In these jewelry works, the well-cut Fanta stone, like crystal clear fruit hard candy, collides with matching stones or colors, or brings out the best in each other, and each piece has an extremely unique aesthetic feeling.
The little Fanta stone contains great potential, and now its value can rank top3 in a big family like garnet, second only to garnet and sapphire. After seeing this dazzling big-name jewelry, you must also want to continue to follow the footsteps of Gem Jun to learn about Fanta Stone!
Fanta stone, also known as orange garnet, is a kind of manganese-aluminum garnet that reaches the quality level of gem, and it is also a very rare gem. Among the many colors of garnet family, Fanta stone has a warm orange color, which also establishes its irreplaceable position in garnet family.
From the color point of view, Fanta stone is orange garnet, without earthy tones, and the color is bright orange. However, its color clarity is limited by its internal iron content: when the iron content is high, Fanta stone appears orange and brownish red tones; When the iron content is low, Fanta stone appears golden orange. This golden orange is very similar to the color of Fanta beverage, so this variety of garnet is named "Fanta Stone".
The origin of Fanta stone
Like many colorful upstarts, Fanta Stone comes from Africa. 199 1 year, in the Kunene river basin bordering Angola in the northwest of Namibia, it was found that when the sunset put away the last ray of sunshine in this primitive land, there were still some shiny orange-red crystals left here. Because of its unique fiery red orange, it was originally called "Dutch stone". After identification, it is found that this kind of garnet is actually a kind of garnet that people have never seen before, and its brilliance and splendor redefine the concept of jewelry-grade manganese aluminum garnet.
The origin of Fanta stone
Fanta stone is mainly produced in granite and placer. The main producing countries are Brazil, Madagascar, Sri Lanka, Myanmar, Kenya and the United States. It is also distributed in Altai and Gansu in Xinjiang.
Fanta stone from Little Three mine in Ramona, Southern California, USA, with bright color, orange-yellow to yellow-orange, and high saturation, is considered as the representative origin of high-quality Fanta stone. Before the discovery of Fanta stone in Namibia and Nigeria, Fanta stone from this area has been the main source of gem-grade manganese aluminum garnet.
Fanta stone produced in Lundazi, Zambia, a relatively new place of origin, is bright in color and rich in orange, which can be compared with Fanta stone produced in Ramona, USA.
Fe-Ca-Al garnet is similar to Fanta stone in body color and luster. But the refractive index of Fanta stone is high, which is negative on the refractometer. Mn spectrum can be seen under the spectroscope, and a narrow absorption band can be shown in the ultraviolet region. However, the inclusions of Fanta stone are often wavy feathers composed of a large number of water droplets, and the appearance is torn.
The refractive index range of Fe-Ca-Al garnet is1.73-1.75; Some Fe-Ca-Al garnets can show iron spectra at 407nm and 430nm. Fluorescence is usually inert; The "heat wave" effect caused by uneven gem growth is also often seen inside. Therefore, Fanta can be distinguished from Fe-Ca-Al garnet in terms of refractive index, spectrum and inclusion.
1. Look at the color.
Fanta stone is beautiful in orange red and orange yellow, and orange red manganese aluminum garnet is the best variety of red garnet. Generally speaking, the higher the color saturation of Fanta stone, the brighter the better, and the ones without gray clay tones are more expensive.
Look at the size
Like other varieties of garnet, Fanta stone is mostly produced in small particles, and large particles of Fanta stone are very rare. Therefore, the price of Fanta stone in large carats is higher, and it is more worthwhile to start when the economy allows.
View clarity
The defects of natural gemstones often affect their quality, and then affect their prices. The higher the purity of Fanta stone, the less impurities and defects in it, the better the quality and the more expensive it is.
Observation cutting
The choice of Fanta stone also has certain requirements for cutting methods. Fanta stone is suitable for all kinds of faceted cutting shapes: round, oval, triangle, horse eye, teardrop and so on. Cutting Fanta stone into facets of various shapes can fully show the sub-diamond luster with high refractive index. At the same time, different cutting shapes also have an impact on the value of Fanta stone.
