Indeed, the diamond is the hardest of all natural minerals. Diamond's extraordinary luster and dispersion give it an exceptional and fiery brilliance, which, when combined with Diamond's extreme hardness, accounts for it's popularity throughout the ages. The best color for Diamonds is no color; or "colorless". It is rare fo Diamonds to be created in colors such as blue, green, yellow and so forth. Such colored Diamonds are know as "fancies". Ideally, Diamonds should be as "clean" of inclusions as possible under 10 power magnification. Cut - especially the proportions - is particularly important in Diamonds to ensure the maximum light return through the crown of the stone.
SAPPHIRE
Many and varied are the myths and folklore that Sapphires have been attributed with over the centuries. These include acting as an antidote to poison and snake bites, protecting the wearer from envy and being credited with numerous medicinal properties.
The main attraction of Sapphire is of course the richness and the beauty of the range of colors that it can be found in. The mineral name for Sapphire is Corundum, which is the next hardest mineral to Diamond. Its hardness ensures that the Sapphire also exhibits a high luster and brilliance after cutting and polishing.
Saphires come in all different colors, including blue, pink, colorless and yellow or orange. Red Corundum is called Ruby (see below). The most popular color of Sapphire is blue. Look for an intense "silky" violet-blue. A rather loosely used trade term - not a technical color description - you may come across is "Cornflower blue". This is rather subjective term used to describe the best possible color. Avoid the very dark and extremely light colored Sapphires, as these are generally low-grade. Clarity is less important than in diamonds, but the cleaner the stone, the better.
Thailand is a plentiful source of Sapphires, and is recommended if you are looking for a very good value purchase.
RUBY
Ruby, the "Lord of the Gems" was once thought to shine through clothing and make water boil. Burmese warriors of old inserted Rubies under their skin in the belief that this would prevent being wounded in battle. Today it is the most popular of all the colored stones, no doubt because of its rich and spectacular beauty.
The most sought after color for Ruby is a bright intense red, although the shade of color is of course a matter of personal preference. The best color is referred to jewelers as "Pigeon Blood" red (another non-technical, rather subjective term). Ruby's colors may range from pink to purplish, and of course a medium tone is preferable: not too dark and not too light. Dark stones tend to look rather muddy, and a light tone gives a washed-out appearance. As with Sapphires, there will generally be inclusions present. These are acceptable, but the less the better!
Rubies are mined in abundance in Thailand, and there is a vast selection to choose from. Another highly recommended purchase!
