DescriptionGemstone: Colemanite - 3.29 Cts.
This is another collector gemstone which is hardly ever cut into a gemstone making these examples super rare. This nearly 3.3 carat Colemanite was mined in Turkey a top locality for the material. A gemmy crystal was then cut with great care as this material is incredibly soft and water soluble. The radiant cut stone is colorless with a slightly cloudy appearance. There is a strong doubling effect and some highly reflective fingerprint inclusions within the stone. Due to the stones soft nature there are several chips on the pavilion and culet.
Measurements: 10.39 x 9.11 x 6.20 mm, 3.29 cts.
Provenance: The Jena Blue Collection
Estimate: $500 - $700.
