This bespoke design traces back to the very beginning: an opal gifted to Jillian by her grandmother Mary became the spark that started Marrow. In honor of our 10-year anniversary, we’ve revisited that original heirloom with a small run of one-of-a-kind opal rings.

The ring features a 4.45ct Australian Opal beneath a black diamond headdress (1.32ctw), accented with two emerald brilliant cuts (0.23ctw). Set in 14k yellow gold, this is a striking cocktail ring that stands out on any finger. Jillian wears hers on her pointer finger.
