Alexandrite

[TG_GEMSTONE]

[TG_INTRO]
Alexandrite is a rare and fascinating variety of chrysoberyl celebrated for its remarkable colour-changing appearance. Depending on the light source, a fine alexandrite may appear green to bluish-green in daylight and red to purplish-red under incandescent lighting. This unusual optical effect, known as the alexandrite effect, makes the gemstone highly desirable among collectors and jewellery enthusiasts. Its rarity, distinctive beauty and excellent durability have made it one of the most intriguing coloured gemstones in the world. At Tanishq Gems, we help customers explore alexandrite gemstones and understand their characteristics before making a purchase.

Alexandrite is a durable gemstone, but proper care helps maintain its appearance and protect its setting.

**Clean gently:** Use lukewarm water, a mild soap and a soft brush when appropriate. Rinse carefully and dry with a soft cloth.

**Avoid harsh chemicals:** Keep alexandrite away from bleach, strong cleaning products and other substances that may damage jewellery settings.

**Store separately:** Store the gemstone or jewellery in a soft pouch or a separate compartment to prevent scratches to other jewellery.

**Protect the setting:** Remove rings and other jewellery before strenuous activities, heavy work or activities that may cause impact.

**Check jewellery regularly:** Have prongs and settings inspected periodically by a qualified jeweller.

**Follow specialist advice:** If the gemstone has undergone treatment or is set in delicate jewellery, confirm suitable cleaning methods with the seller or a qualified jeweller.
