Victorian Black Opal W/ Diamond Ring in 18k.  This Victorian right hand ring features a .44 carat creamy natural opal and .12 carats of accent diamonds set in 18 karat yellow gold. The scrolling metal work on the sides of the ring evokes a regal feeling that this ring would be at home on the hands of royalty. The contrast between the pure opal color and the rich yellow gold adds a new dimension to the fabulous patina so commonly found on Victorian gold.
