Whilst today's main sources of Sapphire are Africa, Australia, Myanmar (Burma),
Sri Lanka (Ceylon), Thailand and the United States (Montana, North Carolina), there
are also known Sapphire deposits in Brazil, Cambodia, India, Madagascar, Tanzania
and Vietnam.

Myanmar (Burma), and Sri Lanka (Ceylon). Sapphires from India and Myanmar (Burma),
are highly prized for their pure blue colors and stones from these regions are priced
accordingly, often at collectors prices, particularly if there is documentation
available to prove the origin of the Sapphire. Sri Lankan (Ceylon) Sapphires are

Diamond in this regard. Sapphires therefore are perfectly suited to all jewelry purposes / uses and is a very hard-wearing, durable and versatile gemstone

gemstone. Sapphire is however actually much more than just a blue gem and is found
in various colors including, black, blues, browns, colorless, pink, orange, peach,
purple, violet, white and yellow. Lighter in color than the Ruby, Pink Sapphires
can range from a pale baby pink, to the more valuable bright hot pink, The best
Pink Sapphires should be uniform in color with no secondary overtones such as brown
or lavender.
When buying Sapphires, color, clarity and size are the main considerations and those
that have the most effect upon overall worth. Pay particular attention to color
- look for a stone that displays intense, uniform coloration with no overtones or
secondary colors. The purer the color, the more valuable the Sapphire is considered.
Common Cuts:
Being an extremely hard gemstone that is very well-suited to jewelry purposes, Sapphires
are cut
into almost all of the known gemstone cuts, with Cushion, Emerald, Pear and Oval
cuts being particularly popular.
Routine Enhancements:
Almost all Sapphires found on the market today have been heat-treated in order to
intensify color and remove “silk”, small inclusions present in most natural Sapphires.
This method of treatment is considered permanent and color should
not fade over time.
Care & Cleaning:
Sapphires are a very tough, durable gemstone and can safely be cleaned
with
soapy water or commercial solvent and a brush, and can also safely be cleaned
using most modern mechanical cleaners. Do however avoid subjecting Sapphires
to prolonged exposure
to strong heat or light sources, particularly with regard
to heat-treated gems, as prolonged exposure may cause permanent changes in coloration.
