Heated & Treated Gemstones: Facts Every Buyer Should Know

Heated & Treated Gemstones: Facts Every Buyer Should Know
When gemstones are mined, they rarely look like the sparkling jewels we admire. Most appear dull, patchy, or cloudy, with uneven color and visible fissures. Only a very small percentage naturally come out bright and flawless.

That’s why many gemstones are gently heated or treated. This is an age-old and globally accepted practice, done only to bring out the beauty already present within the stone.
• Heating improves the natural color and clarity of gems like ruby, sapphire, tanzanite, and aquamarine.
• Emeralds are often lightly oiled to reduce the visibility of surface fissures.
• These processes are necessary to reveal the gem’s true potential and to make it suitable for fine jewellery.

Important to know:
• Heating or light treatment does not harm the life or durability of a gemstone.
• The gemstone’s natural energy and benefits remain intact.
• Both heated and unheated gemstones are good — the difference is mainly in rarity, not in quality of life or strength.

✨ Bottom line: Heating or treatment is sometimes necessary for gemstones to display their best beauty, while keeping their natural essence untouched
