Our most popular setting began as a sketch on a cappucino napkin in a tiny cafè along the canal in the neighborhood of Jordaan in Amsterdam; surrounded by the vibrant, iconic blooms of tulips that Amsterdam is so well known for.
Our romantic Signature Lotus Flower petals twist up like vines into double claw prongs that encompass the sparkling radiant center stone. A milgrain Vintage Pavè Bridge is featured on both sides of this ring for a hidden touch of old world beauty.
It is finished with a regally tapered cathedral setting, sweeping vintage pavè bridge detailing underneath and a hidden halo on the sides for extra sparkle and durability.
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+.
Cut: Oval (Brilliant)
