What Is Sapphire Crystal?

Sapphire is one of the four precious gems found in the world. It belongs to the same family as Ruby but has a striking blue color, making it very popular. Blue gemstones are rare in nature which is why Sapphire is so sought-after.

This gemstone is the birthstone of September and is aligned with the Taurus star sign. 

It is considered a symbol of wisdom and nobility. Both Holy priests and nobility adorn this beautiful stone because of its religious symbolism.

Sapphires are included in the Corundum family, including another precious gemstone, the Ruby. Emerald belongs to the beryl family, while diamond is a family of its own.

Difference Between Precious And Semi-Precious Stones

Precious stones are distinguished from semi-precious stones, not based on actual price but on the historical perspective. Nevertheless, it is a common misnomer that precious stones are worth more than semi-precious stones.

While it may be true in some cases, it only holds true for some stones. For example, Alexandrite is a striking blue-colored semi-precious stone that is even more expensive than the precious sapphire gemstone that shows a similar color.

There are only four precious stones, i.e., Emerald, Ruby, Sapphire, and Diamond.


The word “Sapphire” is thought to have come from the Greek word “Sappheiros,” which precedes the Latin word “sapphirus,” both of which mean blue.

You can trace the root of the word back to the Sanskrit word “Sanipriya,” meaning “dear to Saturn.”

Sapphire Crystal Appearance

Sapphire is a beautiful gemstone most well known for its striking blue color. However, it also comes in a few other less common colors. They occur in yellow, purple, orange, and green colors.

The cause of the color in Corundum gems is the presence of trace heavy metals in the structure. They replace some of the Aluminum, leading to distinct and beautiful colors.

Types Of Sapphire Crystal

There are five widely accepted varieties of the Sapphire gemstone.

  1. Blue Sapphire: These are classic blue-colored sapphires. They are the most well-recognized and famous sapphire stones in the world. Blue Sapphires come in various hues and shades, the most prized of which is the Kashmiri Sapphire stone. The Kashmir Sapphire is known to be the best-colored blue gemstone; it isn’t even heat-treated.
  2. Cat Sapphire: Non-standard colors of sapphires, such as green, are grouped under Cat sapphires. These are typically less valued than other varieties of Sapphires. Green sapphires are often mistaken for emeralds but are worth more than them because they have fewer inclusions.
  3. Padparadscha: A light orange/pink shade of the sapphire stone is known as Padparadscha. It is a highly valued gemstone only found in Myanmar, Malawi, Madagascar, Sri Lanka, and Tanzania.
  4. Star Sapphire: A sapphire stone that shows chatoyancy is known as a Star Sapphire. These stones are scarce and highly valued due to their uniqueness and optical properties. The largest star sapphire is called “The Star of India” and is kept in the American Museum of Natural History.

Historical Significance

Sapphire gemstones are important stones that are prevalent in human history. They hold great value to a wide variety of people.

  1. Pope Innocent, the third of the Catholic Church, declared that bishops would wear untreated sapphire gemstone rings to symbolize the “holding of secrets.”
  2. Sapphires are the official state gem of Queensland, Australia, because of the prevalence of its mines in this region.
  3. Different cultures around the world held sapphires in high regard and had many beliefs centered around them.
  4. References to Sapphire gemstones are scattered throughout the Bible and were used by priests to signify their relation to heaven.

How To Tell If A Sapphire Crystal Is Real?

  1. Monotony: If you notice that the color of your Sapphire is the same throughout, i.e., it has no variation, then it is likely a fake. Natural Sapphire gemstones refract light in such a way that the color appears to be changing with every angle.
  2. Scratch Test: Sapphire is the third hardest mineral in the world. It is used in high-quality glassware because of this very reason. Sapphire is extremely hard to scratch. You should only be able to leave a mark on it with a diamond or moissanite. If your Sapphire gemstone is easy to scratch, then it is not real.
  3. Acetone Test: To see if the color of your Sapphire gemstone is natural, you should dip it in a solution of acetone and water. If it starts to lose color, then it is artificially colored. Genuine gemstones get their color from their structure, not from paint.
  4. Transparency: You should also look for transparency in your gem. When you hold a natural sapphire up to the light, you should be able to see through it. You should be able to see the light coming through all sides of the stone. In contrast, artificially colored gems are incredibly cloudy.

Sapphire Crystal Value

Sapphire is a costly stone, with prices rising up to hundreds of thousands of dollars per carat. However, they can also be found for only a couple hundred dollars, depending on their quality. This range of value depends on the Four C’s of geology. The gem’s size in carats, the quality of its cut, the clarity of the stone, and the beauty of the color.


The carat weight of a gem is the measurement of its size. One carat is 200 mg or 0.2 grams. The price per carat of a gem increases with its weight. Larger Sapphires are worth significantly more per carat than smaller ones.

This increased price is due to the difficulty of finding large intact stones and the extraction process itself. The three largest sapphires in the world, the star of India, the Blackstar of Queensland, and the star of Adam, are 563, 733, and 1400 carats in size, respectively.

Large sapphires like these go for hundreds of thousands of dollars per carat.


The hardest part of the extraction process is the cutting. Cutting a large, rough stone into a beautiful gem is quite tricky. The cut must be precise to ensure that the stone reflects light correctly and displays its actual color.

Sapphires processed by renowned gemologists and organizations will cost a premium based on the guarantee of the quality of the cut.


Clarity is primarily essential for transparent gems like diamonds. It doesn’t play a significant role in determining the price for colored stones like Sapphires and Rubies. In fact, having inclusions in your colored stone can be a plus if they are just right.

Blue Sapphire gemstones with high clarity are extremely rare and very valuable. Typical sapphires have more than a few inclusions which appear as “needles” or “feathers” in the gemstone.


Color is the most crucial quality that determines the price of a Sapphire crystal. The intensity of the color and its continuity are the major factors in deciding whether it is a good crystal.

The most valuable Sapphire is called the “Kashmir” sapphire. It is regarded as the best-colored blue stone in the world. Experts describe its color to be almost velvety. Kashmir stones are very costly and go for $100,000/Ct at the very least.

Which Gemstones Go Best With Sapphire Crystal?

Sapphires are precious stones and naturally pair best with other precious stones, i.e., diamonds, rubies, and emeralds. 
Sapphire crystal is a very powerful stone, so it goes well with many other stones. It works especially well with rose quartz, aquamarine, and amethyst.

What Is The Rarest Sapphire?

The rarest color of Sapphire is actually pink, which is called Padparadscha. While blue-colored Sapphire isn’t as rare as pink, Blue Kashmir Sapphires are more valuable. They are no longer produced due to the depletion of the mine and are the most expensive form of Sapphire.
Kashmir sapphires are described as having a velvety blue color. They are one of the few forms of sapphires that are not heat-treated at all to enhance their color. The most expensive Kashmir Sapphire was sold in a ring for more than $6.4 million dollars, at almost $250,000 per carat.

Is Sapphire Crystal Heat Treated?

Most sapphires are heat treated for better color and clarity. However, some are not heat-treated. These include metamorphic sapphires from Kashmir, Myanmar, and Sri Lanka.
Sapphires from most other localities are kept in heat treatment plants for hours, days, and sometimes even weeks. Non-treated sapphires require a certificate to be sold and are worth more than similar-looking treated ones.
Heat treatment is an age-old method of bringing out the colors of gemstones. There is evidence of ancient Romans using this method as well. It removes rutile inclusions and improves the color of the stone.
