Opal and Tanzanite Ring Value Guide

This vintage 14K yellow gold ring is a striking example of late 20th-century jewelry design, pairing the ancient allure of opal with the exotic blue-violet brilliance of tanzanite. Originating from the United States between 1970 and 1990, it represents a unique era where traditional 'play-of-color' stones were first integrated with then-newly discovered Tanzanian gemstones.

What affects the value of Opal and Tanzanite Ring?

• The intensity and variety of colors visible within the opal's fire significantly impact the $350-$450 price range.
• The saturation of the tanzanite stones; deeper blue-violet tones typically command higher market interest.
• Overall condition of the 14K yellow gold band, including any signs of thinning or previous resizing that might affect structural integrity.
• The clarity and lack of 'crazing' or surface cracks on the opal, which is essential for maintaining the ring's value.

How to Identify Opal and Tanzanite Ring?

• Check the inner band for a '14K' hallmark, signifying the standard gold purity used in US manufacturing during the 1970-1990 period.
• Examine the central opal for a genuine play-of-color rather than a repeating pattern found in synthetic doublets or triplets.
• Verify the tanzanite stones for their signature trichroic nature, showing shifts between blue and violet hues under different lighting.
• Inspect the setting for the specific oval-cut opal center surrounded by a halo of smaller tanzanite accents.

History of Opal and Tanzanite Ring

Opal has been admired for centuries for its unique play-of-color, with ancient Romans considering it a symbol of hope and purity. Tanzanite, a more recently discovered gemstone, was found in Tanzania in 1967 and quickly gained popularity for its striking blue-violet hue. This combination of an older, traditional gemstone with a newer, exotic one makes this ring a fascinating piece of jewelry history, reflecting a blend of classic design and contemporary gemstone trends.
