Colour Filters (Acrylic Squares)

A set of 6x acrylic colour filters in Red, Yellow, Green, Light Blue, Dark Blue and a frosted “White” (diffuser). Insert a colour filter between the light source and the stone to enhance both visibility of features in stones and the observation of spectra. As an example, curved colour banding difficult to see in yellow Verneuil synthetic sapphire becomes more apparent when using the blue colour filter over the light source (the complementary colour to yellow). Coloured filters enhance features in coloured stones, whilst the frosted white filter may enhance features in colourless stones. In spectra, the colour filters can enhance lines that may otherwise be missed – examples can be found on pages 36 & 37 of A Student’s Guide to Spectroscopy by Colin Winter, 2nd edition, OPL Press.

Gemetrix Jewellery Inspector

The Jewellery Inspector allows observation of fluorescence and phosphorescence from SW (short wave) and LW (long-wave) ultraviolet illumination. These observations can help a gemmologist determine whether a diamond or gem is synthetic, treated, or natural. The colour and intensity of the fluorescence provides a useful indicator. A common test is to determine whether the SW intensity is brighter than the LW, which is suggestive of a synthetic diamond.

With the large viewing area (of 50mm x 50mm) the Jewellery Inspector can also be used with a custom jewellery holder (supplied).
