CGL Certified 0.40 Carat Russian Demantoid Garnet Round Rare Diamond PT 900 Ring

About the Item

One of the rarest garnet varieties, Demantoid can have a green color that rivals emerald and a fire that exceeds diamond. Demantoids are highly prized by both gem collectors and jewelry enthusiasts. Demantoid is derived from the Dutch word for diamond, "demant." The stone owes its impressive diamond-like brilliance to two main factors: A high refractive index and a high dispersion (its ability to separate light into the spectrum of colors). Demantoid, in fact, boasts the highest dispersion rating of all gemstones, including diamond. Fine-quality demantoid garnets are rarely found in sizes larger than 2 carats, a fact that makes the examples on this page all the more impressive.
