One of the rarest and most valuable gemstones, alexandrite is a luxurious birthstone for lucky
babies born in June. Alexandrite is also the traditional gift
to celebrate a 55th wedding anniversary.
Color change is the most important factor when
determining alexandrite’s quality and value. The
brighter the colors and the more dramatic the change
from bluish green in daylight to purplish red under
incandescent light, the more valuable the gemstone.
Like most gemstones (except its fellow June
birthstone, the pearl), alexandrite is weighed in
carats. Higher clarity may weaken the gemstone’s
color change, so color is much more important than
clarity in this case.
Natural alexandrite is more expensive than most gemstones,
including sapphires, rubies, emeralds, and diamonds.
Top-quality Russian authentic alexandrite has sold for as much
as $10,000 for one carat.
Most of the original Russian gemstones belong to
museums or private collectors. The few gemstones
that are produced today only fit the budgets of the
most discerning gemstone collectors.
Alexandrite is a solid investment because of its
rarity, durability, and historical significance. If
