What does dopped mean?
Dopped is the past tense and past participle of the verb 'dop', a term of art with two distinct professional uses. In South African mining vocabulary, a 'dop' is an apparatus for lowering or raising cages, skips, and loads in a vertical mineshaft; to say something was dopped is simply to record that it was so conveyed up or down the shaft. In the gem-cutting and lapidary trades, a dop is a small metal holder into which a stone is cemented or clamped so that it can be ground and polished without being touched by hand, and a stone that has been dopped is ready for faceting. Glassmakers use the same idea when they attach a gather of hot glass to a punty rod. The word belongs firmly to technical jargon rather than everyday speech, and its usefulness lies almost entirely within these trades.
Past tense and past participle of 'dop': to lower or raise (a load or conveyance) in a mineshaft using a dop; or to mount (a gemstone or gather of glass) on a holder for working.
"The workers dopped the equipment down before the shift ended."
Almost exclusively found in mining and lapidary/glassmaking technical contexts.
A device or holder used to lower loads in a mineshaft, or a clamp in which a gemstone is held during cutting and polishing.
"The cutter fixed the stone firmly into the dop."
In gemmology the plural is regular ('dops').
Applies to the noun sense only; the plural follows the regular English pattern.
"The workshop kept a drawer full of brass dops in various sizes."
Before a diamond can be cut, it must be 'dopped' — gripped by a little clamp whose name comes from the same word miners used for lowering cages down a shaft.

Etymology of dopped
The noun 'dop', from which dopped derives, is recorded from the nineteenth century and is associated chiefly with South African English mining terminology, though its ultimate origin is uncertain; some sources link it to Dutch or Afrikaans usage. The lapidary sense of a small holder for gripping a gemstone developed in the diamond-cutting trade and spread internationally with that industry. The related verb followed the noun in both domains.
