0.38ct Brazilian Alexandrite Green - Round

• Alexandrite is one of the most fascinating coloured gemstones, prized for its ability to shift colour under different lighting.
• Fine natural alexandrite is rare, especially when the colour change is strong and the stone has attractive clarity and cutting.
• As a chrysoberyl, alexandrite has a Mohs hardness of 8.5, making it one of the more durable coloured gemstone options for carefully designed jewellery.
• Alexandrite is especially suited to clients who want a gemstone with mystery, rarity and a more unusual story than traditional blue, green or red gems.
• We assess alexandrite individually for colour change, body colour, clarity, cut, origin and setting suitability.

What makes alexandrite special?

Alexandrite is famous for colour change. It can appear different under daylight, fluorescent light, incandescent light or warm evening light. The strength and attractiveness of this colour shift are major parts of its appeal and value.

Is alexandrite suitable for an engagement ring?

Alexandrite can be a strong coloured gemstone choice for an engagement ring. It has a Mohs hardness of 8.5, which is harder than many coloured gems, though still below sapphire, ruby and diamond. A secure setting and sensible design remain important.

Does every alexandrite change colour strongly?

No. Alexandrite varies widely. Some stones show a dramatic shift, while others show a more subtle change or a shift between related colours. Colour change should always be judged in real lighting, not only from a description.

How should alexandrite jewellery be cared for?

Alexandrite is relatively durable, but jewellery should still be protected from hard knocks, harsh chemicals and unnecessary heat. Clean gently with warm soapy water and a soft brush, and have rings checked periodically.

Alexandrite sourcing is about rarity, colour change and honest assessment. Origin can be interesting, but the stone’s colour behaviour, clarity and cut are central to how it should be valued.

Our alexandrite selection includes natural alexandrite such as Brazilian material. Each stone is assessed individually, especially for the way it responds to different lighting conditions.

Where treatment information is available, we disclose it. Natural untreated alexandrite can be especially appealing when it has attractive colour, clarity and a pleasing colour shift.

For custom jewellery, we favour alexandrite designs that allow the stone’s changing colour to be enjoyed while protecting it in a secure, wearable setting.
