Blue Star Sapphire Ring

This is one of my favorite rings ever. I am not sure if I want to sell it, or keep it. It is a blue star sapphire, of excellent quality. The star is equal, and the legs go all the way to the bottom of the cabachon. It is set in sterling silver, and is a size 6. Star Sapphires can be both natural, enhanced, or synthetic. One of the most famous synthetic star sapphire is the Lindy Star Sapphire. You can tell a Lindy Star from a fraud because it will have a L engraved into the back of the stone. This ring setting has a fancy filigree design to it. This star sapphire was sold to me as natural in color, with no treatments. It is a 7mmx5mm oval. One more way of telling if your star sapphire is synthetic or natural, is if the star stays exactly in the middle and never moves. The star should shift with movement of the gemstone.

Simulated Gemstone vs Synthetic Gemstones

There is a difference between simlated and synthetic gemstones. Of course a natural gemstone is a genuine gemstone.
Simulated gemstones are manmade gemstones, that can be made of any materials, including glass. They mimic the natural gemstone, they are simulating. They are often very large, affordable, clean and quite beautiful. They do not hold a lot of value, but make quite striking jewelry. Probably the most well know simulated gemstone is a CZ, which of course is a simulant for a diamond. Another one that I very much like, is the Paraiba Ice. It is a simulated gemstone made to mimic the very expensive Paraiba Tourmaline, which is the natural form of the gemstone. It has a lovely swimming pool blue color, and is quite affordable, in the simulated form.
Synthetic gemstones, are manmade gemstones as well. However they have the same chemical and optical properties, as a natural gemstone. There are some that carry a great deal of value, and are worth having in a collection. I own some padparadscha sapphire synthetic gemstones. I would of course love to own the natural form, but it is not only extremely rare, but extremely expensive. There are many synthetic stones on the market. It is like having a perfect version of the natural stone, without the expense.
Of course, as a collector, I would love to have a natural gemstone in all the stones that are available. Unfortunately that is not always possible, so these lovely substitutes, do nicely in their place.
