Often natural rough stones are being heated to enhance their colour and burn out the impurities. Heating without any chemical component is approved by the International coloured Gemstone association. Some stones like rubies are heated with silica powder so enabling cracks being filled with silica (glass). Moreover rubies& sapphires are heated with beryllium that enhances colour and lustre and is detectable in lab testing. It is not commonly approved or accepted, so any such treatments ethically should be disclosed to the buyer. Other very commonly practised treatment is lead glass filling in cracks at a very high temperature, this is done in corundum group stones, it makes the stone fragile. Such commercially, named ‘glass filled stones’ are very economically available in the gem stone markets.

Another version of treatment is diffusion, in which outer layer of the stone is diffused with chemical colours, since it is in a thin outer layer, a simple re polishing process removes the colouring effect. We do not recommend to wear such treated or diffused stones for astrological purpose. The bio energy of such stones is completely disturbed and changed, so such stones cannot make their expected impacts on the wearer.

Gem testing labs check chemical components and natural origin of a stone, they do not look into bio energy of the stone neither investigate its quality. Many ones do not even specify whether the tested stone is being artificially treated by crack fillings, until demanded. To avoid any treated or artificially quality enhanced stone, ask for quality certificate (Q cert from ANU) let us take care of your interests fairly and trustfully.
