Gauge Digital Square
The Digital Gauge measures 0-26.40mm (about 1 inch) in 1/100th of millimeter increments and is switched on or off at the hit of a button. It can also switch between imperial and metric measurements and has a zero reset button. The head is a ‘Leverage’ style allowing measurements to be taken in three ways, including measuring inner and outer diameters. It can be used with one hand and takes a 1.55v SR44 battery.

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.
Polariscope PT (Black Desktop Type with 2 Light Sources)
Black desktop type with 2 light sources.
RI Fluid (1.81)

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).
Pencil Torch (Full Spectra)
Can be used as a Spectroscope light source. Requires 2 x AAA batteries

Jade, A Gemologists Guide by Lotus Gemmology
While the literature on jade is vast, perhaps greater than any other gem, there is a distinct lack of a volume in English that treats jade as a gemological material. This book is designed to fill that gap, with extensive information on the history, sources, appraisal and identification of both treated and imitation jades. A must have for collectors, dealers, gemmologists, appraisers, curators and anyone else with an interest in this fascinating gem.
