3 Stone Yellow Diamond Ring- Lab

18ct Two-Tone Ring featuring a 6.07ct Fancy Intense Yellow Cushion Cut Lab Diamond, accented by custom-cut trillion diamonds and handcrafted in 18ct white and yellow gold.

For the sketch page itself, I'd have the small text underneath:

6.07ct Fancy Intense Yellow Cushion Lab Diamond
Custom Cut Trillion Lab Diamonds
18ct Two-Tone Gold
Designed & Handcrafted by Fifth Avenue Diamond Experts

"All Custom Cut Diamonds" sounds much more premium than "all custom cute diamonds" and tells the story that the trillions were specially cut for the design rather than being off-the-shelf stones.
