When you buy an Alexanrite Ring from Alaska Jewelry, you are guaranteed to be purchasing a natural Alexandrite. We do not carry immitation or lab grown Alexandrite. Our stones come from India, Africa, Brazil, and we sometimes have one or two Russian Alexandrite stones. We carry a wide range of qualities, which are reflected by the prices. All of our Alexandrite is hand selected for color and color change, and we do not carry the lowest quality stones that show brown, yellow, or zero color change. The most affordable stones (under $3000) will generally be from Africa or India, while the most valuable (highest quality) come from Brazil.
