Overview
This whimsical 10-karat yellow gold ring is designed in the form of a stylized beetle or cicada, featuring a smooth, luminous moonstone cabochon as its abdomen. The insect's wings are encrusted with delicate, lavender-blue tanzanite stones, creating a beautiful play of light and color.
Story
Discovered in East Africa in 1967, tanzanite became a global sensation. This ring pairs that modern, exotic gemstone with moonstone, a classic staple of ancient folklore, to create a charming, wearable piece of natural history.
Maker / Origin
The ring bears the maker's mark 'JCR', which is associated with John C. Rinker, an American jewelry manufacturer known for producing high-quality, creative gemstone jewelry in the late 20th century. Rinker's designs often featured playful natural motifs and unique gemstone combinations.
Condition & Value
The ring appears to be in very good vintage condition with minor surface wear to the gold band. All stones appear intact and secure in their settings. Excellent condition with no chipped stones commands the higher end of the value range.
