Tanzanite is commonly heated at low temperature to improve its color.
There is currently no scientific method available to determine whether this
gemstone has been enhanced or not.
Minor amount of clarity enhancement in fissures at the time of testing.
Clarity enhancement has become a common practice in trade for many
gemstones. This enhancement is reversible at any time.
