• Lot Description
  A vivid yellow-green botryoidal mimetite specimen displaying tightly clustered, grape-like globules across the matrix surface. The rounded, bubbly formations exhibit a waxy to satin luster and a rich, uniform coloration typical of mimetite from classic lead-rich localities such as Mexico or China. Fine microcrystalline textures are visible on the surface of each sphere, giving the specimen an appealing, organic aesthetic, 1"H x 1-3/4"W.<br> A softly colored lavender botryoidal chalcedony, often marketed as “grape agate,” featuring well-developed spherical aggregates in shades ranging from pale lilac to deeper lavender-gray. The surface shows an appealing mix of fine-textured microbotryoidal coverage and larger, more pronounced globules, giving the piece strong dimensionality, 3/4"H x 3"W x 2-1/2".
