In the eyes of the layman, any piece of jewelry that is bright and sparkling looks like something very valuable.
But in fact, the jewelry market is mixed, and there are a lot of seemingly glamorous jewelry that are actually of low value.
part.01-Sakim, Vietnam
Vietnam sand gold, the appearance is similar to **, but in fact, the gold content is about 0, the main ingredient is copper, **low, ridiculed as "** flat". It's just enjoyable to buy it, and the value is not high, let alone benchmarking with **.
part.02-Taiwan sapphire
Taiwanese sapphire is a blue chalcedony, and the so-called Taiwanese sapphire is just his trade name.
The sapphire we know as a corundum group of minerals, while Taiwanese sapphire is just a type of chalcedony with silica as the main component. It can be said that it has nothing to do with sapphire half a dime, and the only feature is that this natural blue chalcedony is indeed one of Taiwan's specialties.
part.03-Freshwater gold pearls
Searching for "golden pearl" on the Internet, there will be two results, one is the South Sea gold pearl, and the other is the freshwater gold pearl. Although the appearance of both is golden, natural gold beads are generally only found in saltwater pearls, and freshwater gold beads are artificially dyed, which are inferior to natural gold beads in terms of quality and value, so don't use the money of natural gold beads to buy freshwater gold beads.
part.04-Tibetan silver, Miao silver
Tibetan silver and Miao silver jewelry tends to be simple and atmospheric, very suitable for local tourism and people who take the national style, although the name has the word silver, the actual main ingredient is white copper, the silver content is low but buy more expensive than pure silver. If you like, you can rent a photo and take a photo.
part.05-Russian rubies
The production of ruby in Russia is almost negligible, so the so-called Russian ruby is actually a synthetic corundum, which is very cheap, not to be confused with ruby.
part.06-Ice Emerald
It has nothing to do with jadeite. A few years ago, it was very hot ice jade, presumably many people know what it is, yes, it is green glass, don't think that it is glass jadeite, and the jadeite that can achieve such quality can only be seen at auction.
