Rings are generally 3-6 grams, and the price depends on the technology and purity. Recently, the price of futures gold is generally around one gram of 240 yuan, and the gold ornaments of the same specification generally add a dozen to dozens. If the gold content is very low and other metals are mixed, it will be very cheap, and it seems that ordinary gold shops will not sell very cheaply. As for the necklace, there should be more than ten grams, twenty or thirty grams to one or two hundred grams. A very delicate lady necklace won't be too heavy.
