This Coyamito Agate halve is a sophisticated specimen preserved within its natural full husk. It features sharp, medium-width fortification banding that creates the precise geometric patterns characteristic of this iconic Mexican location. A unique highlight of this piece is the calcite-filled center, which provides a creamy, opaque contrast to the translucent agate layers, distinguishing it from more common quartz-filled examples. The stone exhibits a captivating parallax effect, where the internal banding appears to shift and move with three-dimensional depth as the light changes. With a flawless structure and a professional flat mirror polish, this piece offers immaculate clarity, perfectly showcasing the transition from crisp exterior bands to the rare calcite core.
