In 2000, The Star 129 mission was to develop a cut with a difference that anyone could see. A diamond that could be seen with just your eyes – no special lights, no magnifying devices. So, we set out to create the first and brightest multi-faceted round diamond on the market.

The Star 129 is much brighter than a traditional round diamond. Using a complex geometrical formula, precise interplay of each facet, and the proportions of the stone, its brilliance radiates in a way that was not possible before. The latest technology and research reveal that the inter-relationship of facets, as opposed to any specific proportions, ultimately determines the brilliance of a diamond. The results are clear: no matter the view, light or distance, the Star 129 is more brilliant.

Every Star 129 is ideally cut. We have increased the number of facets to maximize the beauty of the diamond without compromising the refractive properties. Research by GIA shows there are multiple cut grades that can create an optimal performing diamond. Each Star 129 has its own unique balance of angles and proportions specially selected for each diamond, working together to create the tremendous light performance and beauty of each individual stone. With each Star 129 purchase, you will receive a Gemex Light Performance and diamond certification from an independent lab with the specifics of your diamond.
