What is its speci specific gravity
mineral is 10 times heavier than water,

Osmium has the highest Specific Gravity among minerals approved by the IMA, ice has the lowest.

Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water. Minerals with a specific gravity under 2 are considered light, between 2 and 4.5 average, and greater than 4.5 heavy.

Because water at 4 degrees Celsius is the standard scientists use to determine specific gravity, it follows that its specific gravity is 1. However, a water sample at a different temperature or pressure or one containing impurities has a density that differs slightly.
