You should be talking about black Tahiti pearls in peacock green, which is not called dark green pearls professionally. If it is a high-quality genuine natural Tahiti black pearl necklace, it will cost at least 30,000 to 40,000 yuan. I bought one for my wife, more than 60 thousand, which is the one in the picture. In addition, I want to remind you that if all pearls are the same color and shape, you should be careful about authenticity. I bought it in official website, a pearl beauty. I feel more at ease with the certificate.
