Corundum in its earth state is colourless, often called white, and although rare, tends to not be expensive because it does not show much brilliance.
Colours, as in many gemstones, are caused by small amounts of impurities Brent Burns Sharks Jersey , usually metal oxides. This is a case where impurity is desirable. Sapphires are identical in all respects to that of a ruby, except the colours found. Chromium oxide causes bright red corundum, which gives ruby. Ferric oxide causes yellow, titanium oxide produces blues.
Pink, yellow, orange Erik Karlsson Sharks Jersey , green and purple are the other colours that are present in sapphire as well as the blue hues, and these are so called fancy sapphires. Also a pinky-orangey version is found that is extremely sought after known as Padparadscha sapphire.
Sapphire Colours
Pink Sapphires - these are much sought after and prized by collectors, and are available in shades from light and bright "hot pink", through to dark "rose". The crimson pink shades can sometimes be mistaken for ruby.
Yellow Sapphire - these are found in shades of dark yellow and light yellow (canary yellows).
Green sapphires - are the least desirable of all sapphires and range in colour from very light green (similar to peridot gemstones) through to darker green shades.
Purple Sapphires - these show a great range of purple shades and are of average value.
Star Sapphires - although found in all shades of blue, they are famed for their unique 6-star affect, known as "asterism".
Change Colour Sapphires - the gem will change colour in different lighting Logan Couture Sharks Jersey , and is known as "pleochroism", similar to that of tanzanite gemstones.
Cornflower Blue Sapphires - commonly regarded as being the most valuable and sought after.
Ceylon Blue - these are sapphires in the pale to middle blue shades. Unless the stone is known to be from Sri Lanka, it would be called "Ceylon-type".
Australian Blue Sapphires - again only if the sapphire is actually from this area should it be called such. These types are usually the darkest available with some showing almost black in colour.
Padparadscha - possibly the most expensive of the sapphires available to purchase today. They are found in quite unique pink-orange tones.
My Summary
At the end of the day, which is the colour that is "best" is really a matter of opinion. If you have a specific budget in mind, try to stick to it.
Although the Padparadscha and Cornflower blue variations usually demand the most money, it does not mean they have to be the best for you. If you like a green Joe Thornton Sharks Jersey , purple or even Australian "black", then that is the one for you.
