Project of the Month
Engagement & Wedding Rings made of 18K White Gold with a 9ct Radiant-Cut Diamond
We began by finding the perfect central 9ct E-VVS2 EX-EX CVD IGI lab diamond. The process took a few weeks, as our customer wasn’t completely sure about the size. To help, we shared some tips on choosing the right fit, and in the end, 9ct was the clear winner.
Next, we provided several IGI-certified options and carefully selected the best one, considering both the diamond’s properties and the position of its inclusions.
The design phase was simple, as she already had a clear vision. With details like gem size, band width, and overall style confirmed, our designer brought everything beautifully to life. Once the design was sent over, it was approved right away.
From there, the manufacturing process began, and just 14 days later we were proud to deliver another dream that became reality.
