I answer your question
Because their is too much wrong believing in jewelry!
What is Pure Gold?
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft and malleable! Can you believe it ??
Pure gold is also called 24K Gold. In its pure form gold isn't strong enough to do jewelry. That's why jewelry are made in 18K, 14K or even 10K.
What does it mean?
10K = 41% of gold
Does my jewelry are pure gold?
Contrary to popular belief, when you purchase a gold jewelry, the metal used for the jewelry probably is NOT 100% gold why?
Pure gold or 24K gold, is gold that hasn’t been mixed with any other metals. 24K gold isn’t used for jewelry for several reasons:
First, it’s extremely soft. Because pure gold is so soft, it bends and warps easily, making it a poor metal for jewelry that needs to retain its shape. Pure gold also scratches easily, meaning it doesn’t take long for pure gold jewelry to become scuffed or broken.
Second, it’s very bright. The color of pure gold is much brighter and more orange than what most people associate with the gold used in jewelry. Because of this, it generally isn’t an attractive metal for jewelry.
Third, it’s extremely expensive.
My jewelry are in 18K or 75% of gold and 14K so 58% of Gold. I NEVER do jewelry in 10k or 9K because they contain less than 50% of gold and I personally consider that you can't call this material as gold.
However, 24K gold tends to be more popular in China and other Eastern markets, where it’s used in traditional Chinese wedding jewelry such as bangles, in gold bars and as a material for other collectible items.
What is a natural gemstone?

What is a treated gemstone?
Treated gemstones have been enhanced to display the best color or clarity. There is a lot of treatment in the gemstone’s world such as heating, bleaching, glass-filling, irradiation ...
But all treatment does affect the gems in the same way. Some treatment can be “acceptable” because they kind of “respect” the stones or allow them to show a part of them that was unknown. That's the case of the Blue Zircon from Ratanakiri. Naturally Brown, this gem becomes blue when it is heated. But ONLY the one from Cambodia react like this. This treatment gives a value to the gem because it is the only way to discover this UNIQUE blue who doesn’t exist in any other gemstone.
