Cubic Zirconia White AAA
Cubic Zirconia Loose stones – AAA Cubic Zirconia – White CZ – CZ Stones
“Due to its low cost and close visual likeness to diamond, cubic zirconia has remained the most gemologically and economically important diamond simulant since 1976.”- Statistics
Cubic zirconia (CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colourless, but may be made in a variety of different colours.
Loose cubic zirconia stones are generally colorless, but many shades of colors can be added using trace elements during the manufacturing process. Clarity, or clearness, of loose cubic zirconia is a quality factor. The manufacturing process can sometimes cloud a stone, making visible imperfections. Just as with genuine diamonds, the clearer the stone is, the greater the value.
The RF induction coils function in a manner similar to the primary winding in a transformer. This heating method requires the introduction of small pieces of zirconium metal. The temperature is reduced in a controlled and gradual manner, resulting in the formation of flawless columnar crystals that are typically about 5 cm long by 2.5 cm wide, although they may be grown much larger. Prolonged annealing at 1400 °C is then carried out to remove any strain. The annealed crystals are then cut into gemstones.
