At DeCarbz, we believe in not just offering exquisite diamonds, but also in sharing knowledge and insights to empower our customers. In this spirit, we delve into the fascinating world of diamond simulants, focusing on one of the most popular alternatives: Cubic Zirconia (CZ). Understanding CZ: CZ emerged in the late 1970s as a groundbreaking diamond simulant. Created through a meticulous process involving powdered zirconium oxide, CZ crystals are renowned for their striking resemblance to diamonds. However, beneath their surface lies a world of differences in chemical composition, crystal structure, and optical properties. Properties of CZ: With a Mohs hardness of 8.5, CZ boasts impressive durability, although slightly lower than that of diamonds. Typically, colourless and featuring high clarity, CZ stones can be manipulated to mimic a wide array of gemstone colours, making them versatile options for jewellery design. Identifying CZ: While CZ may visually mimic diamonds, there are subtle indicators that distinguish them. One such clue is the presence of non-sharp facet edges, as depicted in the accompanying image. Unlike diamonds, which exhibit precisely oriented and proportioned facets, CZ crystals often display a domed octahedral shape with rounded edges, hinting at their synthetic origin. Simple Tests for CZ Identification: Several straightforward tests can help discern CZ from genuine diamonds: Weight Test: CZ stones typically weigh approximately 1.7 times as much as diamonds of similar dimensions. Fog Test: CZ retains fog for longer durations compared to diamonds due to differences in thermal conductivity. Newsprint Test: Placing the stone upside down on printed text reveals variances in refractivity, with CZ allowing clearer visibility of the text. Additional Clues: Metal Setting: CZ stones are commonly set in base metal, gold-plated, or silver settings, whereas genuine diamonds are often set in precious metals like 14K or 18K gold. Inclusions and Abrasions: A lack of visible inclusions or facet junctions, along with rounded facet edges or noticeable abrasions, may indicate CZ rather than genuine diamonds. Seeking Expert Guidance: When in doubt, consulting a reputable jeweller or gemmologist is invaluable. Advanced laboratory grading techniques can provide definitive identification of CZ and genuine diamonds, ensuring confidence in your diamond selection. Conclusion: As purveyors of fine diamonds, we at DeCarbz are committed to not only offering exquisite pieces but also to sharing knowledge and insights to enhance your understanding of diamonds and their alternatives. By arming yourself with information and seeking expert guidance, you can make informed decisions and confidently select the perfect diamond for every occasion. Stay tuned for more enlightening content and continue your journey with us as we explore the captivating world of diamonds. Please note we just deal with diamonds not with any simulants.
