* A man-made substitute for diamonds. It is much closer to the physical characteristics of a real diamond than other imitations. * Cubic zirconia (also known simply as 'cz') is the finest available alternative to a diamond. This is because it has many of the properties of a diamond. It has the same shape and colour and, like a diamond, cannot be scratched by dirt or sand. Most people, even trained gemmologists, cannot tell the difference between a well-cut cubic zirconia stone and a diamond using only the naked eye. There are, however, differences between diamonds and cubic zirconia. Although in appearance cubic zirconia looks just like a good quality diamond, it is more dense than a diamond - weighing up to 60% more than a diamond of the same size. In addition, it is of note that cubic zirconia is a man made crystal. If, therefore, a piece of cubic zirconia is not perfect, it is discarded. Only the highest grade and most beautifully polished cubic zirconia stones are used throughout our silver jewellery collection. We believe that cubic zirconia is not merely a diamond substitute but a beautiful semi-precious gem in its own right. Given proper cleaning, cubic zirconia will retain its beauty and brilliance for years. Cubic zirconia jewellery can be cleaned easily using hot soapy water or warm water with a small amount of dishwashing detergent. It might help to first remove any dirt with an old toothbrush.
