UV Long and short wave viewing box

This Light-Box Offers both Long wave and short wave ultra violet light. Ultraviolet light tests are important for separating and identifying-gemstones. It is particularly useful in separating-many synthetics, doublets and triplets from natural-gemstones. This particular unit has a reflection free viewing area with protective glass to block the UV short waves from-damaging your eyes. It also has a indicator inside that allows you to be certain which light (long or short) you are using. A-classic

UV BOX Long-wave, Short-wave

This-unit is a great size it is not as large as the previous models. Super easy to use just keep you stone in your tweezers, hold under the appropriate light and press the buttons. WOW I love this tool so easy!!! The viewing window is 3x making the reaction easier to-see.

Spectroscope large Prism with scale

Reading-a spectrum has to be one of the most-frustating things, you have to get the light just right then you have to keep your hand and stone steady while you try to look out of the "corner" of your eye, while keeping boh eyes open!!! OMG.. Well this spectroscope makes that alittle-easier, it has:

an adjustible slit, this allows you to control the amount of light

sliding focus tube, so you can focus on different areas of the spectrum

Lighted-Scale allows you to be more accurate in the description of your spectrum

The scale has a sliding-focus

Calibration knob, that allows you to move the scale to the correct possition to ensure getting the most accurate-reading.

Spectroscope Defraction grating Medium

Medium-sized portable diffraction grating spectroscope. the diffraction-grating spectroscope produces a full, evenly spaced-spectrum. With sufficient light, you should be able to locate the absorption lines easily throughout the entire visible spectrum. Very portable and surprisingly-easy to read.

Specific Gravity Kit with Carat Scale

A Great Kit! A most have for Gem Identification, as well as metal identification, gold, silver platinum! it can even determine the purity.

There are no TOXIC- chemicals to deal with! only clean pure water. Our KIT comes with:

1. Tim Flanagan's Universal -Specific Gravity Kit (we think it is the BEST)

A specially selected Carat Scale that is accurate to the .005 carat. The accuracy is extremely important to your results! we recommended using no less than .005 carat -accuracy

Simple straight Forward instructions

A calabration tester

A complete chart of over 300 gems and minerals, sorted by their unique Specific gravity.

And our Promise that if you are not -thrilled we will return 100% of your investment.
