2.90 Ct Cushion Blue Sapphire Diamond Halo Pendant
2.90 Ct Total | Cushion Cut | Blue Sapphire | Diamond Halo
Center: 2.50 Ct Cushion Blue Sapphire (8mm, Lab-Grown) | Accent Diamonds: 0.40 Cts | Total: 2.90 Ct | 16–18" Adjustable Cable Chain Included
A cushion-cut blue sapphire at 8mm is a serious stone — deep color, substantial presence, set inside a full diamond halo that sharpens the contrast between the blue center and the white accent stones. Handset in our New York City studio in the Diamond District.
Lab-grown sapphires are real sapphires — not simulants, not cubic zirconia. Same chemical composition, same optical properties as mined, grown above ground and sold direct from the maker. No retail markup means more stone for your investment.
A strong choice for a milestone gift, a non-traditional engagement pendant, or a standalone piece built to last.
