8 Hearts & 8 Arrows Cut, 10 Hearts & 10 Arrows Cut, Star Cut Machine cut Cubic Zirconia and Synthetic Gemstones wholesale from China Manufacturer and Suppliers Pictures What is Hearts and Arrow Cut? A: Hearts and Arrows diamonds are precision-cut variations of the traditional 57 faceted round brilliant cut. They are cut to "ideal" proportions with good optical symmetry, polish and a specific faceting pattern. When all these factors are present, the result is a repeatable, near perfect pattern of eight symmetrical arrows in the face-up position of the stone (called 'crown') and eight symmetrical hearts when viewed in the table-down position (called 'pavilion'). Perfectly formed Hearts and Arrows patterns with eight hearts AND eight arrows (above, left) are only found in diamonds that meet the American Gem Society Laboratories' "0" Ideal Cut specifications. The IdealScope was invented by Kazumi Okuda in the 1970's, and its later incarnation, the "FireScope," was invented by Ken Shigetomi and Kazumi Okuda in 1984. The first official H & A "EightStar" diamond was cut in 1985 by Kioyishi Higuchi for Japanese businessman and FireScope manufacturer, Takanori Tamura.

What is Cubic Zirconia? A: Cubic Zirconia (or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant and it is a lab made created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most natural gems. Its refractive index is high at 2.15 - 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 - 0.066, exceeding that of diamond (0.044). Cubic Zirconia Gemstones is the best stimulant for the Real diamond, it's beautiful and brilliant for the Jewelry designs. At FU RONG GEMS, you can Buy White and Colored CZ Loose Cubic Zirconia Stones With Quality Grades A to Top Grade Quality AAAAA at Wholesale Direct Factory prices from the Real China Professional Manufacturer and Suppliers. How Loose Cubic Zirconia Quality is Determined? A: There are four main factors that help determine the quality or grade of cubic zirconia. These are carat (or carat weight), clarity, color, and cut. CZ stones are imitation diamonds or simulants and are measured in carat weight. Loose cubic zirconia stones are always heavier than real diamonds. This is because the materials that are used to create the stones are denser. Though loose cubic zirconia stones are generally colorless, many shades of colors can be added using trace elements during the manufacturing process. These colors might include lavender, peridot, pink, violet, champagne, aqua, citrine yellow, and others. Typically, transparent cubic zirconia will be the more valuable, high-end diamond imitation. Colored CZ stones are valued according to the rarity,...

Loose Nano Crystal and Nanosital gemstones wholesale from china supplier and manufacturer. What is Nano Gemstones ? A: Nanosital or Nano Crystal gemstone - is the glass-ceramic material with nano sized (10⁻⁹m) crystals of Spinel in an aluminosilicate glass matrix, which is not special glass and it is not synthetic crystal or mineral - it is their hybrid. This composite material has unique physical and optical properties: Color (homogeneous and even), Density (3-3.3g/cm³), Luster (RI=1.61-1.64); Melting temperature (more than 1650 C°) and high thermal shock resistance make this material ideally compatible with the wax-casting technology. Nanosital or Nano Crystal gemstone are a new type of created gemstone made especially for jewellery. The colour is homogeneous, meaning that if you bought 100 emerald green nano crystal stones, the colour would be exactly the same in every stone. The material has been created with precious metal clay in mind, so any size gem should be kiln safe and blow torch safe with out colour change or damage. Nanosital or Nano Crystal gemstone does not contain any health hazardous contaminants (lead, arsenum, cadmium) Hardness: 7 on Mohs scaleRefractive Index: 1.65-1.7Specific Gravity: 3.5-4Dispersion: 0.015Melting Point: 1700 degrees Celcius It does not change color when heated. Can be used in wax casting. The Main characteristics of Nanosital/Nano Crystal stones: 1.Nano Stone's specific gravity index is very close to that of the most valuable gemstones such as topaz, sapphire, ruby and aquamarine.2.Nano Stone and the optical properties of the most popular color gemstones are almost similar. Nano Stone's main feature is its lack of an unnaturally strong lustre, which is typical of cubic zirconia, wherein the play of colors remains attractive.3.Nano Stone's hardness (7 on Mohs scale) guarantees jewellery durability without the loss of its original look. The Nanosital hardness index (7) is higher than glass...

Brilliance is the flashes of white light exiting the top and sides of a gemstone. The higher the refractive index of a gemstone, the more brilliance the jewel emits. Moissanite's superior refractive index makes Moissanite the most brilliant fine...
