Five Professional Knowledge of Jewelry
Every new season is the peak time to buy jewelry. The Spring Festival is less than a month away. Those who want to buy wholesale jewelry are ready to take action! In this literature, after reading these 6 jewelry tips, I believe that no one can cheat you!
1.Red sapphire “burn”, “no burn”
The concept of burning without burning is mainly used for red sapphires.
“No burning” refers to the gem mined from the mining area, except cutting grinding and polishing without any artificial heating state; “Youyao”, on the other hand, refers to the physical heating of a gem in a specific environment to improve its color and clarity. Since heating does not change the characteristics of the gem, the gem with “burning” is recognized by the jewelry industry. This behavior belongs to optimization, while the gem with burning belongs to the category of natural gem.
In the case of the same color, clarity level, the price of no burning sapphire is higher than that of burning sapphire. For high grade red sapphires, the price difference is even wider.
2.Emerald “immersion”, “oil free”
Emerald in gem clarity as part of the Ⅲ gem, it is hard to find a gem of high clarity, its contents and more complex, so look more have crack, and “immersion” can help the emerald cover these flaws, precious stones look even more bright, it is also a recognised way of optimization, are natural gems in the appraisal. And “oil free” is not immersed in oil optimized natural gems.
Dipping oil must be colorless oil, dipping colored oil belongs to the treatment. In the actual operation of the laboratory, for the behavior of excessive immersion in colorless oil, the description “clarity optimization” will be added in the remarks of the certification.
3.Carat premium
In the jewelry market, the price of gemstones (especially in the transaction of precious gemstones) should follow the “carat premium” rule, that is, the price of gemstones increases with the increase of carat, and not equal multiple, but three times four times, or even dozens of times.
4.The main and deputy evidence of pigeon red gem
Pigeon red is the best ruby, rare production and expensive. NGTCGIA and GRS are most of the professional organizations that issue pigeon haemoglobin gemstones. Among them, the pigeon haemoglobin certificates of GRS are divided into main certificate and secondary certificate. The main certificate of pigeon haemoglobin means that the gemstones have strong fluorescence, while the secondary certificate of pigeon haemoglobin has weak or no fluorescence.
- Be careful with flawless gems
In general, the clearer the gem, the less impurities, the more valuable it will be. But many counterfeits are flawless and beautiful, like synthetic rubies.
Natural flawless gemstones are rare, especially large carat precious stones, even if there are, also basically can not buy, so see flawless gemstones must be careful!
