The Colors of alexandrite

The most striking feature of alexandrite is its color change. From bluish green in daylight to a purplish red at night, this gemstone has an appealing mysterious quality. Typically, the more noticeable the change in color, the more valuable the gemstone is. Those with moderate to strong color saturation are highly rare and valuable.

Alexandrite's color change is a result of its rare chemical composition. Part of the chrysoberyl mineral group, it contains iron, titanium and – crucial to its unique colors- chromium. Alexandrite is the only chrysoberyl that appears to change color in different lights.

Grading alexandrite

While there is no standardized grading system for colored gemstones, their value is typically ascertained by their size, color, and clarity. When shopping for an alexandrite gemstone, consider those with very few visible blemishes. Alexandrite gemstones are typically eye-clean, meaning that imperfections are not detectable without magnification.

Those with strong colors, a lack of eye-visible inclusions and a clear change in color are the most desirable. Sometimes a thin inclusion called a needle will result in a cat-eye effect across the gemstone. These are rare and greatly increase the value of alexandrite. Ritani only sells the finest, hand-selected alexandrite.

This gemstone's stunning ability to change color depending on the quality of light makes it a versatile choice for precious jewelry. It can be set in a variety of metals and looks just as stunning in yellow and rose gold, as it does in white metals. The mystical effect of alexandrite lends itself to vintage and antique designs, although its use in modern jewelry styles can be truly striking.

Choosing Your alexandrite

Every alexandrite offered by Ritani is of the finest quality, hand-selected for its beautiful color. For the best value, we recommend opting for those with medium-light to medium-dark tones, and light to moderate inclusions. These criteria will ensure that your gemstone does not have noticeable blemishes that distract from its stunning hue.

Ritani stands by the quality of each of its gemstones, offering free 30-day returns for all orders. Our certified gemologists are available to help you make the right choice.

Caring for your alexandrite

Alexandrite and other chrysoberyl are positioned at 8.5 on the Mohs hardness scale – just behind rubies, topaz and diamonds. This makes them an ideal choice for durable gemstone jewelry to last through the generations. The stones are resistant enough to be worn everyday, through normal wear and tear.

It is still important to take care of your alexandrite, however. Clean them regularly with warm, soapy water. Only use ultrasonic and steam cleaners if your gemstone does not have any significant fractures. Always store your alexandrite jewelry separately, so as to not chip and scratch other pieces in your collection.
