Blue Star Sapphire Jewelry

Sapphires are the birthstone for the month of September. Blue sapphire jewelry is traditionally given for the 5th and 45th wedding anniversary. The blue sapphire is one of nature’s most precious gemstones. Blue star sapphires are the ones that have been left in their natural state and are not heated. Because of the star you can see in the stones the ancients believed them to be a good gemstone to have for guidance when traveling or seeking out things.

Blue star sapphire jewelry is very much sought after by women from all over the world. Blue star sapphire rings for men are also very popular. The star sapphires are not heated like other sapphires and when cut in rounds and ovals you will be able to see a 6 ray star-shape in the stone which is a reflection of the light. The heat treated sapphires are a darker, deeper, clearer blue than star sapphires which tend to be more on the blue gray side. All blue sapphires are actually the blue variety of the mineral corundum, formed from aluminum oxide. On the Moh’s scale they are a 9, which is a very hard stone. They come in a variety of shades and hues of blue. There are other sapphire colors too, but the blue sapphires are the most recognizable and most popular ones with the general public.

Sapphires come from deposits found in Thailand, Madagascar, Eastern Australia, East Africa, U.S. and Sri Lanka. These stones make beautiful blue star sapphire jewelry in all kinds of designs and styles. You can still find blue star sapphire rings, earrings, bracelets, pendants and necklaces. However, the star sapphires are becoming rare now since most sapphires are being heated and cut into facets by jewelry designers. In fact, 99% of them are heat treated now. The 6 ray stars that you can see in star sapphires are in the stones that are cut into rounded shapes called ‘cabochons.’ The round cut enables you to see the asterisms. The asterisms are caused by inclusions of the mineral “rutile” in the sapphires. The name star sapphire is associated with being able to see these asterisms in the stones.

The value of blue star sapphire jewelry is judged by the sharpness of the star and the evenness of the rays in the asterisms as well as the body color of the sapphire itself. It is very rare to find star sapphire jewelry that is bright blue in color with a sharp star in it. These pieces are also one of the most prized as well as the most expensive pieces on the market.

When shopping for blue star sapphires keep in mind that they will be in the shape of rounds or ovals. The round shapes are usually more expensive. These stones, like diamonds, are also graded by carat weight. A created sapphire is not a natural star sapphire and is probably just glass so beware of the word “created” when shopping for genuine blue star sapphire jewelry. Also, be prepared to pay more for jewelry that has asterisms that are clearly seen. You can ask to look at the jewelry under a microscope or jewelers loupe to see the inclusions in the stones. If the inclusion is very deep and reaches almost to the surface you will want to avoid that particular jewelry piece because the stones will be easily split open if knocked against something hard. These sapphires look spectacular in jewelry, especially when set with white gold, platinum or sterling silver. Expect to find small stones in the jewelry. It is very rare to find star sapphire jewelry with very large stones. When you buy star sapphire jewelry on the internet and even in local shops be sure that the retailer has a return policy and provides a certificate of authenticity. This will assure you that the jewelry is real and is worth the price you are paying for it.
