Australian 6.77ct Opal Platinum & 18K Gold and Marquise Diamond Ring

A spectacular vintage opal and diamond statement ring centered by an impressive 6.77-carat oval cabochon opal, surrounded by approximately 1.02 carats of marquise-cut diamonds and beautifully crafted primarily in platinum with 18K yellow gold incorporated into portions of the setting and prong work.

The opal is unquestionably the star. As the ring moves through the light, the stone displays a beautiful and constantly changing play-of-color, with visible flashes of red, orange, pink, green and blue across its light body color. Its generous 6.77-carat size gives the ring exceptional presence on the hand while allowing the natural character of the opal to take center stage.

Surrounding the opal is a dramatic halo of marquise-cut diamonds totaling approximately 1.02 carats. Rather than a traditional round-diamond halo, the elongated marquise diamonds radiate outward around the opal, creating an elegant petal-like silhouette and giving the ring wonderful dimension.

The construction is particularly beautiful. Platinum forms the primary structure of the ring, providing the crisp white backdrop traditionally favored for diamond-set fine jewelry, while 18K yellow gold is used in portions of the setting and prong work. The subtle mixed-metal construction adds another layer of craftsmanship and character to the piece.

The combination of the colorful opal, bright marquise diamonds and substantial precious-metal construction gives this ring the kind of presence that is difficult to reproduce in modern jewelry.

And that is part of the appeal of a great vintage opal: there simply isn’t another one exactly like it. Its individual pattern and play-of-color change constantly depending on the light and viewing angle.
