What’s Cubic Zirconia? Loose cubic zirconia ( also called CZ stones ) are lab made gems. Cubic zirconia is present in nature, but it is highly rare and the chemical properties of natural cubic zirconia are subtley different than those of manmade gems. Diamonds rate ten on the Mohs scale of toughness ( the highest rating ), while cubic zirconia is often rated at 8.5 on the toughness scale. CZ stones are denser and so heavier than diamonds. When it comes to quality these artificial gems jump before the pack. While most diamonds have what are called inclusions ( failings ), the best cubic zirconia stones are exemplary. Cubic zirconia AAAAA are the highest quality simulated stones, while CZ AAA are next, followed by the A-grade cubic zirconia.
Are Cubic Zirconia Stones Available in the Same Cuts as Diamonds? Cubic zirconia stones are cut so they have the same angles and proportions as diamonds. The most classic cut of both diamonds and CZ stones is the round brilliant, with 58 sides and the power to reflect light. A pear formed cut resembles a teardrop mixes the faceted brilliant cut of a round stone with the lengthened look of a marquis stone.
A square cut is frequently called a princess cut, and has pointed corners. CZ stones are used in engagement rings, marriage bands, earrings, bracelets, pendants, necklaces, solitaire rings, and even ankle bracelets. Coloured cubic zirconia is also used in a selection of fashion jewelry, including earrings and as side stones in rings. Settings are usually made from 14-karat gold, 18-karat gold, sterling silver, or platinum.
