This vintage 18k yellow gold pendant features a sculptural ram's head set atop a natural agate slab. The oval agate base showcases rich brown and caramel banding, forming a strong contrast against the polished gold mount. At the center, the raised ram's head is crafted in detailed relief, with spiraled horns accented by a row of round brilliant-cut diamonds set in white gold. A single ruby cabochon is set as the eye, adding a subtle touch of color and dimension. The pendant measures approximately 1 5/8 inches in length and 1 1/2 inches in width. Stamped “750” and “B3” on the reverse, though the marks show light wear consistent with age.
