Cubic zirconia (CZ) is the finest simulated diamond on today's market; like diamonds, cubic zirconia is colorless and do not lose their brilliance. CZ offers a combined high value of refractive index, dispersion and hardness. Cubic zirconia are chemically comprised of zirconium oxide and yttrium oxide. Similar to natural stones, CZs vary in color, clarity and cut. Cubic Zirconia stones are cut in the same way diamonds are cut. The sizing of the gemstone is usually indicated by its weight in carats, a carat being one-fifth of a gram. Because the cubic zirconia is so dense and solid, it outweighs a diamond of the same millimeter size, weighing 1.7 times more than a diamond of the same millimeter diameter. We use the CZ weight in MBM copy, not the equivalent diamond weight. The best simulated diamond on today's market, the Pure Brilliance cuts are truly a cut above the rest – the exact symmetry and proportions of the cuts maximize brilliance. Cubic zirconia (CZ) offers a combined high value of refractive index, dispersion and hardness ( Mohs hardness: 8.5; refractive index: 2.15; specific gravity: 5.8). Like natural stones, CZs vary in color, clarity and cut..
Cubic zirconia vs. diamonds
Overall, cubic zirconia is less expensive jewelry and manufactured, where a diamond is a naturally occurring substance that is very expensive. There are some ways to distinguish cubic zirconia from a diamond as follows:
Thermal conductivity: Diamonds are thermal conductors while cubic zirconia is a thermal insulator. This is what makes the diamond stand out next to the cubic zirconia with special instruments.
Hardness: Diamond has a rating of 10 and Cubic zirconia has an 8 on the Mohs hardness scale.
Density: Cubic zirconia is 1.7 times denser than a diamond.
Refractive index: Diamond has a refractive index of 2.42 vs. Cubic Zirconia has an index of 2.15-2.18
Cut: Diamonds are typically cut differently than cubic zirconia gemstones.
Dispersion: Diamond 0.044 vs. cubic zirconia 0.058-0.066
Color: Cubic zirconia is equivalent to the perfect “D” on diamond’s grading scale but it also comes in other colors as well, such as green, orange and pink, etc. Most diamonds on the other hand have a brown or yellow tinge to them, and only the rarest are truly colorless with diamonds.
Fine-cut crystal from luxury brand Swarovski. Swarovski crystals(called "Swarovski Elements"), the son of a glass faceter, developed in 1892. He mechanized technique for faceting glass crystals, creating a sparkling, diamond-like "chaton". rhinestones and other glass items are highly valued and used in both jewellery and figurines.
Transparent glass material that may be used as beads or in a setting. Crystal jewellery may be colourless or coloured.
Cut, buffed, and sometimes dyed nacreous portions of mollusc shells. Variations and alternate names include coque de perle (from nautilus shells), mother-of-pearl pearl (from mother-of-pearl), and hinge pearl (from the hinge of bivalve shells). Also, the pherical shell core coated with pearlescent material is a shell pearl.
Pearls are produced by oysters. Cultured pearls are still authentic pearls, however humans assist in the process by implanting the 'irritant' (a 'Mother-of-Pearl') into the oyster causing the pearl sac to form and eventually a pearl is created.
A semi-precious material with a banded, layered structure. It varies in colour but onyx stones in jewelry are often black and white.
Very small accessories or ornaments that may be added to a bracelet or necklace. Charms may be purely decorative or of personal significance to the owner.Pandora Jewelry is what the company is known for charms and beads.
Small smooth objects that are designed to be threaded together to create jewellery items, especially necklaces and bracelets. Beads may be made from a range of materials, including glass, ceramic and plastic.
Synthetic stones are man-made, but having the same physical, chemical and optical characteristics as the natural stone. Synthetic stones are made in laboratories; these stones generally lack imperfections.
Genuine Natural Stone
Genuine natural stones are any gemstones that may be used as a jewel when cut and polished and are valued for their beauty but which are not one of the four "precious stones" (emerald diamond ruby or sapphire).
Some examples of semi-precious stones are amethyst, aventurine, carnelian, garnet, opal, peridot, rose, quartz, etc.
Epoxy is tough resistant thermosetting synthetic resins containing epoxy groups: used in surface coatings, laminates, and adhesives.
