Clarity<br />
Lighter colours of spinel are usually relatively free of<br />
inclusions. Saturated reds and blues are rare and sometimes<br />
included. Some spinel has interesting inclusions that refl<br />
ect the gem’s octahedral crystal growth. Groups of these<br />
microscopic inclusions can resemble human fi ngerprints.<br />
Treatments<br />
Some spinel may be heat treated to improve clarity, but it is<br />
a stable treatment. In rare cases, spinel may also be fracture<br />
fi lled to improve its apparent clarity.<br />
Sources<br />
Fine large red spinel crystals, historically referred to as<br />
“Balas rubies,” were mined in central and southeast Asia.<br />
Key mining locations are Myanmar (formerly known<br />
as Burma), Tajikistan, Sri Lanka, Vietnam, Tanzania and<br />
Madagascar.<br />
