Once a secret of mineral collectors, kyanite is today an increasingly popular jewelry gemstone. Color is the most important consideration in gemstones and the colors of kyanite cover beautiful blues that have a visual resemblance to superb blue sapphires. Kyanite is very challenging for the lapidary as it has hardness anisotropy, a directional hardness varying between 4 and 7.5, cleavage planes, pleochroism (colors and their intensity change when viewed from different angles) and thin crystals that are often zoned displaying an uneven color, making faceting quality critical. Gem Adventurer’s Kyanite is finished by expert lapidaries who carefully orientate the blade-like crystals in a manner that maximizes brilliance over weight, displaying a fine even color.
Even though kyanite was named in 1789 from the Greek 'kyanos', meaning 'blue', it was sold to Europeans as blue sapphire until the turn of the 20th century and interestingly, is still occasionally found in parcels of sapphires. Normally regarded as a blue gem, kyanite also comes in brown, gray, green, orange and white. Similar to sapphire, kyanite's blues are caused by iron and titanium, hence the visual similarities.
While kyanite is found in many countries, it is extremely difficult to find evenly colored crystals with a good clarity. Blue kyanite's most famed origin is Nepal's Kali Gandaki region, whose deposits were discovered in 1995. Mining at this remote location is difficult, impacting yield.
Kyanite has a Mohs' Hardness rating of 4.0 - 7.5 and should always be stored carefully to avoid scuffs and scratches. Clean with gentle soap and lukewarm water, scrubbing behind the gem with a very soft toothbrush as necessary. After cleaning, pat dry with a soft towel or chamois cloth.
As gem mines are becoming more and more depleted, gemstones of all types are becoming increasingly sought-after. Whether you are a collector or a first-time buyer, you will be amazed by the timeless glamor loose gems have to offer! They are fun to collect and look spectacular no matter how you display them. You can make an appointment with your jeweler to experience the joy of creating your very own, one-of-a-kind design. Choose from a variety of settings and styles to create a completely unique presentation that's sprung from your own imagination. Or display your loose gems under glass, showcasing rare and vibrant stones in an artistic and sophisticated manner. No matter how they're displayed, loose gemstones are brilliant collectibles for gem lovers and avid collectors alike!
All weights pertaining to gemstones, including diamonds, are minimum weights. Additionally, please note that many gemstones are treated to enhance their beauty. View Gemstone Enhancements and Special Care Requirements for important information.
Cut: Refers to the geometric shape and proportions of a gemstone. A gemstone’s cut is what most directly affects its sparkle or brilliance.
Facet: A flat cut on the surface of a gemstone.
Fire: Flashes of rainbow colors. Also called “dispersion.”
Hardness: Resistance to scratching. The higher the number, the more resistant.
Hue: Another word for color.
Luster: The shininess of a jewel.
Opaque: The opposite of transparent. Light cannot pass through an opaque gemstone, therefore they do not have any sparkle or fire.
Saturation: This term refers to how pure or deep a gemstone’s color is. Some gemstones, like aquamarine, have a naturally low saturation (very light blue) while other gemstones, like amethysts, can have very high saturation (rich, dark purple).
Sparkle: The white light leaving a jewel, traveling upward, which is visible to the eye. Sparkle is often referred to as “brilliance.”
Toughness: Resistance to breakage.
Gemstone Shapes & Cuts
These are the common shapes or cuts for gemstones, each lending a different look and allure.
Baguette: Baguette means “stick” or “rod” in French, which makes it a very appropriate name for this gemstone shape. Diamond baguettes are often used as accent stones to flank a primary stone.
Brilliant: Any gemstone cut with 58 facets, which produces the maximum possible sparkle. A brilliant cut can have several shapes, including round, oval, pear, radiant and heart.
Cabochon: This shape features a rounded, perfectly smooth surface instead of facets. It is the oldest gemstone shape and is commonly used with opaque stones such as opal, jade and turquoise.
Cushion: A very popular style for most of the 19th century, cushion shapes are slightly domed with rounded corners that make the stone look like a pillow. In fact, this shape is often referred to as a “pillow cut.” It looks particularly beautiful in candlelight.
Emerald: With its long, steep facets, emerald cuts tend to flash rather than sparkle.
Fancy: Technically, this term refers to any type of gemstone that isn’t round, but many jewelers reserve it to describe the more exotic gemstone shapes such as marquise, heart, pear and trillion.
Heart: Often described as a custom cut, heart-shaped gemstones are very popular for pendants.
Marquise: According to legend, this shape was commissioned by King Louis XV to resemble the smile of his mistress, Marquise de Pompadour. Ideal marquise cuts have a length to width ratio of 2:1.
Oval: Similar to the round shape, oval gemstones produce a high amount of sparkle and fire.
Pear: This is a classic teardrop shape that is ideal for earrings and pendants.
Princess: This a relatively new shape that combines the sharp, flat edges of an emerald shape with numerous small facets, which produce both sparkle and fire.
Radiant: This shape is similar to emerald, but it adds extra facets on the edges and corners to increase the gemstone’s sparkle.
Round: This classic shape produces maximum sparkle and fire, making it an ideal shape for diamonds.
Tapered Baguette: A tapered baguette is a baguette shape with one end that is narrower than the other.
Trillion: A very striking, usually three-sided shape, trillion gemstones (especially diamonds) are celebrated for the intense fire they produce.
The Mohs Scale
The most common measure of a gemstone's degree of hardness is based on the Mohs Scale. Devised by German geologist Friedrich Mohs in 1812, the Mohs Scale grades minerals on a comparative scale from 1 (very soft) to 10 (very hard).
Hardness is generally associated with durability and the ability to resist breakage. When referring to gemstones, however, hardness more accurately means the stone's ability to resist abrasion. What the scale means is that a mineral of a given hardness rating will scratch other minerals of the same rating, as well as any minerals of a lower hardness rating. For example, rubies and sapphires, which are composed of the mineral corundum and have a Mohs rating of 9, will scratch each other, as well as topaz (rating 8) and quartz (rating 7). But they will not scratch diamonds, which are rated 10 and considered the hardest substance.
The numeric values assigned to each interval of hardness are not equal. Some stones are disproportionately harder than others. Because Mohs Scale wasn't made for exact precision, it uses half numbers for in-between hardness ratings.
Kyanite is a silicate mineral whose name is derived from the Greek word kyanos, meaning blue. This blue mineral can also appear to be white, grey, black or green. It is believed that kyanite will help you understand life lessons and tap into your creative side with art, dance and writing. It is also known to deflect negative energy to bring serenity and inner peace. This stone is thought to be good for communication, mental awareness, meditation, and dream recall.
Due to differing atom concentrations and orientations amongst crystal structures, most gems' hardness rankings can somewhat vary from crystal to crystal within a specific gem classification. Kyanite's identifying characteristic, however, is that it is uniquely anisotropic, which means its hardness often varies widely in the same crystal. For this reason, kyanite ranges 4.5-6.5 on the Mohs Hardness Scale.
As a gemstone, kyanite has been somewhat limited by its varying and unusual hardness ranking. Regardless, it has a lovely appearance when used in jewelry. Notable occurrences include Brazil, Switzerland, Russia, Serbia, India, Kenya, and in the southern United States.
