The Specific Gravity Travel Kit contains everything you need to quickly and easily measure the weight of a gem in air, and the weight suspended in water and then calculate its specific gravity.
- Our popular .01 carat scale (uses 2 AAA batteries)
- Weighing apparatus
Tweezers & calibration weight
- Directions for calculating specific gravity
- Chart of the specific gravity of most common stones
Everything fits neatly into a 2 x 4 x 6 inch box. It is compact and convenient to take with you anywhere. For use with stones as small as .33 carats, or as large about 50 carats (depending on dimensions.)
Just add water!
