Our most beloved setting began as a sketch on a napkin in a small cafè along the canal in the neighborhood of Jordaan in Amsterdam as we were surrounded by the vibrant, iconic tulip motifs that Amsterdam is so well known for.
Our Signature Lotus Flower petals twist up like vines into double claw prongs that hold onto the stone.
It's complete with a cathedral setting, pavè bridge detailing and a hidden halo for extra sparkle and durability.
By default, we intentionally design our rings with pavè bridge detailing on one side so you can wear the plain side towards your wedding band without worrying that it will scratch it and the detailed side facing outwards. If you would like a two-sided pave bridge, just let us know in the checkout notes and we'd be happy to add it for no additional charge. If you would prefer the no pavè bridge customization, just add it to the check out notes as well or send us an email when you place your order.
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 and ratio 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+.
Moissanite:Colorless DEF, VVS1-VVS2
Lab Diamond: Premium D or E color, VVS or VS1 clarity
All lab diamonds are GIA, IGI, or GCAL Certified
Band width: 2mm x 2mm
