0.85ct Argyle Diamond Cushion Ring
A 0.85-carat champagne diamond set kite-wise and low profile in four sculpted claw prongs. The knife-edge shank keeps the lines clean, letting the warm champagne color take center stage. Natural carbon inclusions mark it as one of a kind.
This one of a kind ring is ready to ship in size 6.25.
Available for resize 5-8.5 — please note your required size in the notes and allow up to 3 weeks for this service. If you need the ring by a specific date, please indicate it in the notes at checkout or email me, and I'll do my best to accommodate it.
