Black gemstones are often opaque and block light traveling through them; they are often cut to show brilliance through facets, where they gleam and shine, instead of the sparkle that most light gemstones display. Black gemstones are usually cut to show off their luster, and depending on the gem, can reflect light brilliantly.

Many black gemstones are known for the inclusions in the stone, which in the instance of a black diamond, is the reason why the gem is so colored. Black Diamonds are never graded for their clarity, instead, they are best chosen for their saturation and color distribution. However, Smokey Quartz varies in gradation from translucent to completely opaque.

Star gemstones include needle-like inclusions that reflect light and create their star-like effect. Black Diopside, also known as the Indian Black Star, or the Black Star of India has a four-pointed cross or star. The Black Sapphire has between 6 to 12 points on the star.

The quality of the Cat’s Eye gemstone can be determined by a strong solid band of light that is silvery-white in color with few inclusions. These are mostly shaped into a cabochon shape to show the brilliance of the optical phenomena inside the stone, the star, or the cat’s eye.

Black Gemstones in Jewelry

Black gems are more popular today than in the past. Historically, Black Gems were associated with mourning and death. Queen Victoria wore a crown adorned with Black Jet for Prince Albert’s funeral. 

It’s now more popular to pair them with rose gold or white metals to create a modern-looking setting. They are popular in rings, necklaces, pendants, and earrings, and are also common in men’s jewelry as well, in cufflinks, rings, and watches, due to the masculine appeal of the black color. The color also pairs well with unisex items.

Tips for Finding a Quality Black Stone


Color should be considered when thinking about gemstones as well. Some stones such as Diopside, Sapphires, and Obsidian can be gray or even brown toned in the Black Gemstone category. Star and Cat’s Eye stones can also reflect this coloring, and as such are not completely black and often reflect light from the center of the stone. 

Black Opal is a black background stone with reflective rainbow-colored inclusions. Black Jade is a Jade with higher levels of iron, creating a darker color, but also has secondary hints of green. Many stones’ values are based on the more solid saturation of the gem.

Grading of Black Gems

As a buyer, you should know that black gemstones are graded differently than light and clear stones. Clarity is replaced with saturation. Consistent, solid color is more highly valued than a mottled color, and overall the color should be consistent throughout the entire stone. 

Color in itself is important, as the gem should be the desired color, not a lighter shade. Inclusions should be few and small, and the stone should be free of chips and cracks. The opacity of the stone should be consistent with the expectation of the stone, however, most black gems are not translucent.

Quality is also important when deciding on your gem. Natural gems that luster without chemicals or treatment are the most valuable, and will be the most costly. A natural gem is of high quality without adding chemicals or radiation treatment in order to bring out the coloration of a stone.

You should know the difference between a lab-created stone and a natural, untreated stone. A natural stone is a stone that has been shaped and polished without chemical treatments to enhance the coloring of the stone. Treatments should be disclosed by the jeweler and can range from coatings to radiation treatments. 

Not all treatments are long-lasting or permanent and can be affected by oils, hand-washing, or simply time. You can also purchase lab-created stones, which will be less valuable but more perfect in appearance. Lab-created gems are also known for their sustainability and environmentally friendly sourcing.  Your jeweler should provide you with documentation of any treatments of your gemstones before you leave the store.


You’ll want to decide if the piece of jewelry will be worn as an everyday piece or for special occasions, and durability is an important consideration when deciding on your stone. Sapphires, Garnets, Diamonds are some of the hardest gemstones, where Black Jet, Black Pearls, and Obsidian are more delicate and better for occasional wear.

Keep in mind the inherent properties of the gemstone you chose and be aware that some gems scratch or chip easily if banged or knocked. Pearls are often coated to protect them and can be easily damaged with body oils, cosmetics, and even perfume.

Shapes of Gemstones

Black Gemstones Buying Guide all the gemstones

Black stones are often cut into cabochons or are faceted to maximize the luster. Cabs or cabochons are shaped and polished to bring out the stone’s natural shine, Star and Cat’s Eye stones are the best examples of this. Cabs can also be polished and sculpted with a design carved into the stone. 

Often, less-quality semi-precious stones are cut into cabochons if they have consistent coloring but are otherwise flawed. Black gemstones can also be cut into any popular gemstone shape, with facets that show off the glimmer and shine of the stone.

These shapes include round, cushion, oval, pear, emerald, square, brilliant, princess, baguette, octagon, or marquise. The beauty of opaque stones shows in the sparkle of the facets of these cuts, and in the luster of the stone itself.

Create your own piece

To create your own piece, find a jeweler that offers loose gemstones, you can mix and match them with settings to create your own unique personalized ring. However, you may also prefer to buy a finished jewelry item depending on the need and use expected out of your jewelry piece.
