Like diamonds, the price of rubies has a "carat premium", because the bigger rubies are rarer, so the price will increase exponentially. Generally speaking, the price of rubies below one carat is usually between several hundred and several thousand yuan, depending on the quality. Ruby weighing more than one carat is generally more than 10,000 yuan.

Because most natural rubies are not perfect, there are often some artificially optimized rubies on the market, such as burning rubies. Generally speaking, burning rubies is cheaper. For example, the price of a carat of high-quality burnt ruby on the market is almost 7000 yuan a carat. The unit price of unburned natural rubies of the same quality is more than 10,000 carats, or even higher.
