Ideal Cut - The King of Cut:
In 1919, mathematician Marcel Tolkowsky published Diamond Design:  A Study of the Reflection and Refraction of Light in Diamond.   In his paper, Tolkowsky described diamond cutting specifications that would maximize a diamond’s brilliance.   His cut was the basis for what is now known as the Ideal Cut.   For years, the Ideal Cut has been considered the most brilliant 58 facet cut.
A diamond sold as an Ideal Cut in today’s market usually falls within the ideal range.   For instance, the table (top facet) is usually between 53% and 57% of the diamond’s diameter.   There are many other things a cutter must consider when attempting to achieve maximum brilliance.   Some of them are: crown angle, pavilion angle, overall proportions, girdle thickness, facet placement, facet shape, and more.   Each of these measurements have their own ideal range.   How they relate to each other also affects the overall brilliance.  A well executed Hearts and Arrows Ideal Cut diamond is the most brilliant of diamonds within the ideal range.   Hearts and Arrows diamond cutters spend more time maximizing the brilliance and beauty of their diamonds.
Hearts and Arrows 'Super Ideal' Cut:
Since 1919, the Ideal Cut has been regarded as the finest cut available. However, not all Ideal Cut diamonds are created equal. Some major manufacturers mass-produce Ideal Cuts using machines specified to cut diamonds that fall within the ideal range. Some of the diamonds cut in this way are top quality. Many others could barely be classified as an Ideal Cut.
Other Ideal cutters are very meticulous and cut their diamonds as if each one were a masterpiece. Hearts and Arrows diamonds are the most brilliant of Ideal Cut diamonds. Diamond cutters that produce diamonds for the mass market are usually instructed to cut a diamond quickly and to preserve as much carat weight as possible resulting in a diamond that is not as brilliant as it could be.  Hearts and Arrows diamond cutters are instructed to make a diamond as beautiful and brilliant as possible. Their goal is not to cut a diamond quickly, but to cut it perfectly.
Star 129 Cut:
The STAR 129 is a new round cut that has been developed using modern technology.   Unlike the traditional 58 facet round brilliant diamond, a STAR 129 has 129 facets. Like the Ideal Cut, the STAR 129 diamond is cut to maximize brilliance.   We have seen several new cuts over the years, but no cut has been able to outshine the Hearts and Arrows Ideal Cut.   The STAR 129 was the first cut that could compete with the Hearts and Arrows when it comes to brilliance and overall beauty.
A Revolution in Brilliance
For nearly 100 years, no cut has been shown to be more brilliant than the traditional 58 facet round ideal cut diamond - until now.   With 129 facets, the STAR 129 diamond outshines all other diamonds.   We have personally tested several cuts using Gemex's Light Performance Analysis.   The STAR 129 returned more light than the finest cut 58 facet stone.
The People's Choice
A diamond's cut greatly influences the beauty of a stone.   To demonstrate this, we decided to conduct a survey.   We showed 148 customers three diamonds side-by-side.   The diamonds were nearly identical (color, clarity, carat weight) except for their cut.   The first was a STAR 129, the second was a Hearts and Arrows Ideal Cut, and the last diamond was an average commercial cut.   Without telling them anything about the diamonds, we asked them which diamond they liked best.   Over 64% of our customers chose the STAR 129 as their first choice.
The People's Choice Test:
Over the years, many new branded cuts have been introduced and most of them did not impress us.   After seeing so many cuts come and go, we doubted that any cut would be developed that could outshine the Hearts and Arrows Ideal Cut.   Then we were shown the STAR 129, a new cut with 129 facets.   This diamond looked impressive next to a Hearts and Arrows Ideal Cut.   It was hard to compare the two.   Both diamonds were very brilliant, but they were different.
We decided to conduct a survey to see which cut our customers preferred.   We used three nearly identical diamonds.   Each diamond had nearly the same color, clarity, and carat weight.   The only difference between the three diamonds was their cut.   The first diamond was an average commercial cut round brilliant diamond.   The second was a Hearts and Arrows Ideal Cut.   The third diamond was the new STAR 129 cut.
We put the diamonds side by side in a tray and showed our customers the diamonds.   We asked them to tell us which diamonds they thought were the most beautiful and to rank them.   We didn’t want to influence their decision, so we didn’t tell them anything about the diamonds before they chose.   We conducted this survey with 148 individuals.
The results of this survey seemed to agree with the results of Gemex's "Light Performance Analysis" for these diamonds.   Our customers' preference for a particular cut corresponded with its measurable brilliance.
Our survey shows that " you don't need to be a gemologist to appreciate a well cut diamond".
Anybody can tell the difference between a well cut and a poorly cut diamond.
