  3. Rough diamonds have a unique crystal structure that sets them apart from other stones. They often form in an octahedral (think two pyramids stuck together) or cubic shape. Their color can vary from clear to slightly tinted hues, but don’t expect the bright sparkle of polished diamonds just yet.

    • Performing Simple Tests at Home 1 Look down at the top of the crystal and count the sides. Diamonds are cubic, while other similar stones like quartz are hexagonal.
    • Performing a Specific Gravity Test 1 Weigh the crystal on an electric scale and record the weight. You can purchase an electric scale online.
    • 1. Determine whether the diamond was found near kimberlite pipes. Kimberlite pipes are igneous stones, or stones that formed from molten magma, and can found under the surface of the soil.
