The ideal color of ruby ​​is a bright "pigeon red" color caused by chrome ions. You must pay attention to the color when choosing ruby. Sometimes, the red color is not so deep that it is close to pink. At this point, it must be noted that perhaps the gem is no longer called Ruby, and the pink sapphire (Pink Sapphire), which is very different in price.
In addition, because today's technology has been able to color the colorless or light-colored sapphire into a red treasure through the "heat diffusion treatment", which is also known as the "second-degree burning red treasure" on the market. Therefore, consumers must be careful to buy diffused rubies at the price of natural rubies.
At present, the more common ruby ​​consumption trap on the market is a kind of “glass filling†ruby ​​treatment technology, which is similar to the jade glue dyeing technology. Its purpose is to repair the cracks, defects and even color of the red treasure. According to the author's observation, consumers are often not informed of such a treatment, resulting in many consumer disputes in the process of buying and selling.
All in all, the selection of rubies, in addition to avoiding the purchase of man-made products, similar gemstone replicas, also need to pay attention to whether it is optimized. The general heat treatment is a widely accepted treatment. As for the diffusion treatment and the glass filling treatment, the operator should thoroughly inform the consumer of the obligation to avoid the jewelry consumption dispute.
