Glittering petals blooming within the center of this captivating flower gemstone cut with 161 sparkling facets; the epitome of fine gem cutting.
For the lover of flowers, a portuguese cut round center stone rests within our signature Latticework Tulip Prongs and a regal tapered cathedral.
A golden bridge underneath, adorned with dancing flowers and a weaving vine is reminiscent of the wild blooms in the mediterranean landscape along the French Riviera.
Our design's proprietary overlapping tulip petals are elegant yet secure due to the interlocking nature of every prong.
We custom cut and hand select the top quality lab diamond center stones for every ring which are guaranteed premium D or E color and completely eye-clean VVS/VS1 clarity.
Our specialty diamond cuts minimize or eliminate the bow-tie effect for optimal performance. Read more about our Bespoke Diamonds here.
We custom cut or custom source stones with ideal cut proportions for optimum light return and minimal to no bow tie in our elongated cuts.
Stones are guaranteed excellent symmetry and polish.
We are picky with who we work with and only source and produce from a small number of high-quality, eco-conscious growers and screen for blue, gray, and brown color tinges, strain and striation to ensure you receive only the most premium lab diamonds available on the market.
Pavè stones in rings with a moissanite center stone are moissanite by default unless stated otherwise.
Pavè stones in rings with lab diamond center stones are automatically upgraded to lab diamonds.
Pavè stone quality is DEF VS+.
