White Corundum

White Corundum, also known as white sapphire, is a colorless variety of corundum, the same mineral species as ruby and sapphire. It is prized for its brilliance, hardness, and versatility in jewelry as an affordable and ethical alternative to diamonds.

Key Features:

1. Composition:
   • Made of aluminum oxide (Al₂O₃), with no trace elements that would otherwise impart color.
   • The absence of impurities gives it its colorless or white appearance.
2. Hardness and Durability:
   • Second only to diamond in hardness, scoring 9 on the Mohs scale.
   • Highly resistant to scratches and suitable for everyday wear.
3. Uses:
   • Commonly used as a diamond substitute in engagement rings, pendants, and earrings.
   • Its high refractive index provides brilliance and sparkle, similar to diamonds.
4. Natural vs. Synthetic:
   • Natural White Corundum: Rare in nature; most colorless corundum found in the market is synthetic.
   • Synthetic White Sapphire: Produced via methods like the Verneuil process, often used in optics, watches, and jewelry.
5. Ethical and Affordable:
   • Unlike diamonds, white sapphire is often free from controversial mining practices.
   • More affordable than diamonds while still offering a stunning appearance.
6. Care:
