Purplish Red 6 Ray Star Ruby Heated 7.5 11.6x9.5mm oval Cab From Africa.
A ruby is a precious, blood-red colored gemstone and a variety of the mineral corundum. Its striking color comes from the element chromium. It is prized for its rarity, durability (ranking 9 on the Mohs scale), and status as the traditional birthstone for July.
Key Characteristics
-
- Color: Ranges from orange-red to purple-red. The most valuable, sought-after hue is a vibrant "pigeon blood" red.
- Durability: With a 9 on the Mohs hardness scale (just below a diamond), it is highly resistant to daily wear.
- Rarity: Gem-quality natural rubies are significantly rarer than diamonds.
- Treatments: Many natural stones undergo heat treatment to improve color and clarity. Some lower-quality stones are fracture-filled with glass, which requires careful cleaning.
