From Our Designer

The 1.5 Carat Diamond occupies a sweet spot — noticeably larger than 1 carat, yet more attainable than 2 carats.

When clients come to me with a 1.5 carat diamond, I often recommend halo settings. The surrounding diamonds amplify the center stone's brilliance and add visual size. But a well-cut 1.5 carat solitaire is equally stunning.

My approach is collaborative. I'll show you CAD renderings before we cut metal. We refine together until every detail is perfect.

Every diamond is hand-selected by our gemologists for optimal cut, color, and clarity.
