This specific gravity kit helps you identify gemstones and minerals by determining their specific gravity. It utilizes user-friendly above-the-scale apparatus so the awkwardness typical of below-the-scale measurement is eliminated. This kit comes with: (Scale Not Included)
The Gram Scale Version of the specific gravity kit requires a scale with tare capability and with a minimum capacity of 50 grams. It's platform must be large enough to accommodate the 3-¼" diameter base of the support. The tared weight of the portion of the kit that sits on the platform is approximately 26 grams and that weight must be subtracted from the overall capacity of the scale to determine the maximum capacity available for specific gravity testing.
