Because gemstones, no matter the type, tend to be a significant financial investment, it is essential to know the qualities characterized by high-quality peridot before deciding on one to purchase. During this selection process, keep “The Four Cs of Gemstones” in mind to help you find your ideal stone:
Color: Peridot is one of the few types of gemstone that forms in only one color – olive green. Depending on the amount of iron present, however, the tint and intensity may differ between stones, resulting in an assortment of yellowish and brownish-green varieties of olive green.
Clarity: The majority of the higher-quality, standardized material – as well as the larger single pieces – on the market do not have any eye-visible inclusions. It does, however, have tiny black spots, which are actually microscopic mineral crystals, observable under magnification. Other common inclusions in this gemstone are reflective, disk-shaped inclusions called “lily pads.” These inclusions that are very plainly visible, especially the dark spots in light-colored crystals, tend to lower the stone’s value.
Cut: In terms of cut, there isn’t one specific shape that out-values another. Peridot is cut in many shapes, including oval, pear, round, emerald cut, cushion cut, triangle cut, and marquise. Similarly, brilliant cuts that have triangular and kite-shaped facets, step cuts showcasing concentric rows of parallel facets, and mixed cuts consisting of brilliant-cut crowns and step-cut pavilions are each common styles, as well.
Carat: Peridot is known to be one of the more affordable green gemstones available, often divided into two different grades based primarily on intensity of color – its best color found in stones of 10 carats or greater. Generally, darker versions of the stone are more expensive. The price for medium or darker shades of the stone might go for about 45 – 70 dollars per carat, while lighter shades could go for about 35 dollars per carat.
