What Do You Know About Star Sapphire?
Where does its name come from? Is it in the shape of a star?
It's a type of sapphire called a star sapphire because it has a star-like phenomenon called asterism.
Star sapphires have needle-like inclusions that line up with the crystal structure and make them look like a six-rayed "star" when they're lit from above. The mineral rutile, which is mostly made of titanium dioxide, is often found inside.
So, it's not a stone that looks like a star they are just producing a star reflection, the light makes them look like a star.
The star effect does not in itself stays the same. It is made by the movement of light, and it changes when the stone is seen from a different point.
The clarity of star sapphires is a tricky issue. The ideal star sapphire would be completely clear, but the rutile silk that causes the star phenomenon makes sure that every star sapphire is at least partly covered. This is because the rutile silk makes the stars appear. Fine star sapphires must have enough silk to make a bright, well-defined star, but not so much that the stone isn't clear.
No cleavage can be seen in this material. It has a hardness of 9 on the Mohs scale. Star sapphire is made up of aluminum oxide and forms into crystals, which are made up of three pieces.
As a result of star sapphire's superior hardness and durability, it's almost impossible to tell apart from other gems that have the same colors and sparkle.
The most common color of this stone is blue just like the image above. Sapphires can be even more different. The most common color is dark blue, but yellow, green, and pink sapphires can also be found.
The star patterns can be found in all the colors of corundum, but they can also be found in other gemstones. This is rare, but star impurities have been found in garnet, diopside, and spinel stones.
Because it's so hard to find large sapphires, and because large star sapphires are almost impossible to find. People know about it because it's a 1404.49-carat blue star sapphire that weighs a lot.
The stone is called "The Star of Adam," and it was found in the south of Sri Lanka. It is the largest blue star sapphire, and it was found there. Another large blue star sapphire is called the 'Star of Bombay.' This one is 563.4 carats, and it's a blue star sapphire, too. This is the largest black star sapphire. It is called "Black Star of Queensland." At 733 carats, it is the largest black star sapphire that is good enough to be a gem.
Star sapphires are also graded based on the intensity, visibility, and color of the asterism. Sapphires are mostly graded based on their color and weight. If you want to buy a sapphire, make sure that a professional look at this and other important parts of the stone.

Experts created a synthetic type of star sapphire, it is really similar to the original one. Most of the time, you'll see that it looks too good to be true. To identify the real star sapphire, you can follow these steps:
- First, look for flaws in the stone. Stripes or lines of color also appear on the bottom.
- It shows from the top. Natural star sapphires almost always have one or more of these natural flaws, but not all of them.
- It comes through the top. Most natural star sapphires have one or more of these natural flaws, but they don't all have them.
