A Legacy Of Ideal Cut Diamonds

The Best Place To Buy Loose Diamonds

Our Grunberger Precision Cut® has the proportions needed for ideal cut melee diamonds, and boasts the most brilliance and best light performance. Due to our superior optical symmetry, our loose diamonds feature the faceted pattern known as Hearts & Arrows. We follow the highest level of grading standards and business ethics through the guidelines of AGS 0.

We created the Grunberger Precision Cut® with the desire to bring out the best in what ideal cut diamonds have to offer. Only through years of in-depth research, were we able to discover the perfect method of creating maximum fire and brilliance for every single diamond.

Achieving perfection, especially in melee sizes, is no easy task for a melee diamonds supplier. That is why we choose to specialize in a particular type of diamond and diamond cut – melee diamonds with Hearts and Arrows. Not only are our loose diamonds perfectly cut, but you also enjoy the unparalleled beauty only found with Grunberger craftsmanship.

The Grunberger Service Experience

We understand everyone has unique needs; that’s why we don’t set a minimum order requirement and can ship the same-day when you buy real diamonds with Grunberger.

Right from the beginning of your order, we ensure customer satisfaction by having our experts hand-pick the best diamonds straight from our factory based on size, color, and clarity and cut them based on your desired order.

To guarantee the perfect diamond every time, we calibrate each one to within 0.025mm of perfection before sifting them into even more specific sizes with our precision tool. A polished diamond never leaves our facility until it is closely inspected for imperfections and to ensure each diamond meets our strict Hearts and Arrows pattern guidelines.

With more than 75 years of excellence that has been passed down through three generations of Belgian cutters, we are able to maintain stellar consistency in our ideal cut melee diamonds. From our cutting facility in Vietnam to our headquarters in Belgium, every diamond goes through a strict sorting and quality control process before reaching our sales offices, where customers make their final selection.

Such care and detail is what makes Grunberger Diamonds the most prestigious melee diamond supplier in the world.
