For the jewellery market we propose our solutions allowing to raise the value of gemstones, in particular - diamonds, and to obtain a competitive advantage on the market for our clients. Diamonds value can be increased by creation of real masterpieces of art using NanoPolishing technology on their surface. Our patent pending solution allows the change of gemstones’ light properties in a way never seen before. We propose change of colour, elimination of undesired yellowish hue of the diamonds, and enhancement of amount of light reflected from gemstones. One of the most interesting aspects of our technology is the possibility of production of stones with “fancy” colours, e.g. blue or pink - more often than not, such stones have a higher value than white stones of similar size.
