LAPIS LAZULI ADDITIONAL INFORMATION
|
Color
|
The color of Lapis Lazuli is a rich, Royal Blue.
|
|
Sources
|
Afganistan is the primary source of fine Lapis and
has been for Centuries. In fact, the mines were visited as early as the
twelfth Century by Marco Polo on his journies to China.
|
|
Treatment
|
Fine Lapis requires no treatment. Some, however
require a blue dye to cover any white calcite present.
|
|
Care
|
Lapis Lazuli is not a hard gemstone and easily
loses its polish if subjected to any abrasion. For this reason Lapis should be
mounted in a well protected setting.
|
|
Lore
|
Lapis has been ground up to produce the rich Royal
Blue paint used by great painters for their portraits of Royalty.
|
|
Uses
|
Lapis is used for beads, pendants and well
protected men's rings.
|
|
Value
|
Fine, rich blue, natural Lapis is moderately
expensive. An even distribution of gold flecks of pyrite adds value.
