When you shop for opals you'll find significant differences in opal appearances and qualities
. Many opals for sale are solid gems, but some are composites, called doublets or triplets
. A composite opal is made of a thin slice of real opal that is mounted to the top of other, cheaper materials. There's nothing wrong with buying doublet and triplet opals as long as the seller discloses that they are composites and you pay an appropriate price for them.
1) 14k Yellow Gold Genuine Opal and Diamond Ring
The central stone in this diamond and opal ring is a 10 x 5 mm marquise cabochon opal that's graded "A" in quality. Six round, brilliant cut prong set diamonds surround the opal. Set in 14K polished yellow gold.
2) Heart Shaped Opal in Claddagh Setting
Fans of Claddagh settings will like this heart shaped opal set in 14 karat gold. The band tapers down from crown and hands that hold the opal so that the ring is more comfortable to wear.
3) Australian Opal Inlaid in White Gold, with Diamonds
This opal ring is hard to describe, but it's my favorite ring in this collection. It's designed with differently sized slabs of Australian opal that are inlaid into sterling silver. The sterling flows around each opal to create a lovely frame. Four diamonds are set in a row at the ring's center -- they move across the width of the band.

This ring is very unusual, but pretty. There's a large blue fiber optic at its center, surrounded by twenty-eight triangular and rectangular lab created opals in shades of blue. All stones are bezel set in sterling silver.

A prong set oval sits in the focal spot of this 14K ring. It's flanked on either side by a row of small, round channel set diamonds. Simple lines enhance the opal.

A Brazilian fire opal is set in 14 karat yellow gold and surrounded by sixty small round diamonds and two yellow sapphires.
