McReynolds Sotheby's Los Angeles, CA., October 31, 1984, lot 99 Joan and Ted Dorf Collection, no. 193 Agate is a banded, multi-colored variety of chalcedony. It occurs in a boundless amount of colors and patterns and, as such, no two agate bottles will ever be identical. As a stone, the extraordinary beauty and uniqueness of agate was responsible for its great popularity with collectors from the eighteenth century onwards. In the rock it forms in rounded nodules, which must be sliced open to reveal the hidden internal patterns.
