Hey there, Fireflies!

It's time to learn about the fabulous Sapphire, September's Birthstone!

Rough Corundum - By Ra'ike (see also Ra'ike on de.wikipedia [GFDL (, CC-BY-SA-3.0 ( or CC BY-SA 2.5  (], via Wikimedia CommonsSapphires are a member of the Corundum Family and come in all the colors of the rainbow - except for red. Each of these gemstones has the same crystalline structure, yet when there are different mineral inclusions/impurities that are trapped inside the gemstone, the color of the gemstone changes drastically. Yet they are all in the same family. When a gemstone has the same crystalline structure that can place it in the Corundum Family yet is characteristically a saturated red, that is when a Sapphire becomes a Ruby. Otherwise, even pink corundum are considered Sapphires. 

Banded SapphireWhen Sapphires are colorless or in any color but blue they are called Fancy Sapphires. Parti-Colored Sapphires are gemstones that have 2 or more colors in the same stone. The marriage of 2 colors can be any mixture, but more commonly the combinations will be different shades of blue, green, yellow, clear, and browns.


Sapphire Engagement RingColorless Sapphires have been traditionally used as a Diamond Alternative for many years, and at a Moh's Hardness of 9 they're extremely durable - and they're more budget conscious than your traditional diamonds, too!


Star SapphireSapphires even cross into the phenomenal gemstone category with Star Sapphires and Star Rubies being highly prized for their internal play of light separating into viewable lines and stars called Asterism. These lines come from a mineral called Rutile that grows in a linear structure inside the Sapphire and lines up at perfect angles to refract light into what looks like the rays of a star that float on the surface of the gemstone. These particular gems are cut into cabochons - gems that are round on top and flat on the back - in order to make the best visibility of the star possible. 

Sapphires also come in a rare form called Color Change. There are different minerals that grow inside each gemstone and some of these impurities react differently with different types of light. Incandescent light is different than Fluorescent Light, as is Natural Daylight. Each light source has a unique wavelength and reacts with our visual environment differently. The gemstone's inclusions change the look of the stone depending on the available light source by absorbing and reflecting the different wavelength of colors back to our eyes, making them look like a different gemstone shade all together! 


Blue SapphireIn the gemstone industry, Sapphires are all generally considered to have been treated in some way unless they have a specific certificate of independent lab testing stating that the gemstone has not displayed any evidence of treatment. Before 1980, and dating back to ancient Roman times, Sapphires were treated to enhance their color and beauty but this treatment was kept a secret and not many consumers were made aware of this issue. In the early 1980's a company that mined Sapphires out of Yogo Montana, USA started marketing a special Sapphire named the Yogo Sapphire that was "the only guaranteed untreated Sapphire in the world", exposing this unknown tidbit of information to the public. By 1982 the Sapphire industry had been completely exposed for it's secret practices of heating/treating Sapphires and by 1984 it was front page news on the Wall Street Journal. Consumers were angry and wanted full disclosure.

Old FurnaceThe oldest treatments involve heating the stones to enhance the color and clarity. Furnaces are used to heat the stones for extended periods of time to a specific temperature, and most use controlled environments with certain air mixtures such as nitrogen-deficient or oxygen-rich. Low heat can change the color of the stone and high heat will change the color and also dissolve the rutile inclusions making the stone look clear and inclusion-free. Diffusion Treatment is a much newer form of treatment but is a common practice where another substance, such as beryllium, is introduced into the stone via high heat to change or enhance the color.

Multicolored SapphiresUnfortunately since the practices of treating the stones has had such a long history and was so embedded into world culture, and the entities doing the treatments have had such a long time to perfect their practices, it can be quite hard to tell when just looking at a stone to know if it has been treated in some way, so the industry just has an umbrella disclaimer that all Sapphires are considered treated unless there is proof that they have not, however if there is treatment that is known and significantly affects the value, it must be disclosed to the consumer. 


Sapphire Boule - Synthetic Sapphire - By WhiteOakTree - Source: WikiCommonsShown here is a synthetic Sapphire, grown in a lab. In 1902 Synthetic Sapphires made their way into the scene, and while the synthetics being created today have a use in industrial applications, some have made their way into the gemstone industry and are so good at mimicking natural Sapphires, they can even fool some of the most trained eyes. It is best to source your Sapphires from reputable dealers and jewelers who are committed to full disclosure and making sure you, the consumer, is informed. Here at Firefly Jewelry Studio you will find that commitment. No synthetic gemstones are used in any of Firefly's Collections and gemstones are only sourced from mines and dealers with the same commitment to excellence and transparency.

The Largest Gem Quality Star Sapphire ever found is the Star of India. Mined in Sri Lanka and procured for the Paris Exposition in 1900, it comes in at a massive 563.4cts. This golf ball sized beauty now lives in the American Museum of Natural History.

It was stolen with several other notable gemstones. The thieves were caught 2 days later and in January of 1965 revealed that the gems were in a bus station locker in order to receive a more lenient sentence.

The second runner up for largest Star Sapphire, the winner until 2015, is the Black Star of Queensland. Found in 1938 in Queensland Australia, this big bad beauty weighs in at 733 carats. 

Discovered by a 12 year old boy, this hunker was used as the family's doorstop until that little boy's father, Harry Spencer, a miner in the Queensland Mining Fields, decided to take a closer look more than 10 years later. Harry Spencer sold the stone in 1947 to Harry Kazanjian for $18,000, which funded a new home for his family. 

Harry Kazanjian eventually cut away for than 400 carats to reveal the beauty inside and the final stone with strong Asterism and brightly contrasting rays. His family's business boomed and the stone was tagged as being a lucky stone for those who possessed it! Over the course of the years the stone was eventually sold and in now in a private collection in Switzerland.
