This heated 5.88-carat cushion pinkish red Madagascan sapphire and diamond ring is a new design by David Gross Group. The sapphire is complemented by about 0.34 carats of epaulet-cut diamonds, all set in a platinum band. This size 7 ring is not resizable but stands out for its environmentally responsible, conflict-free sourcing and artisan craftsmanship. It comes with an AGL report verifying the sapphire's size, origin, and light heat treatment.
