Everything You Need to Know

What is lab-grown alexandrite?

Lab-grown alexandrite is alexandrite created under controlled conditions rather than formed naturally underground. Alexandrite is a variety of chrysoberyl valued for its distinctive response to changing light.

Is lab-grown alexandrite a real gemstone?

Yes. Lab-grown alexandrite is a real gemstone created through a different growth process. It shares the essential crystal structure and mineral characteristics associated with alexandrite.

Why does alexandrite appear to change color?

Alexandrite interacts differently with the wavelengths present in different light sources. Because daylight, indoor lighting and other environments have different light characteristics, the gemstone may appear to shift in tone.

The strength and direction of this visual change can vary from stone to stone.

What colors can alexandrite display?

Alexandrite can display a range of tones depending on the stone and lighting environment. Blue-green, teal, violet, purple and warmer tones may be visible, but the exact color shift should not be expected to look identical in every gemstone or under every light source.

Is alexandrite suitable for everyday jewelry?

Alexandrite measures approximately 8.5 on the Mohs hardness scale, giving it very good resistance to scratching and making it well suited to regular jewelry wear.

As with all fine jewelry, the gemstone and setting should still be protected from strong impacts and abrasive surfaces.

What is the difference between lab-grown and natural alexandrite?

The primary difference is origin. Natural alexandrite forms through geological processes, while lab-grown alexandrite develops within a controlled growth environment.

Growth characteristics, inclusions, availability and pricing may also differ.

Does lab-grown alexandrite fade over time?

Its inherent gemstone color does not normally fade through ordinary wear. Oils, lotions and surface residue can make the stone appear temporarily less bright and can usually be removed through gentle cleaning.

How should I care for alexandrite jewelry?

Clean alexandrite jewelry using lukewarm water, mild soap and a soft brush. Rinse carefully and dry with a soft, lint-free cloth. Avoid harsh chemicals, abrasive cleaners and strong impacts.

When not being worn, store your piece separately in its original STDIAM walnut wood box to help reduce contact with other jewelry.
