"Gem Wizard" Tang Huimin
What is the most important condition for collecting rubies?
The main factors affecting the price of ruby are: color, impurities, carats and cutting. The color is preferably bright red or red; Impurities are of course best invisible to the naked eye; The number of carats should be above 1 carat, which is more collectible. And the cutting machine must have at least 40% firepower. In addition, the origin of rubies is also very important. Most importantly, I think a credible appraisal certificate is essential for ruby, whether it is investment or financial management.
Where in the world are rubies of higher value?
It is recognized that the most beautiful ruby in the world is produced in Magok, Myanmar, and Mozambique in Africa has also produced very beautiful rubies in recent years, which has begun to attract the attention of collectors and buyers all over the world.
Ruby Collection Why is "Pigeon Blood Red" the most collectible?
Simply put, the color of "pigeon blood red" is rich and bright, just like pigeon blood, which is recognized as the most beautiful color of ruby. Usually rubies are bicolor, so they all appear purple or pink. It is not easy to achieve bright "pigeon blood red". Generally, it is only produced in Myanmar, and the output is extremely low. At present, the best color in the world is called VividRed. If you indicate the origin of Myanmar and pigeon blood, it will increase commercial value, while Mozambique generally only indicates bright red.
Will the value of heat-treated rubies be discounted?
It should be said that 90% rubies on the market are heat-treated. In principle, the heat-treated ruby is acceptable in the jewelry industry and appraisal industry all over the world. If consumers want not only heat-treated rubies, but also high-quality colors, they must pay more money. There has been a wave of "no burning control" recently. Some buyers who pursue perfection only want rubies without heat treatment, which makes the store quite a headache. In the early years, it was only necessary to pay 1 to 2 times more, but now it is increased to pay 5 to 10 times more.
Ruby Collection More than a few carats of rubies are worth collecting?
If it is a heat-treated ruby, it should appreciate faster than 3 carats. If it is a ruby without heat treatment, it can be collected above 1 carat. As far as rarity is concerned, it is quite rare if it is not heat-treated for more than 3 carats, and the color of ruby is preferably above red.
What internationally recognized identification certificates do I need to refer to when collecting rubies?
GRS(Gem ResearchSwisslab) certificate is the most popular certificate in the international certificate market, which can be accepted and certified in Thailand and Hong Kong. If you need to identify and indicate the origin of the red envelope stone and other detailed information, Swiss Gubyrin Laboratory is also a world-renowned identification center. GIA certificate provided by the merchant can also be used as a reference.
