Diamond

Moh's hardness of 10

    Thirteen diamonds collected from the Prairie Creek Lamproite in Southwest Arkansas are shown.  Note the variety of colors each stone displays as well as the adamantine luster which is common to all.  White, colorless, yellow, brown, and black are common colors found in the Arkansas deposits.  Total carat weight of the stones is ~1.6 carats.  The fancy canary (yellow) colored stones can be quite striking and beautiful.  An example displaying a deep canary hue is shown at the ten o'clock position.  A colorless stone is shown at the nine o'clock position.  The diamonds were photographed resting on a blue hued rock (lamproite) which is deeply weathered.  The diamonds were freed from the matrix as the lamproite decayed.
