Premium Branded Diamonds

In 1919 a young mathematician, Marcel Tolkowsky, wrote a Masters thesis on the proportions for round brilliant cut diamonds. This became the basis for what is now known as the “Ideal Cut".

It is said he asked passers by, in the streets of London, to select the most appealing diamond from a small group. From these casual observer opinions, together with those of the diamond cutters in his family's Belgian business, he confirmed the proportions of the best-looking diamonds. He then applied math and physics to prove why.

The proportions he chose produce a beautiful diamond. But it has taken more than 80 years for the industry to realize that his theorem predicted a range of proportions not just the single set of parameters. He was aware of a trade off between maximum brilliance and maximum fire that results from varying combinations of crown and pavilion angles.

In recent years, different Gem Laboratories have come up with their own parameters for what the “Ideal Cut” represents. The parameters from the Gemological Institute of America (GIA) and the parameters from the American Gem Society (AGS) are different. Many of the other Gem Labs also have very different parameters that they represent as “Ideal Cut”

Robbins Diamonds sells diamonds with grading certificates from various Gem Labs. All of these diamonds that have been labeled “Excellent Cut” or Ideal Cut are all well proportioned and are of superior “Cut”.

HOWEVER, we do stock and sell some very important brands of “Premium Diamonds” These brands are sold throughout the world in a limited number of fine jewelry stores. The prices for these diamonds are higher than generic Ideal Cut Diamonds. These Brands all have unique features that ensure a higher form of Light Performance and quality of the proportions as well as other features that make them worth more than generic diamonds. In other words, they cost more because they’re worth more to those who want the very best and can afford it.

We are proud to have been chosen as the company in our area to represent and stock these Diamond Brands:

Finding the Perfect Diamond to Match your Perfect Love

No two romances are alike, and no two diamonds are alike. But we’re confident we have the diamond that’s right for you. At Robbins Diamonds, we offer diamonds as varied and unique as the couples that buy them. We offer the very finest diamonds money can buy, we offer diamonds that are value-priced, and we offer everything in between. Here are some examples.

Premium Branded Diamonds give you the very best proportion, light performance, fire, symmetry, brilliance and sparkle attainable. As well as other features that non-branded diamonds do not offer.

Excellent or Ideal Cut Diamonds demonstrate subtle variations in character while preserving the harmony of proportion and light reflection.

Standard cut diamonds offer beauty and splendor at a very affordable price. These diamonds make the most cherished memento of love attainable to everyone.

Practical Tip: Many jewelers focus on color, clarity, and the carat weight, while ignoring the cut. But without a quality cut, diamonds lack beauty and sparkle. Other jewelers may offer an Independent Grading Certificate, but even these can be confusing. Especially when it comes to the way a diamond is cut and proportioned

So what exactly is a Premium Branded Diamond? It’s the one that makes her go “WOW!” It’s the one that makes stars dance before your eyes. It’s what puts the sparkle in everything. Put simply, it’s a diamond cut to the precise proportions that allow the very best finish and the very best reflection of light. In fact, a diamond cut either too deep or too shallow may sell for more than 50% less than a Premium Branded Diamond

At Robbins, we have Special Equipment that allows you to compare diamonds side by side and clearly see for yourself how one diamond outshines another because of its superior craftsmanship relating to the “Cut”.
