A monochromatic engraving captures the layered, striiated patterns of an agate cross-section, with delicate linear marks creating depth and geological rhythm across the composition. The vertical orientation emphasizes the stone's natural banding, rendered in grayscale with intricate detail that suggests both scientific observation and meditative contemplation of mineral formation. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
