Spice Topaz uses a revolutionary patented technique to add spectacular colours to genuine Topaz. With 12 colours to choose from and with a continual research program to develop more, Spice Topaz offers a range of coloured gemstones unlike any seen before. Choose from Summer Blue, Aqua, Liberty Blue, True Blue, Neon Paraiba, Padparadscha Sunset, Pristine, Deep Sage, Fern Green, Diva Green, Peru and Dusky Black.
Using exactly the same colouring agents that Mother Nature uses to add colour to allochromatic Composition gems, Spice Topaz uses its revolutionary and entirely safe process to penetrate colour deep inside the gem. Since the importing of Topaz with radiation treatment was banned in the USA, some American jewellers now only offer Spice Topaz (alongside very rare untreated pieces) and the owner of one store recently told me that the only difficulty consumers now face is which of the 12 brilliant colours to choose.
The technical stuff: why did two scientists spend years developing and patenting Spice Topaz? Well to understand this you need to understand the limitations of other techniques used to add colour to Topaz. Mystic coating can be damaged if not properly looked after. Radiation treatment of Topaz has had a rocky road in the USA over its potential health hazards. Regular diffusion does not penetrate deep into the gem and can therefore be negatively affected by small chips and scratches, plus it is not very effective when used with Topaz. However Spice Topaz diffuses colour deep into the gemstone and is 100% stable and totally permanent.
