In fact, the authenticity of diamonds is easier to identify than other jewels, because diamonds have special drilling instruments. However, like red, yellow, sapphire, emerald and tourmaline, ordinary consumers can't see or test their authenticity immediately. When I was traveling to Taiwan Province Province before, I bought a diamond ring in Lin Hong Group. The service staff took out professional drilling instruments on the spot and tested the diamond for me face to face. Moreover, when I first came to their store to explain, the explanation staff would remind the guests repeatedly that they could buy with peace of mind when traveling. After selecting the goods, they must ask the service staff to help you measure the drill on the spot. Therefore, it is a reputable store and can be purchased with confidence.
