainly unique, it’s not the first challenging time Grunberger Diamonds has been through. We have offices all around the world and have procedures in place to ensure that you can get our exceptional Ideal Cut melee diamonds in the quality and quantities you require. Whether you need to create a single stunning engagement ring or do an entire production run, we’ve got you covered.

During times like these, cash flow can be a challenge. Many manufacturers and custom jewelers prefer not to hold as much melee diamond inventory as they may otherwise choose to.  However, it’s also important to be able to respond quickly to customer requests. Being put on pause has not made anyone more patient. For that reason, we are currently shipping all orders within 2 business days so you can say yes to short deadline projects.

Here’s how to get in touch.

Times are Tough. Love is Tougher. Always.

Four generations ago, when Grunberger Diamonds was just getting started, the war was ending, and the future was uncertain.
People still got married.

Three generations ago, nuclear cataclysm seemed imminent.
People still got married.

Two generations ago, a disease no one understood & everyone feared emerged.
People still got married.

One generation ago, hurricanes, earthquakes and tsunamis wreaked havoc.
People still got married.

And here we are today. We don’t have to explain the situation to you: you know. The globe’s united in this latest challenge. We all share the same fear. No one knows what is going to happen. People will still get married.


People will still get married because they know that the only thing we can count on in this world is the power of love.

Faced with fears that aren’t the same – yet aren’t entirely different – than the ones our parents, grandparents, and great-grandparents faced; we’re going to react much the same way they did. We all want a hand to hold. No one wants to face the world alone.

Maybe that’s really why diamonds are ideal for wedding jewelry. Yes, they’re beautiful, yes, they’re precious, but when we get into what the defining quality of a diamond is – the factor that sets it head and shoulders above every other gemstone – it’s the diamond’s toughness. Created by intense crushing pressure, diamonds are strong enough to endure just about anything.

Just like love.

When we started Grunberger Diamonds, the circumstances of the time demanded that we be flexible and work with jewelry manufacturers and retailers so everyone could stay in business. And truth be told, that’s been the case ever since – we’re a global company, and as we all know, trouble travels everywhere. Someone’s always facing difficulties, but we’ve always been able to find a way to make it work.

And that’s what we’re going to do now. Grunberger Diamonds is absolutely committed to helping you create beautiful jewelry for your customers’ most special moments. That means no minimum order requirement on our ideal cut melee diamonds. While New York is under strict regulation and we will have a slightly longer turnaround than usual, we are still able to fill orders within 3 business days. If you need help making it happen, please, call us. Flexibility and understanding have been the key to our longevity, and we’re confident they’ll be the key to everyone’s future.

Hang in there. Love really does conquer all.

The Fashion World Is Fast. Grunberger Diamonds Makes You Faster.

grunbergerusa · March 12, 2020 · Leave a Comment

When the Fast Fashion phenomenon began, there were many who said it wasn’t relevant to the fine jewelry industry. Clothing can be produced very rapidly; the same is true for footwear and accessories. Jewelry operates on a different, slower timeline.

The only problem with this proposition is the immediate nature of customer demand. They want what they want, and they want it now. The manufacturing jeweler who can best help their brand and retail customers satisfy trend-driven demand is one who can produce superior product quickly, at a price point that makes sense.

The Impact of Melee Diamond Selection on Speed to Market

It’s important to consider melee diamonds from a variety of perspectives. For the moment, let us set aside the aesthetic considerations and focus on how melee diamond selection can impact your facility’s workflow.

The work begins when you open the parcel – are the stones you’re looking at what you expected in terms of quality, size, and cut? At some point, each of these diamonds is going to be subject to a customer’s scrutiny. That’s why you have your own internal quality review processes – and because you do, you know that there are some vendors who provide product that takes longer to use confidently than others. If you want to save time at this point in the process, it’s a good idea to buy from a vendor with a proven track record for consistently providing high quality, high precision melee diamonds.

Once the diamonds have been accepted and put into production, the value of high precision becomes clear. While every design has some tolerance built in, having stones that are the exact right size makes meeting production objectives easier and faster. This is especially relevant if some portion your work force is still developing their skills.

A final factor to consider is how long it takes to get the melee diamonds you need when you need them. Because Grunberger Diamonds has facilities all around the world, we same-day ship. This speed is critical to enabling you to be agile and responsive to your clients’ needs in the demanding age of Fast Fashion.

Is Fast Fashion here to stay? Who can say? Fast Fashion is here now, and there are opportunities for the jewelry manufacturers who can produce great products on an accelerated timeline. We’re here to help you make it happen. To learn more about our Ideal Cut Melee Diamonds, including pricing information, please fill out the form below.

Boost Your Custom Jewelry Profits: Which Melee Diamonds Offer the Best Count per Carat?

grunbergerusa · March 5, 2020 · Leave a Comment

Creating custom jewelry is a design challenge, requiring artistry and craftsmanship. Pricing custom jewelry – as well as your own showcase inventory – to maximize profitability while still appealing to your market is a business challenge, requiring a smart, strategic approach to product sourcing.

It’s a balancing act. You expect your customers to pay up for your merchandise, because you offer a superior product. The quality must be there, as does the eye-catching beauty. Customers don’t buy jewelry they don’t notice. That’s why when you’re choosing melee diamonds for your design, it’s important to select for brilliance. The Grunberger Precision Cut establishes maximum fire and brilliance in a diamond.

Another criterion is financial. Again, the Grunberger Precision Cut offers retailers a way to boost their profitability. Our Ideal Cut Melee Diamonds are lighter than other, less precise melee diamonds. This means you enjoy a better count per carat when you choose Grunberger Diamonds.

Try Grunberger Diamonds for Yourself

If you haven’t tried our Ideal Cut Melee Diamonds, we’d like to invite you to see what a difference high precision makes. We have no minimum order size and will make stones available on memo to qualified retailers. There’s nothing like seeing our product in person to convince you it’s right for your best customers – and once you’ve actually been able to work with our melee diamonds and discover what a pleasure it is to seat stones that are always exactly the right size, we think you’ll be very glad our diamonds are very competitively priced.

A Note About Where Grunberger Diamonds Come From

The retail customer is increasingly concerned about the materials used in their jewelry. Grunberger Diamonds is committed to meeting the highest ethical and environmental standards. We maintain end-to-end control of our product, sourcing our own rough, maintaining our own facility, and offering our product exclusively and directly to the trade. Learn more about our transparency & traceability processes.
