Care and Cleaning
Ruby is a highly durable gemstone with a high hardness rating which means it resist scratches very well and is ideal for everyday wear. It is also a very tough gem but that does not mean it is indestructible. Even a gem as hard and though as ruby may chip or fracture under sharp strong impacts so care should always be taken whilst wearing, putting on or removing your jewellery.
 
You should always store your ruby jewellery away from other coloured gemstones as ruby and sapphire may scratch gems with a lower hardness rating. (All gemstones apart from diamond and synthetic moissanite have a lower hardness rating than sapphire and ruby which both belong to the corundum mineral species)
To prolog the life of the stones we always recommend putting your jewellery on  after any hair products, makeup, lotions or perfumes are applied. 
 
Experts estimate that around 95% of all ruby on the market today has been heat treated to improve its apparent colour and sometimes its clarity. Heat treatment in corundum is stable (permanent) under normal and can often be undetectable so always assume a ruby has been heat treated unless proven otherwise. 
Many rubies have natural fractures or surface reaching cavities or these may be created during heat treatment. To improve the stones clarity and durability it is common for surface reaching cavities in ruby to be filled with a transparent epoxy resin, lead-based glass or sometimes oil. These treatments can be easily detected by a trained gemologist but nevertheless they should always be disclosed by a retailer (treatments are disclosed below if applicable). If a ruby has been cavity or fractured filled it is not safe to put in an ultrasonic or steam cleaner as these cleaners may damage or remove the filling. They should also not be exposed to high temperatures or harsh chemicals during wear.
