The "diamonds" used for the scenes during the climax of the movie were actually Herkimer Diamonds borrowed from the Herkimer Diamond Mines of Middleville, New York. They are doubly-terminated (two-ended) quartz crystals that are found in only two places in the world. They were the only gems that would look enough like diamonds and be that large. As a kind of tribute, Tim Curry's character's first name is "Herkermer" (his character does not appear in the Michael Crichton novel upon which the movie was based).
