Natural gemstones have always had a chromatic aberration of ten times, and there are many very professional problems such as clarity, cutting and size. And whether the ruby burns or not, these are all factors that cannot be determined by the naked eye.
For example, the pigeon blood red ruby made in Myanmar, 2ct specifications, costs 50 ~ 65438+ 10,000 yuan /ct without burning, and costs several thousand to more than 20,000 yuan /ct. Royal sapphire, regardless of origin, 4ct specification, does not burn 40,000-50,000 yuan /ct, but burns 1 1,000 yuan /ct.
The price is determined by the relationship between market supply and demand. The rarer natural gems are, the higher the price is. Pure natural high-quality rubies and sapphires can't meet people's needs, so people heat treat some raw materials with insufficient quality to improve their aesthetic feeling. At present, more than 90% rubies and sapphires on the market are heat-treated (that is, fired). In contrast, it is obvious that unburned rubies and sapphires are rarer and more valuable.
Suggest a solution
First, seek a more credible organization to prove it-a third-party jewelry testing laboratory.
Second, confirm that unburned rubies can be returned and burned rubies can be exchanged. Actually, burning rubies is the same. More than 90% rubies and sapphires on the market are heat-treated (that is, fired), and the high price is only based on scarcity.
