IGI is relatively weak, except for SSEF, Gubyrin Laboratory and GRS, which are relatively good appraisal institutions in the world at present.

Judging from the difficulty of the exam, GIC Question 9: Does Aquamarine have an international certificate? Is there a clear grading standard? Hello! ~ Gemstones can usually be classified by 4C standard, such as aquamarine, the color is definitely sky blue, and sea blue is the best. The clarity is not observed with a magnifying glass that is 10 times that of diamonds, but with the naked eye. The fewer defects and inclusions, the better, and the heavier the weight. Cutting is to make the facets smart and wear-free. I suggest that it is best to observe with a magnifying glass! ~

The main factors that determine the value of aquamarine are size and color. Internationally, aquamarine with dozens of carats or more is not uncommon. Generally, the price of deep-sea sapphire is about 30%-50% higher than that of shallow-water sapphire. In addition, the cutting, the number of revolutions and the fineness of polishing also have a slight impact on the price of gemstones.

Try to avoid bumping when wearing aquamarine, and try to take it off when you get home.

The international certificate has HRD GIA FGA domestic certificate, and only the National Jewelry and Jade Quality Supervision and Testing Center (NGTC) is more authoritative!
