Pam diamond (or Pam Brilliant). diamond that weighed between 112 and 115 carats (authorities differ) when found, supposedly sometime before 1891, in the Jagersfontein Mine, Republic of South Africa. After the gem was cut into a 56.6-carat brilliant, it is said to have attracted the attention of Queen Victoria. She asked to have it shown to her at Os­borne House. At that time, the Duke of Clarence, her grandson and heir to the throne, was engaged to marry Princess May of Teck (later Queen Mary). The untimely death of the young Duke in 1892 put an abrupt end to the negotiations. The present location of this stone is not known. An alternate name for it is the jagersfontein Brilliant diamond.
(pam-peel"). A dropshape that is related closely to the briolette; it has the circular cross sec­tion of the briolette but is usually more elongated.
