Lab Diamond Center
The center of this ring is a gorgeous 1.78 carat oval lab-grown diamond. Lab diamonds are identical to natural diamonds physically, optically, and chemically. The difference is they are grown above ground instead of mined from inside the earth. This makes lab diamonds extremely eco-friendly and 100% free from conflict. Because their creation requires much less labor and material than natural diamonds, they are about 30% more affordable, and they are beautiful. One of a Kind Engagement Rings
Trillion Accents
On either side of the oval diamond, there is a trillion diamond. These give the ring an appearance of one large unique center stone spanning across the entire width of the finger and tapering at each end. These trillions have straight sides, instead of curved, and they are equilateral triangles. Trillions are available with both curved and straight sides. Three Stone Engagement Rings
Basket Details
Under the center stone, there is a bezel-set diamond on each front, facing outward. Under the trillion diamonds, there are tiny twists of filigree, which add a whimsical, vintage touch to the ring design.
Customization
This beautiful ring can be customized however you'd like. Many clients choose their favorite gem or birthstone to set in the peekaboo position or incorporate a particular design into the filigree. To evoke a more vintage aesthetic, the accent diamonds could be replaced with hand engraving.
