Sky blue, blue, or greenish-blue, glassy luster, solution parallel {110} incomplete; hardness 5.5~6, relative density 2.44~2.50. Produced in alkaline ejecta rocks.

2,Blue cubicite output

Blue cube, a member of the siderite group of minerals, is a rare gemstone that is mostly symbiotic with other minerals and is rarely produced as a single crystal. It is reported that transparent gem-quality single crystals of blue cube are only found in the Eifel region of Germany, and their grains are usually very small, with those reaching 0.1ct in faceted products being rare. It is mainly produced in alkaline volcanic rocks such as rattlesnake, and is found in France, Italy, Morocco, Germany, the United States and Canada. Gem-quality transparent blue cube with a brilliant blue color is found in the Laacher See area of the Eifel Mountains in Germany, which is unlike any other source.

The rarity of gem-quality blue cube has made it a rare stone that is traded on a carat basis, so it is usually a collector's item of interest, and rarely appears in settings. But recently, its mysterious figure has appeared in the world's top jewelry brands, such as Bauman Landor and Dior, in their high quality custom-made products. There is little research on gem-quality blue squares at home and abroad, and they are easily confused with the more brilliant blue varieties such as sapphire, apatite and tanzanite. At the same time, the unique blue color of blue cube stone is a very good design material, which can add light and color to jewelry design.

There are many kinds of blue stones, such as sapphire, blue spinel, blue cordierite, tanzanite, blue zircon, etc. Very often, when they are the same cut, people can't tell who is who. It is a rare gemstone in the sodium squared group of minerals, found in volcanic rocks, and is generally small in quantity and size. The most important sources are the ancient volcanoes of Germany and Morocco, with small quantities also found in the United States and Afghanistan. The blue squares commonly found on the market are relatively small, ranging from a few minutes to a few tenths of a centimeter. At present, the blue gemstone is worth collecting because of the size of the cornflower or royal blue sapphire, which is not the cobalt crystals, but the difference in color and price is very big. If you have a lot of money, you can also consider the blue diamond.

5,Identification of similar products

Similar to blue diamonds are the lapis lazuli and sapphire, tanzanite, Paraiba tourmaline, "Paraiba" apatite, cobalt-blue spinel and blue glass. The gemmological parameters of lapis lazuli and sodalite are close to those of the blue squares, but they are mostly found in aggregates and single crystals are rare; the other stones are easier to identify from the blue squares by their optical properties, refractive index, hardness, relative density, absorption spectra, UV fluorescence characteristics, etc.
