Honing refers to a set of stones (sticks) assembled on the honing head put pressure on the work-Piece along the radial, and through rotating and moving back and forth for precision honing machine. When honing high hardness and toughness materials, the Diamond /CBN Efficiency of honing stone( stick) is 3-75 times higher than that of ordinary abrasive stone, and the honing efficiency of ordinary materials is also improved about 10 times. since Diamond/CBN honing stone (stick) wear is less, the shape retention is better, therefore, the higher honing accuracy and economic effect can be obtained. Diamond honing stick is used to process hard and brittle materials, such as honing high carbon steel, cast iron, cemented, carbide, etc. honing stick mainly used for honing high strength alloy steel, tool steel, stainless steel heat-resistant alloy steel. Customized is OK
In the gem world, all kinds of gem-quality corundum other than ruby are called sapphire. The mineral name of sapphire is corundum, which belongs to the corundum group of minerals. In fact, the gem-quality corundum in nature is called sapphire, or colored sapphire, except for red called ruby, and other colors such as blue, light blue, green, yellow, gray, colorless, etc. Sapphire is preceded by a color name, such as pink sapphire. The chemical composition of sapphire (Al2O3) is mainly Fe, Ti, and color. Corundum contains iron (Fe) and titanium (Ti) and other trace elements, and presents blue, sky blue, light blue and other colors, among which the royal blue and cornflower colors that are considered to be thick but not black are the best. In cabochon cutting, when the interior is rich in three groups of inclusions parallel to the bottom surface and oriented, it can produce beautiful six-shot starlight, which is called star sapphire The composition of sapphire is alumina, which is blue due to the trace elements titanium (Ti4) or iron (Fe2). It belongs to the trigonal crystal system, and the crystal form is often cylindrical, short column, plate, etc., and the geometry is mostly granular or dense block. Transparent to translucent, vitreous luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous body. Sometimes it has a special optical effect - the star effect. The hardness is 9, and the density is 3.95-4.1 g/cm3. No cleavage, fissure development. Industrial sapphire is a material used in special vehicles as transparent armor, and with the exception of diamonds, sapphire is harder than any other natural material. Sapphire belongs to the trigonal crystal system and has a hexagonal structure. The lattice constants are: a=b=4.758A, c=12.991A Refractive index 1.762-1.770 Birefringence: 0.008- 0.010 Uniaxial crystal negative light, in some cases abnormal biaxial crystal light Luster: bright glass luster to adamantine luster Pleochroism: Colored sapphires have dichroism, generally, dark blue/blue, blue/light blue, blue-green, blue-gray, yellow sapphire has golden/yellow, orange/light yellow, light yellow/ Colorless, wait.

As for luminous gemstone, it is man-made gemstone, which is made from quartz (ceramic) and photoluminescent pigment. It can absorb light and glow in the dark for several hours. based on afterglow color, there is mainly yellow-green and blue-green color. we can provide diameter 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 20mm, 22mm. All above have a hole in the bead center. more bigger diameter, such as 30mm, 40mm, 50mm can also be produced, but there is no hole in the center. the price is different with various diameter . As usual, we provide the product with single bead, you can make a string bracelet yourself. If you want a bracelet directly, please inform us the diameter and how many beads you need in a string bracelet so that we can quote you.
