Artificial Simulants
Diamond has been imitated by artificial materials for hundreds of years: advances in technology have seen the development of increasingly better simulants with properties ever nearer those of diamond. Although most of these simulants were characteristic of a certain time period, their large production volumes ensured that all continue to be encountered with varying frequency in jewelry of the present. Nearly all were first conceived for intended use in high technology, such as active laser mediums, varistors, and bubble memory. Due to their limited present supply, collectors may pay a premium for the older types.

Famous quotes containing the word artificial:
“These are not the artificial forests of an English king,—a royal preserve merely. Here prevail no forest laws but those of nature. The aborigines have never been dispossessed, nor nature disforested.”
—Henry David Thoreau (1817–1862)
