It is important to be informed of choices available to you. Unless we learn, we are unaware that majority of the gemstones in the market are treated in some manner. Otherwise you would be wearing something you can buy from the corner shop but beautiful - not that there is anything wrong with it but it is not the purpose of having a valuable piece of jewellery. It is not just the beauty that makes us want to own something valuable. We all want something that is uncommon and scarce. Why choose an untreated unheated sapphire? ![]() Unheated sapphires mean the sapphire is natural and it has not been enhanced by any form of heat treatment or any other treatment. Unheated sapphires and untreated sapphires are one and the same as no treatment can be applied to a sapphire without the help of heat treatment. Most of the time untreated sapphires are referred to as unheated sapphires as the heat treatment need to be applied in order to perform any other enhancement. This means these sapphires are in their purest form they were mined and simply cut and polished to show their inner beauty. Untreated sapphires means those that have not had any form of treatment to enhance their colour or clarity. Beauty, rarity and durability are the three factors that make a gemstone valuable and why we fall in love with them.
