I sold this before and ended up canceling order , so reposting 16 inches long total Crafted in solid platinum!! Reversible!! One side is genuine alexandrite and the other side is genuine diamond!! This used to just be diamonds and the jeweler added a custom picked alexadrite , so the carat stamps on the pendant aren't accurate since gems were added after Photos 8-9 show stamp on bale and pendant photos 4-5-6 show size comparison.
