La Eternidad - N1 Australian Black Opal Marquise Diamond Engagement Ring 18K Yellow Gold

Design name: La Eternidad
A rare, breathtaking ocean blue beauty representing deep, everlasting, eternal love!

Design Idea:
“La Eternidad” translates into “everlasting” or “eternal.” This 18K yellow gold ring with its central 0.72-carat Blue-Black Opal symbolizes everlasting love. You will immediately be mesmerized by its ocean-blue play of color, one that is hard to find in black opals! Surrounding the Opal centerpiece is a set of 8 Marquise-shaped 0.630-carat diamonds, whose striking white makes the opal diamond ring even more alluring. Present this black opal ring to someone you cherish deeply.

Free Domestic USPS First Class Shipping! Free Gift Bag or Box with every order!
