FORMATION: Alexandrite’s formation is an incredibly rare phenomenon. The gemstone is the color changing variety of the chrysoberyl mineral. Alexandrite will only form when aluminum and beryllium combine with elements of iron, titanium and most importantly, chromium. Chromium causes the color of alexandrite to shift with light. During the daylight, alexandrite will shimmer with hues of green and purple in lamp light. Chromium’s rarity makes alexandrite one of the most valuable gemstones.

TREATMENTS: Alexandrite gemstones are typically untreated, but imitation stones do exist. Alexandrite stones may be dyed or oiled, but this is not very common.

Synthetic Alexandrite has been available on the market since the 1960s.
