What Is A Black Sapphire?


What Is A Black Sapphire?

Like most people, you’re probably familiar with blue sapphires. But did you know that sapphires actually come in many colors? And that one of those colors is black?

Black sapphires are gaining popularity. So, what is a black sapphire? Are they rare? Expensive? Are they even real sapphires? Do they require special care? Does a black sapphire have any unique meanings?

What Is A Black Sapphire Made Of?

Corundum is a mineral mined in numerous worldwide locations. It’s extremely hard, second only to diamond in hardness. Traditionally, it was used as an abrasive. If you have a very old emery board, you may have filed your nails with finely ground corundum. However, due to its uneven quality, most abrasives now use a synthetic version of corundum.

Corundum is aluminum oxide. When it’s pure, it’s clear and usually transparent. But as it forms, trace amounts of other minerals may be incorporated into its structure. Those are known as impurities, and they are what give gemstones their color. Impurities include chromium, iron, titanium, and vanadium, among others.

So what, you may be thinking. Well, in the world of gems, high-quality corundum is known as a precious gemstone. Corundum that contains chromium is known as rubies. Iron and titanium turn colorless corundum into sapphires. Because the impurities are rarely distributed evenly, no two gemstones, including black sapphires, are identical.

Is A Black Sapphire A Real Sapphire?

Black sapphires are corundum, which, similar to blue sapphires, get their color from iron and titanium. They have all the characteristics of the other colors of sapphires and are genuine sapphires. The biggest difference is the fact that black sapphires are much more abundant than some of the other colors. They’re equally beautiful but far less expensive.

What Does A Black Sapphire Look Like?

Sapphires may be transparent, opaque, or anywhere in between. Some may have inclusions, such as rutile needles. These may create an appearance known in silk. If the rutile is arranged in a specific pattern, a star is visible on the surface of the gem. This is known as asterism

Black sapphires are more often opaque than transparent. The color is very dark. Some may be more very dark blue or gray than black. They are still known as black sapphires to avoid confusion with blue or gray gemstones. Their color means that black sapphires are sometimes mistaken for onyx, a very different gem. 

Like other sapphires, black gems may exhibit pleochroism. That means they show more than one color, depending on the angle from which you view them. Faceting can enhance that display of color. You may see blue flashes in your black sapphire.

What Is A Black Star Sapphire?

Asterism, or stars, occur in black sapphires in a different manner than in other sapphires. Rutile needles form part of the star as it does in other gems. However, black star sapphires also contain hematite and ilmenite. These can create a yellow/golden-colored six-ray star. The rutile makes a white six-ray star along with it but at a different angle. You see a star with 12 rays in the finest specimens. These are extremely rare and extremely expensive.

Black star sapphires are rare and far more valuable than black sapphires. They are mined in countries like Thailand, rather than in Australia, which is the source of most black sapphires. Black star sapphires are cut as cabochons, to display the star, instead of faceted like black sapphires. 

What Are The Differences Between Black Sapphires And Onyx?

Onyx and black sapphires are both very dark gemstones used in all types of jewelry. At first glance, they look the same. And in some instances, a black sapphire is used as a substitute for onyx.

Because black sapphires are so abundant, they are often significantly less expensive than other gems. Onyx typically costs more, especially the rare variety that is solid black. However, onyx is much softer and less durable than sapphire. Care must be taken to avoid scratching it. That’s not an issue with black sapphires, which stand up better during everyday wear. 

Both gems are desirable in their own way. What’s important is that you know which one you’re purchasing.

Is The Color In Black Sapphires Enhanced?

Because people often prefer intense color and perfection, many gemstones are treated to improve their appearance. For example, blue sapphires are frequently heat-treated to deepen the blue. That also burns away specific inclusions that may have impaired the gem’s clarity. 

Diffusion treatment is a special type of heat treatment that enhances and enriches the gemstone’s color. Because the abundance of black sapphires makes them inexpensive, they are seldom subjected to heat treatments. However, the value of black star sapphires means that diffusion treatments may be used to enhance the star. 

As with all gemstones, purchase your black sapphires and star sapphires from reputable dealers. They will disclose any treatments. There’s nothing wrong about buying treated sapphires if you’re making an informed purchase.

Are There Synthetic Black Sapphires?

Even though black sapphires are plentiful and are often considered as low-value gemstones, they are sometimes synthesized. Black star sapphires, because they can be quite valuable, are more commonly synthesized. Your best choice is to buy from a reputable seller. If you have doubts, there are some home tests you can try.

Enlarge It

Synthetic sapphires usually appear flawless. Natural sapphires usually have inclusions or small flaws. If you purchase many gemstones, you may want to invest in a jeweler’s loupe to look for imperfections. 

Breathe On It

Breathe on your black sapphire. Your breath will make a fog, which will clear within one or two seconds. If it takes longer to disappear, you probably have a synthetic.

Scratch It

All genuine sapphires are hard and can only be scratched by something as hard or harder. Try scratching your gem with either a diamond or a sapphire that you know to be real. If you can scratch it, it's synthetic.

Light It Up

Go into a dark room with your sapphire. Shine a light on it. Genuine black sapphires absorb light rather than reflect it. If it’s synthetic, it will probably reflect one or more colors.

Some tests for authenticity can only be done by experts. For example, a genuine black sapphire is magnetic. Impostors typically are not. Other properties of your gem can be measured using specialized instruments. These include specific characteristics such as crystal structure, density, cleavage, and refractive index, among others. While synthetics can mimic at least one of these, they can’t match all the properties of a natural black sapphire. 

Because of their resemblance to more expensive black stones, disreputable sellers may try to substitute black sapphires for them. They then charge a premium price for the inexpensive substitute. As well as onyx, black sapphires may be sold as tanzanite, iolite, or other black gemstones.

In general, it’s a good idea to have your black sapphire and black star sapphire evaluated by an expert to be sure your stone is genuine.

How Should You Care For Your Black Sapphire?

The durability of black sapphires means they don’t need special care or cleaning. Because they can chip or break, protect your gems, especially those mounted in rings, from being struck.

Warm water and a gentle soap are usually all that’s needed to clean black sapphires. An ultrasonic cleaner is safe for untreated gemstones. However, do not put your black star sapphire in an ultrasonic cleaner. 

Consider potential harm to the setting when cleaning. Avoid solvents, such as alcohol, and products such as boric acid. Use a soft toothbrush or artist’s paintbrush to clean detailed areas.
