925 sterling silver rings wholesale Basic conditions of natural gemstones

The agate, once known as the Seven Treasures of Buddhism in history, has fine texture and unique patterns. It was also loved by people in ancient times. Now it has become a low-grade gem due to the increase in production areas. Navíc, synthetic gems are the same as natural gems in many properties such as refractive index and density, but because they can be produced at will, most of them are far away from natural gems in price.

Navíc, the value of gems is sometimes affected by superstition color. Ve starověku, Opal used to be the most beautiful and unparalleled gem in the eyes of people. It has a ruby-like flame and an emerald-like green sea. After the American poet Scott’s novelBeauty on the Lakecame out in 1825, the price plummeted. This is because the book recorded that the flash of opal burned a beauty. Since then opal has been regarded as an ominous thing. Now the price of opal has rebounded, but it is only between the upper part of mid-range gems and the bottom of high-end gems.

For a gem, krása, trvanlivost, and scarcity are a comprehensive index that people have summarized for a long time. Only minerals, mineral aggregates, rocks, atd. produced in nature that can meet such standards are called gems.
