Sapphires are perhaps the most sought after blue stones around. Apart from their obvious value as a precious stone, sapphires are also highly valued in astrological circles as well where they are thought to be the most powerful of all the gemstones. Of course possessing a Sapphire pendant on a necklace can really look stunning as will a blue sapphire ring, however if you are planning to buy sapphire online then you should know a few things so that you can make an informed buying decision.

Sapphires belong to the corundum family of stones which also includes ruby. Since the mineral corundum ranks an impressive 8 on the Mohs Scale for mineral hardness, Sapphires are by their very nature very strong and resistant to scratching, although this does not mean that you can take their safety for granted.

Remember that sapphires which come in a deep “cornflower” blue are the stones which are most highly prized. Some people will also resort to treating lighter varieties of sapphires to high temperatures to get the desired colors, although this is not always the case.

Some sapphires will also exhibit a phenomenon known as Asterism. In such sapphires 6 sometimes 12 lines can be seen propagating from a central point. This is caused by the presence of tiny rutile needles within the sapphires. Again, such sapphires are also highly prized and the more the number of lines they display, the pricier they become.

When buying sapphires online make sure that you have learnt as much as you need to, to make a good decision. If you find the information lacking then you can always ask the vendor by sending them an email.
