Mare Nubium Gray Spinel engagement ring
18k gold and gray spinel
Long ago it was believed that there were beautiful seas and lakes of water on the moon that were visible from Earth. Galileo looked through his telescope and named them all. This ring is named after one of those lakes, the Mare Nubuim.
A bold and classic style with an ancient silhouette, created here with gorgeous gray spinel and black diamonds, and cast in solid 18k recycled yellow gold.
The subtle flare and sculpted style on the ring shank refers to an old European style of ring that is comfortable to wear.
