Alexandrite: the Ultimate Jewellery Guide

Few gemstones are as mysterious and enchanting as alexandrite. Famous for its rare ability to change colour under different lighting, alexandrite is often described as “emerald by day, ruby by night.” This mesmerising quality makes it one of the most sought-after and romantic gemstones in the world.

History & Symbolism of Alexandrite

Discovered in Russia’s Ural Mountains in the 1830s, alexandrite was named after Tsar Alexander II and quickly became associated with Russian royalty. Its dramatic shift between green and red hues symbolised balance, duality, and transformation.

Across history, alexandrite has been linked with creativity, intuition, and good fortune. Today, it is considered a gemstone of luck, passion, and personal growth.

Alexandrite is the birthstone for June (alongside pearl and moonstone), and it’s also the gemstone for the 55th wedding anniversary.

The Magic of Colour Change

Alexandrite’s unique appeal lies in its play of colour:

  • Daylight or fluorescent light: Green to bluish-green.

  • Incandescent light (lamps, candles): Red, purplish-red, or raspberry tones.

This rare optical effect is caused by trace amounts of chromium in the crystal structure, making fine alexandrite incredibly valuable.

Popular Alexandrite Jewellery Styles

  • Alexandrite Engagement Rings – A rare and romantic alternative to diamonds.

  • Halo & Three-Stone Rings – Pairing alexandrite with diamonds for contrast.

  • Alexandrite Pendants – Showcasing the gemstone’s colour-changing beauty.

  • Vintage-Inspired Designs – Nods to its 19th-century Russian heritage.

  • Statement Earrings – Highlighting the stone’s shifting tones in elegant drops.

How to Choose a Quality Alexandrite

  • Colour Change: The stronger the shift between green and red, the more valuable.

  • Clarity: Eye-clean stones are highly prized, though inclusions are common.

  • Cut: Oval, cushion, and round cuts maximise colour and brilliance.

  • Carat: Large alexandrites are exceptionally rare, with prices increasing dramatically with size.

Caring for Alexandrite Jewellery

With a hardness of 8.5 on the Mohs scale, alexandrite is durable enough for daily wear with proper care.
Care Tips:

  • Clean with warm soapy water and a soft brush.

  • Avoid ultrasonic or steam cleaners.

  • Store separately to prevent scratches on softer gems.

  • Remove rings before strenuous activity or contact with chemicals.
