This spectacular sun features an opal that contains just about every color of the rainbow! It is hard to capture, but the gold setting is actually a beautiful 14k rose gold. The opal is even more brilliant in darkness, as the colors seem to glow. This piece may be worn as a brooch, or as a pendant. The bale is hinged so it may be cleverly hidden when worn as a pin. It measure about 1 1/4 inch wide. The chain is not included. Please ask about our many options.
