September Birthstone: What is a Sapphire?

what is Sapphire

The Latin and Greek words sapphires and sapphires, respectively, meaning blue, are the origins of sapphire. It is the traditional as well as modern birthstone of September. The mineral corundum comes in a gemstone-quality variety called sapphire. Although sapphires are often associated with the color blue, the corundum material also appears in other hues referred to as fancy sapphires. The color of fancy sapphires can range from yellow to pink to green, but never red. Rubies are another name for red sapphires. The ruby was traditionally believed to be a distinctively different gemstone, but current techniques have shown that it is the red kind of corundum or sapphire!

Rutile needle-like inclusions, which reduce the gem’s clarity, are typical in sapphires. Except when those inclusions create an asterism, which is a star-like pattern, the sapphires with the fewest inclusions are the most precious. Although some sapphires have been found with 12-pointed stars, asteroids typically appear as six-pointed stars. While transparent sapphires are cut to exhibit their glitter, asterism sapphires are often polished in cabochon to display the star.

Sapphires are excellent gemstones for jewelry because of their durability. However, many sapphires sold in high-end jewelry shops are made synthetically. Since 1902, lab sapphires have been produced, and they are so excellent that only a trained eye can tell the difference, but the vast price difference will give you a hint! Natural translucent sapphires are typically smaller than 2 carats; however, in 2012 a large 1404-carat rare star sapphire was discovered in Sri Lanka! The enormous jewel was worth $300 million US.

Color of Sapphire

Although the gemstone can range from greenish-blue to violet-blue, its remarkable pure-blue hue makes it the most well-known. “Fancy sapphires” are gemstones of the same corundum family as the ruby that come in violet, green, yellow, orange, pink, and purple. Depending on the illumination, some display chromatic variations.

Although corundum is colorless by nature, traces of metals like iron, titanium, and chromium can cause a variety of colors. All corundum gems other than red corundum (rubies) are classified as sapphires. The sapphire’s blue hue is caused by iron and titanium; the more iron there is, the deeper the sapphire’s blue shade will be. While pink sapphires result from significant quantities of chromium, yellow and orange sapphires are colored by iron and chromium. All three trace components are combined to create the color purple.

Brief History of Sapphire

British adventurer Sir Richard Francis Burton is reported to have traveled carrying a talisman made from a sizable star sapphire. The stone brings luck to everyone who looks at it. The Princess Diana engagement ring, at 12 carats, contains one of the most well-known sapphires. The ring was passed down to Prince William, who then gave it to his wife, the Duchess of Cambridge Kate Middleton.

The 62-carat Rockefeller Sapphire is another well-known sapphire. Another well-known gemstone on display at the Smithsonian is the Logan Blue Sapphire. In addition to being the diamond presented for a 5th and 45th wedding anniversary, sapphire is the birthstone for September.

Where is Sapphire Found?

For the September birthstone, three historically significant places are Kashmir, Myanmar (formerly Burma), and Sri Lanka. Along with other nations in Asia and Africa, significant amounts of the September birthstone have also been discovered in Australia, Thailand, Cambodia, Madagascar, and the United States (Montana).

Around 1881, a landslip in the Himalayas uncovered a sizable pocket of velvety ‘cornflower’ blue crystals, which led to the discovery of sapphires in Kashmir. The Maharaja of Kashmir and his troops seized control of the new location as the stunning sapphires spread further south. Numerous thousands of enormously gorgeous crystals were found between 1882 and 1887. The gemstones cut from these crystals gave Kashmir sapphire its status as one of the most sought-after gems in the world. Since then, there has been a sporadic production, yet beautiful Kashmir sapphire jewelry still periodically appears on the auction market.

Another region renowned for producing the birthstone for September is the Mogok region of Myanmar. Dramatic slopes are covered in jungle and surrounded by mountains. Ruby deposits also frequently contain sapphire, though in far lesser amounts than the red stone. The “Burmese” sapphire, as it is still commonly known, can have a deep, intense blue color, making it especially valuable. Jadeite jade, spinel, zircon, amethyst, peridot, and other precious gem minerals are well-known to come from Myanmar.

The birthstone for September has been produced in Sri Lanka for over 2,000 years. The blue and fancy-colored stones extracted from the alluvial gravels of this “jewel box of the Indian Ocean” can exhibit excellent saturation and brilliance. The island’s milky white “geuda” sapphires can also be heated to a deep blue hue.

Thailand is a significant location for cutting and treating sapphire. In the province of Chanthaburi, sapphire miners work in the deep jungle crisscrossed by dirt roads. Sapphires from Myanmar and Cambodia are frequently brought to Bangkok, a significant gem hub, and Chanthaburi for cutting and treatment.
