Opal stone

Opal is one of the most beautiful and precious gemstones in the world, with 95% of the world's opals produced in Australia. Opal's English is Opal, which originated from the Latin Opalus, meaning "the beauty of the gem." Ancient Roman natural scientist Pliny once said: "On an opal stone, you can see the ruby ​​flame, the amethyst-like stains, the emerald green sea, the colorful, seamless, beautiful."

Among the Opal species, Deborah Opal and Trimble Opal are relatively cheap and have been made into many accessories. But a lot of instructions about opal will make your concept a bit confusing. Most of what they say about opal is mostly for the original opal, not Deborah Opal and Trimble. Only Deborah Opal and Trimble Opal need to avoid water penetration and the original Opal does not. Deborah Opal and Trimble Opal can be cleaned with a soft cloth and a neutral wash, but do not immerse in water. In addition, any opal should avoid bleaching, chemicals and ultrasonic cleaning.

Topaz

Topaz is a mineral belonging to silicate. In the eyes of Westerners, topaz can be worn as a talisman, which can ward off evil and make people overcome sorrow and enhance confidence. Powdered wine with topaz can treat asthma, insomnia, burns and bleeding. China has a long history of understanding and using Topaz.

The highest value topaz is red and Sydney, followed by brown. The yellow topaz is similar in appearance to the cheap yellow crystal, so the price is not high. Colorless topaz has the lowest value. In addition, the current topaz on the market is divided into natural topaz and optimized color-changing topaz. It is rare in the large-scale topaz market without natural color change, and the optimized color-changing topaz is optimized in the process. No other substances were added, so it was still recognized as a natural gem in the identification of jewelry.

Morgan Stone

From a mineralogy point of view, the Morgan Stone is a pink beryl (PinkBeryl), an intimate of emeralds and aquamarine. The color of the Morgan stone is orange red and purple, which is unusually beautiful. Its name is derived from a famous gem hobby collector in the United States and the name of a banker, J.P. Morgan. The Morgan stone is so bright pink because it contains manganese.

From different angles, it can be found that the Morgan stone presents two delicate subtle colors: light pink and dark pink with blue. Due to the scarcity of production and the beauty of the color, this unique magenta gemstone is of high value and the price of the premium is above the ordinary quality emerald. The morganite can also change color by heat treatment, green blue turns blue, light blue turns into deep sky blue, yellow green turns blue, orange yellow turns pink and so on.

Schafflerite was discovered in 1967, when it was tested that it was neither emerald nor jade, so the world boldly identified this new gem. In fact, "Shafley" is not a beautiful stage name that Tiffany specially created for the packaging of stars. It is precisely the name of its birthplace: Shaffer National Park. This word from local language has quite a sensible meaning.

Schafflerite

Shaflai Stone is a semi-precious stone, and now it is one of Tiffany's main push jewels. The scarcity of production is the reason why it has become the new favorite of gems. In addition, its "three highs" is also very important. The first is high brightness, which stems from its inherently high refractive index, which is a strong fire from time to time; the famous high purity makes it the emerald emerald of the emerald family far behind, with very little impurities. A reiki; high-saturated rich color is another weapon of saffron.
