Use our free Gemstone Specific Gravity Calculator to accurately determine the density of your gems. Simply input the weight in air and submerged weight in water to get the specific gravity (SG), a fundamental property for gem identification and appraisal. Essential for gemologists and jewelry enthusiasts.
Formula:
Specific Gravity (SG) = Weight in Air / (Weight in Air - Weight in Water)
- Weight in Air: The weight of the gemstone measured in air (in grams).
- Weight in Water: The apparent weight of the gemstone when submerged in water (in grams).
