This specific gravity kit helps you identify gemstones and minerals bydetermining their specific gravity. It utilizes user-friendly above-the-scale apparatus so the awkwardness typical of below-the-scale measurement is eliminated.
This kit contains: (Scale Not Included)
The Carat Scale Version of the specific gravity kit requires a scale with tare capability and with a minimum capacity of 50 carats. It's platform must be large enough to accommodate the 1-¾" diameter base of the support. The tared weight of the portion of the kit that sits on the platform is approximately 40 carats and that weight must be subtracted from the overall capacity of the scale to determine the maximum capacity available for specific gravity testing.
