The Various Types of Sapphires Explained

As mentioned, you get a variety of different types of sapphires. Those who are enthusiasts of this precious stone may or may not know about them. The next time you walk into a jewelry store looking for a Sapphire ring, why not ask them if they have any of these other ones, for something a little more unique and original on your finger.

Blue Sapphire

Deposits of this stone can be found all over the world, from Australia to Cameroon, Colombia, Kenya, India, Malawi, Nigeria, Rwanda, Thailand, Vietnam, and Montana, to name a few places. Both this one and the Ruby are in the same settings, but their geographical formations are different. For example, they can either be corundum or pegmatite. The quality does not depend on where they are found as some places have a higher quality than others. However, the price does depend on it.

In stores, this will depend on a few factors especially color, clarity, cut, size, and overall appeal. With most precious stones, the ones that are not treated and are as close to their natural state, are worth a lot more than the ones that are treated. When buying a stone or jewelry with a supposed original stone, it will often be certified by a relevant authority like the Gem Research Swisslab (GRS) or the American Gemological Laboratories (AGL), which are independent labs and facilities that do all the testing http://gemresearch.ch/

The Blue Sapphire is described in terms of its saturation, tone, and hue which would be the color of the stone. Their evaluation is based on the purity of this blue. 2 other common hues found in them are violet and green. If the gem is of pure color, it is worth a lot more than one which has other hues in it.

Pink Sapphires

These are found in various shades from dark to light pink depending on the amount of chromium present in them. With these, the deeper the color, the higher the value and price paid for them. So, if you are looking for something expensive, go with the one that is the darkest pink. In other words, this would be a ruby or sometimes also called a pink sapphire.

Star Sapphires

"Asterism" refers to the star-like design that most of these types adorn on them, they are referred to as star sapphires because of this. This is often visible when viewed overhead with a single light source and is caused by the way the crystal is structured which forms this six-sided star shape.

The star can come in two colors, a white one and a gold one. During their forming and crystallization thereof, these stars start to take form. Sometimes even misshapen ones form and get a 12-rayed star, which can produce a “cat-eye” effect. The “Star of Adam” is known to be the largest blue star sapphire. One thing to keep in mind is not to establish the quality of the piece by looking at the size. It has more to do with the intensity, color, and the asterism, which is to say the one with the strongest appearance of the star is valued the most. But this is not true.

Padparadscha or The “pink lotus”

Delicate pink-orange hue corundum, that graduates from light to medium, which was originally found in Sri Lanka, has been named the “padparadscha”, which is Sanskrit and translated as “Padma” = lotus, “ranga” = color. Something similar in color to the lotus flower.

If you are in the market for something delicate and feminine, this would possibly be the best option for you or your partner. Imagine having beautiful pink-orange sapphire engagement rings or blue, green, and violet versions adorning your fingers?

Point to take home is that the natural versions are usually prized the highest, but be careful when buying them as more have been seen on the market due to the result not of finding them in nature but of artificial lattice diffusion of beryllium.
