Description

This Alexandrite simulant is crafted from lab-created synthetic purple corundum, displaying a distinctive greyish-purple hue. With a hardness rating of 9 on the Mohs Scale, these stones offer excellent durability suited for everyday wear. Their round faceted cut delivers classic brilliance, and calibrated sizing ensures consistent fitting across a wide range of settings. Note that calibrated gemstone sizes may vary slightly by +/–0.10mm.

These simulants are particularly versatile for studio jewelers—they are safe to fire in metal clay and can be cast in place, making them a practical choice for a variety of fabrication techniques. Clean with warm, soapy water; use of an ultrasonic or steam cleaner is generally safe.

Do these stones change color based on lighting like Alexandrites and color change Sapphires? The wording in the specifications seems to imply the latter.

These stones are imitation Alexandrites so they don't have the same characteristics as the genuine stones. They are meant to come close to matching a standard of color only.
