Wow, very good comparison @goldmatters, I really love the way the two different gold hearts have the same shape, but we can clearly see the difference even from their color.
Also, I was wondering, if the two gold hearts have the same shape, how can you know which is pure 24karat gold?
This led me to carryout a research, and I found out two ways to know genuine pure 24 Karat gold.

• 1 Look For The Hallmark

Nearly all real gold is stamped with a hallmark that notes the karat weight of the jewelry, like 10K or 14K or 24k (like in the case of mene) . This stamp is usually found on the clasp of a necklace or bracelet, or on the inner band of a ring. Since the purity of American-made gold jewelry is measured in karats, there will be a stamp on these pieces with a number followed by the letter "K". The number simply indicates, in parts per 24, how much of the metal is actually gold. For example, a mark of "14K" means that it is 14 karat gold and that 14/24 (just over half) of the metal is gold. By the same token, 24K would be 100% pure gold. If you checked the gold bracelets or rings on https://mene.com, you'll find the hallmark stamp of 24k gold, shoeing the genuine nature of mene.

The European system is a little more straightforward. European gold is marked with the gold content expressed as a decimal: ".585" would be 58.5% pure (incidentally, this is the same as 14 karat gold) and ".999" or "1.000" would be pure gold and thus the same as 24 karat. Nonetheless, if an item of jewelry does not have this stamp - it is not necessarily proof positive that the item is made from fake gold. This is particularly true of older items of jewelry,but yet the stamp is a good step to start.

• 2 Heaviness Test and Magnetization Test

Drop your gold item into a jug of water. Gold is a heavy metal. Real gold should sink. Any piece of supposed gold jewelry that floats is likely fools’ gold or fake gold.

The magnet test is also a good test to determine if gold is real or fake. If your gold item is attracted to a magnet, it is definitely not real gold. Still, this doesn’t mean that there is no gold in your item, just that it is not made with a substantial amount of gold.

When you carry out all these steps on mene gold jewelry, you'll find them to pass all these test. If you need a trial, just visit my link https://Mene.com/invite/pFa5pC to find out more on the mene website.

Awesome job @goldmatters, am sure getting a lot of advertisement tips on mene gold from these your posts, I'll surely put them into practice. Thanks
