Digital gemstone trading platform Gembridge has launched a unique collection of phenomenal gemstones that feature extraordinary optical effects.
The Phenomenal Gems collection comprises phenomena such as:
- Chatoyancy or cat’s eye effect in cat’s eye chrysoberyl
- Asterism in corundum
- Change of color in various gemstones, mainly sapphires, alexandrites and garnets.
“The title of this collection says it all: some stones interact with light in ways that give them unusual optical effects, or phenomena,” says Commercial Director Jean Jureidini. “There are phenomenal gems at all market levels and budgets.”
Having a gemstone that exhibits a phenomenon adds rarity and value to jewelry, and is sometimes given esoteric meanings and worn as an amulet. Such gems are sought after by connoisseurs and gem collectors.
Highlights from the Phenomenal Gems collection:
Lot 23173: A rare variety of chrysoberyl, this pair of untreated alexandrites from Brazil exhibit a change of color phenomenon. From bluish green in daylight, to purple in incandescent light.
Lot 21169: An exceptionally large (120.25 ct) pair of no heat round blue sapphires with distinct trapiche asterism pattern from southern Vietnam. This phenomenon commonly found in emeralds is comparatively rare in corundum and especially in sapphires.
Lot 2138: This 14.47 ct Ceylon oval cabochon blue sapphire exhibits an asterism phenomenon when viewed from directly above. It features six bright rays of equal length.
Lot 005: Exceptional in size and quality, this one-of-a-kind 143.33 ct untreated color change garnet from Tanzania is one of nature’s wonders.
