Grandidierite is an exceptionally rare and valuable gemstone, first discovered in Madagascar in 1902. It is one of the top 10 rarest gems in the world, known for its striking blue-green to teal coloration. High-quality Grandidierite stones are highly sought after by collectors due to their rarity, durability, and unique pleochroic properties (meaning they display different colors when viewed from different angles).
Additionally, the 14k gold setting and diamond accents add to the ring’s intrinsic and aesthetic value.
Estimated Value:
Determining the exact value of this ring requires an evaluation of:
The quality, carat weight, and clarity of the Grandidierite gemstone
The cut, clarity, and carat weight of the diamonds
The gold weight and craftsmanship of the ring
Because Grandidierite is an extremely rare gem, pricing can range widely based on quality:
Lower-grade Grandidierite stones: $500 - $2,000 per carat
High-quality gem-grade Grandidierite: $5,000 - $20,000 per carat
14k gold setting: $150 - $400 (depending on weight)
Diamonds: Additional value based on cut, clarity, and carat weight
Given these factors, this ring could be worth anywhere from $1,500 to $15,000+, depending on gemstone quality and total carat weight.
Professional Appraisal Recommended:
For an accurate market valuation, I strongly recommend a professional appraisal from a certified gemologist or jeweler who can:
Verify the authenticity of the Grandidierite stone.
Assess its carat weight, clarity, and color quality.
Determine the total diamond carat weight and quality.
Weigh the gold and factor in current market prices.
