Labradorite
Cabochons
|
|
|
Labradorite is a unique and fascinating
mineral. At first glance it may appear to be dark and unremarkable until the
colorful shiller glows on the surface. Labradorite can produce a colorful
play of light across cleavage planes and in sliced sections called
labradorescence. The usually intense colors range from the typical blues and
violets through greens, yellows and oranges. Some rare specimens display all
these colors simultaneously. Light is refracted through layers within the
crystal producing the shiller, which is only seen if viewed from the proper
angle in the proper light.

Lapis Lazuli
Cabochons
Lapis lazuli is prized for
it’s intense blue color. It has been mined in Afghanistan for over 6,000
years. Formed from more than one mineral with the main component of
lazurite. Most lapis lazuli also contains white calcite, blue sodalite and
pyrite. The finest color is intense blue, lightly dusted with small flecks
of golden pyrite. Patches of pyrite help in identifying the stone as genuine
and do not detract from its value. In addition to the Afghan deposits, lapis
has been extracted for years in the Andes, where the deep blue stones rival
the quality of those from Afghanistan. Lesser sources include the Russia,
Siberia, Angola, Burma, Pakistan, California and Colorado, Canada and India.
