A custom cut old mine oval lab diamond rests within our beloved Latticework Tulip Prongs; a romantic bloom of petals that weaves around the center stone.
Bijou Lab's antique faceted oval cut lab diamonds are cut uniquely with very specific parameters to achieve a tailored and unique look. And extra long and skinny bar culet, an elongated but balanced ratio and extra chunky and scintillating pavilion facets lead to a very refined and signature end result.
This ring features our brand's signature Vintage Pave Bridge; an ode to both the old and the new, a dual-sided sparkling arch of hidden diamonds with an enchanting milgrain border to add a touch of vintage beauty underneath.
Our design's proprietary overlapping tulip petals are not only beautiful; they give the prongs added security due to the interlocking nature of every prong. A regal tapered cathedral is the finishing touch that adds both support and elegance.
The Vintage Pave Bridge feature was designed with extraordinary intention so the stones are set slightly recessed and the milgrain is set above the level of the stones to form a small barrier so your wedding band doesn't get scratched by the stones and your wedding band doesn't subsequently wear down the prongs holding the pave (leading them to fall out). This means the pave bridge can safely be featured on both sides of this ring.
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, excellent polish and excellent symmetry.
Our specialty diamond cuts minimize or eliminate the bow-tie effect for optimal performance. Read more about our Bespoke Diamonds here.
