This is a beautiful smooth polished rainbow labradorite sphere from an extensive collection that is now being offered for sale.  It has lots of chatoyant rainbows with natural color as it's found in nature.

It's a good size to work with, weighing about 180 grams (6.4 oz.) and is about 60 mm in diameter (over 2.3").

This wonderful labradorite sphere has been stashed away for many years, along with many other crystal specimen that will be listed in the near future, so it's more in the category of "new - other", and is still in the same condition as when it was purchased.
