Opal is widely prized for its unique play of color (in other words, its unique quality of diffracting light into rainbow flashes) and considered by many to represent fidelity, hope, and purity. This dazzling, marquise-cut Ethiopian opal now has a fitting home in a gold-and-diamond piece that is as much jewelry as it is pure art. A 16-inch chain dangles this resplendent pendant, accenting the opal in a webbed-gold and diamond-encrusted frame.
