The hardness of a gemstone is measured on a scale of its Mohs hardness with 10 (the diamond) being the the highest. Care should be taking when wearing gemstone jewellery. Avoid knocks and scrapes to prevent damage and keeping it looking its very best. Below is a list of some of the most common gemstones used in the LULUROX collections.

Much softer than most gemstones, extra care should be taken when wearing pearl jewellery. That said, as an organic material they react well with our body’s natural oils helping to retain their beautiful lustre. Pearls may be wiped clean with a soft cloth and mild soapy water. Do not expose your pearls to excessive heat as this may cause them to crack. When not worn, store in a silk or cotton pouch, never store pearls in a plastic bag.
