Nuummite Tumble Stone – Natural Polished Stone

This nuummite tumble stone is polished from natural stone and features a smooth finish with deep black to dark charcoal color and subtle flashes of bronze, gold, or silvery iridescence depending on the angle of light. The polished surface highlights the stone’s dense structure, layered mineral character, and shifting reflective detail, giving each piece a distinct appearance. Nuummite forms as a metamorphic rock composed primarily of anthophyllite and gedrite, created over long geological periods under heat and pressure. The tumble shape gives the stone a rounded polished form that is easy to display, collect, gift, or use as a decorative accent. Every tumble stone will vary in flash, tone, inclusions, and surface detail, making each polished piece unique in natural character.
