Imitation Gemstones, either natural or manmade, are effective substitutes for stones that are too expensive or too difficult to obtain. One of the problems facing re-enactors is how to present an authentic appearance on a limited budget. This is especially true regarding jewelry. Many gemstones that were popular in the Middle Ages are too expensive for the average person to obtain. There are several ways to use substitute or imitation jewelry however.
The use of colored glass to imitate gemstones dates back to ancient times. For small jewels this can be very effective. For larger gemstones glass may be too clear, and lacks the inclusions found in natural stones.
Most inexpensive jewelry on the market uses sythetic rather than natural gemstones. These fall into two categories: Laboratory synthetics are exact duplicates of natural minerals. The only difference is that the stone lacks the inclusions and imperfections found in nature. Synthetic imitations are also grown in the lab, but are of a different chemical composition, than the natural stone. When using synthetics stones one should remember that most medieval jewels were cut as cabochons. A facetted gemstone would look out of place on a Viking warrior.
There are a number of natural gemstones that bear a strong resemblance to the cardinal stones—diamond, emerald, ruby, and sapphire. The following is a list of natural stones (plus a few manmade ones) which may prove to be effective substitutes:
- ultramarine (ancient sapphire)
- hyacinth (late medieval & modern sapphire)
