自然の中で, mineral crystals that can be used as gems are very rare. したがって, they are expensive, so that many people cannot afford to pay attention to them, so they are expensive, so that many people cannot afford to pay attention to them, and the output is too small to meet the increasing demand.
したがって, people use artificial methods to make gems. The earliest artificial gemstone is glass, which has existed thousands of years ago. By the 20th century, a variety of gems with the same properties as natural products were produced, ルビーなどの, サファイア, and emeralds.
例えば, Swarovski’s products are mostly man-made gemstones, whether they are titled “結晶” または “rhinestone”, they are actually glass. They win by shape and are not natural gems in nature. The nature and structure of artificial rubies and sapphires are exactly the same as natural ones. Artificial amber, except for the added “時間”, has the same texture as natural. From a purely beautiful point of view, the visual effects of artificial gemstones are by no means inferior to natural ones.
The quality of artificial gemstones can be controlled, and their color and transparency are very good. 同時に, artificial gems can be produced in large quantities at low prices and are easily accepted by customers. したがって, artificial gemstones occupy a very important position in the jewelry market.
今日, almost any kind of natural gemstone can be manufactured artificially. As for whether it will be sold in the market, that is not necessarily true, because only the price is much lower than the natural gemstone of the same appearance will be bought. Some artificial gems are now more expensive to produce than natural gems, so it is impossible to sell them on the market. 例えば, artificial diamonds can be made, but the cost is equal to or higher than natural ones, which is very uneconomical.
