- Very effective tool in the use of separating red, blue and green stone from others that might look similar in comparison.
- Extremely useful in detecting certain dyes treated on gemstones.
How to use…
1. Hold your jadeite filter up over the gemstone(s) recommended not holding it directly up to your eye, but keeping it about six to eight inches away.
2. Position the Super Spot Light Torch at the gemstone (Item T33834). The spot light source should not be aimed through the gemstone into the jadeite filter this will not work. You must aim the spot light into the gemstone come back out of the gemstone into the jadeite filter for it to work properly.
3. Place the gemstone(s) underneath the filter and in the path of the strong spot light source. Ideally lay the stones down on something that is bright white to help with light return
4. There are many different colour properties that can be exhibited by gemstones through the jadeite filter. Some gems even have different colours based on the locality where they were found. Above I used the simplest test as an example. The rough gem above is green tourmaline. The jadeite filter displays the stones are red, not green, which means that the green tourmalines contain chromium. With that information in hand, they can be called chrome tourmaline and their value goes up.
5.We recommend purchasing the book Gem Identification Made Easy (item C9508) to help you learn the many different ways the gemstone colour properties through a jadeite filter can help you determine what kind of stone you have. Remember that the colour identification is diagnostic, but not conclusive.
