Web2. sep 2024 · Specific gravity is a measure of density relative to the density of a reference substance. The reference material could be anything, but the most common reference is pure water. If a material has a specific gravity less than 1, it will float on water. WebGemstones form a varied group of mostly minerals used to make jewelry. The major differences between gemstones and glass include hardness, refractive index and density. Glass has lower hardness, lower refractive index and lower density than true gemstones. One exception, opal, has unique color play.
