Alma Oscura
Unique Natural Black Diamond Oval Engagement Ring
Alma Oscura is an oval black diamond engagement ring in rose gold. Its center is a 3.07 carat natural, earth-mined oval black diamond held by four claw prongs. A hidden halo of white diamonds sits under the center stone, and round black diamonds line the band. The accents add 0.37 carats, for 3.44 carats total weight.
From the top you see only black: the oval and the dark band. Turn your hand and the white diamonds under the stone show from the side. The black diamonds are natural and color enhanced, and the certificate that comes with the ring states it. A black diamond is nearly opaque, so it shines from its polished facets instead of sparkling like a white diamond (our black diamond engagement ring guide).
This listing is the rose gold version, in 14K or 18K gold, ring sizes 4 to 9 (resizable). Alma Oscura in yellow or white gold: Alma Oscura black and white oval ring. Each ring is made to order: production takes 10-14 business days, plus shipping.

Our largest black diamond centers are 5.37 carats in the Black Magic three-sided ring (6.44 carats total) and 5.14 carats in the Arkana three stone ring (5.6 carats total).
