Video: how to determine 333 grade at home and at the jeweler
I noticed the 333 mark on the ring, inherited from my grandfather. I had never encountered such an alloy, so I began to find out on the Internet what these numbers meant. It turned out that the metal itself is of no special value, the ring is interesting only from the historical side. I kept it for a good memory.
The first time I saw 333-gold was when I visited a jewelry boutique in Hamburg. I was fascinated by a thin bracelet made of this alloy, which was incredibly skillful. In appearance, it was no different from the more expensive alloys. I, as a regular customer, would never have thought that the gold content of such beauty is low. I bought this bracelet for my daughter.
I wanted to sell the old bracelet to buyers, but the price per gram for 333-gold is the lowest in Russia. When they told me the final price, I decided to keep the jewelry. Maybe in a dozen years it will become more valuable as an antique.
Choosing items of low-grade gold should follow the same recommendations as for the more expensive alloys.
