Exceptional blue stones, also known as cobalt spinels, which resemble fine sapphires, have been discovered in Sri Lanka and command very high prices. Having the hardness of 8 on the Moh s scale, with no cleavage spinels are excellent for jewelry settings. Spinel rings, spinel necklaces, spinel earrings and other types of spinel jewelry are all valuable additions to a collection. When evaluating the value of spinels, color intensity is the most important consideration. The gemstone should be intensely colored without any secondary brown tones.
Clarity is also an important evaluating factor, with eye clean spinels being highly valued.
Cutting is very important, as well-cut stones can be quite spectacular. Having a high refractive index, the brilliance of a well-cut spinel is breath taking. Ltd. All rights reserved.
