This gem, a pink to purple type of spodumene, can show gentle or vivid colours that purchasers seek. However, kunzite fractures easily and is heat sensitive, making it primarily a collector's stone. Despite its scarcity, kunzite is widely accessible in big sizes at reasonable costs. This makes it a popular luxury gift item.
In addition to being beautiful, spodumene crystals are useful as filters for liquids and gases. They remove harmful contaminants from water by means of precipitation or absorption into their porous structure. Kunzite is used in scientific instruments as a filter for gases and liquids. The name "kunzite" comes from the German word "kunst", which means "art".
There are many varieties of spodumene but only one variety of kunzite. That means if you find a nice-looking spodumene crystal, it probably has the same composition as kunzite and will change colour with heat treatment. Spodumene can be white, yellow, orange, red, brown, black, or even green or blue depending on the amount of iron present. Kunzite is always pink or purplish in colour.
Spodumene is found mainly in Canada, USA, Russia, and Australia. Kunzite is found only in America.
The rarity of kunzite makes it valuable as a gemstone.
Kunzite is a well-known gemstone with a lovely lilac tint that celebrates subtle color subtleties. Kunzite is a pinkish-purple to violet-purple type of spodumene. It was first discovered in 1872 in the Kunzite Mountain mine near Lead, SD.
Spodumene is a rare mineral with a formula of (Na,Ca)2(Mg,Fe)5Si8O22(OH)4. It is a member of the orthoclase family and forms long chains of plates that can be flat or slightly curved. The chain structure is stabilized by oxygen anions which connect the chains together. Spodumene comes in many different colors, but usually has a pale lilac tone to it. It was first found in South Dakota and can also be found in Canada, Arizona, and Nevada.
People have been mining for spodumene since 1872 but it wasn't until much later that it became popular as a gemstone. The color change that occurs when exposed to air makes it more attractive than other types of silica. Also, its resemblance to lapis lazuli gives rise to its name (Latin for "like blue").
Although spodumene isn't as hard as quartz, it can still be scratched like a glass.
The most valuable kyanite stones are dark blue in hue, with a luminous transparency and a consistent blue tint throughout the stone that demonstrates visual depth. Because of the difficulty in cutting this type of gemstone due to its cleavage features, a quality or custom cut kyanite gemstone will command a significantly higher price. Smaller beads made from lower-quality material can be used as pendants or earrings while larger cuts can be mounted on rings.
Dark green, red, brown, or black colored kyanite are also valued but are less common. The color variation within a single source rock makes color differentiation difficult so these variations may have originated from different locations within the rock.
Blue kyanite is the most valuable variety of the mineral because it contains more iron than other colors. Blue kyanite is rare and expensive because it requires very specific conditions for formation - extremely low levels of copper and zinc along with high concentrations of iron. These minerals inhibit the growth of crystals and cause kyanite to exhibit a transparent blue color instead.
Kyanite is used by some Native Americans in jewelry because it is soft and easy to work with. They make necklaces out of bundles of kyanite fibers that they tie together with leather straps. The Navajo use orange and white kyanite to accentuate traditional designs.
In conclusion, blue kyanite is the most valuable variety of the mineral because it contains more iron than other colors.
The most precious tanzanite gems are those with a strong-to-vivid blue, purplish blue, or violetish blue tint. These gems can be very small indeed! The rarest and most expensive tanzanite is ABERRANT, which has an intense indigo color that some sources claim is actually a form of purple. It weighs over 3 grams (0.11 oz), is at least 5.5 inches (14 cm) long, and has been valued at $750,000 to $1 million.
Aberrant tanzanite was discovered in 1971 by John Hill in the Argyle Mining District near Vancouver, Canada. He was looking for gold when he found the gemstone, which is why it's also called "golden stone". Aberrants are extremely rare: only about 100 examples have been recorded in the world. They're kept in the British Museum and the Smithsonian Institution in Washington, D.C.
Tanzanite is usually white or pale pink, but it can also be yellow, red, olive green, brown, black, or gray. The deeper the color, the more abundant the element niobium is in the stone.
