• An extremely fine color 8 1/2 carat Moonstone. Origin: India.

• At one time, Sri Lanka (Meetiyagoda) produced the finest quality moonstone in the world, but production stopped in 1987. India continues to mine today and a fraction of a percent rival the very best Sri Lankan stones.
The Indian stones are considered the best stones available today. The third and largest source is Africa, but almost all of the African production has a yellowish skin color.

• "Gem" quality moonstones will display a crystal clear body with a very strong blue-white opalescence (adularescence) floating across their surface. Commercial stones have a strong 'whole' milk white body color (possibly brown secondary), poorer clarity (stress marks) and semi-blue or silver-white sheen. Gem quality sizes over 5cts are rare and more than 10ct command strong premiums.

• A second variety of moonstone is produced in India. They are called "Rainbow moonstones" Gem quality "Rainbows" have the same body color as the "Blue" moonstone, but instead of a blue-white sheen, they will display a multicolored adularescense. The finest "gems" of this variety have a reddish orange or occasional lavender color with blue and green. Some people call the Blue moonstone Rainbow, but true Rainbow are more costly.

• The stone above is extremely fine, slightly less than 'gem', quality. The body color is a light silver-white skim milk color. The clarity is very lightly included with a single small veil toward the back corner. Almost loupe clean. The sheen (power) is medium strong blue-white. The stone has very good proportions and ideal 8ct size.

• Moonstone should be worn with care. The hardness is 6-6.5 on the Mohs scale and often have strong cleavage.
• Price: $350
