When mined from the earth or the ancient riverbeds, rough diamonds look like pieces of ordinary molten glass. The raw material holds remarkable, natural optical qualities. But it takes highly specialized skill, scientific knowledge, and tools to turn rough diamonds into the sought-after, scintillating gemstones.
