Gem Note

😲😲😲 Given the size of 16.75 carats and the distinctive Tessellation cut (designed by Arya Akhavan), this alexandrite will indeed make a stunning centerpiece for a piece of jewelry. Whether set in a ring, pendant, or even a brooch, it will catch the eye with its architectural facets and shifting colors. For setting this gemstone, you might consider a simple yet elegant metal frame to let the stone's intricate cut and color be the star of the piece. Platinum or white gold would complement the cool tones of the teal, while a warmer metal like rose gold could beautifully contrast the purplish hues seen under different lighting. (Note: This gem appears more blue in photos. In reality it is a beautiful teal color).

This example of lab-grown alexandrite, produced to meet the demand for gemstone production, is especially intriguing. Unlike the usual material used by most of the industry, this substance is significantly lighter, enabling the creation of larger, brighter gems. It appears to have a high vanadium concentration and a low chromium concentration, leading to a less intense color shift but a more vibrant blue/teal hue.
