1.70 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green sapphire from The Natural Sapphire Company is an oval shaped gemstone weighing 1.70 carats, with measured dimensions of 7.32 by 6.20 by 4.34 millimeters. Its mixed brilliant cut is designed to balance brightness, depth, and face up appeal, allowing the intense color intensity to present clearly across the crown and through the body of the stone. The color shows a refined combination of blue and green, with a saturated appearance that gives the gem a distinctive visual character while remaining elegant and wearable. The polish is graded excellent, supporting a clean surface finish and precise light return from the facets. Its clarity is very slightly included, evaluated at eye level, meaning minor internal characteristics may be present but are limited in their visibility during normal viewing.

This sapphire has received no enhancement, an important attribute for collectors and clients who value natural color and untreated origin. Sourced from Madagascar, a respected source for fine sapphires, this gemstone offers both natural appeal and reliable gemological identity. On the Mohs scale of hardness, sapphire ranks 9 out of 10, placing it just below diamond, which ranks 10, and above many commonly worn gemstones such as topaz at 8 and quartz at 7. This high hardness makes sapphire highly resistant to scratching and well suited for rings, pendants, and other jewelry intended for regular wear. As a member of the corundum family, it shares the same hardness as ruby, making it one of the most durable colored gemstones available. With its 1.70 carat weight, oval outline, intense bluish green color, excellent polish, untreated status, and Madagascar origin, this sapphire represents a well documented and practical choice for a custom jewelry design or a refined gemstone collection.
