Large jewelry with good color and good appearance has the function of maintaining and increasing value. As Yuqi Zhang said, any diamond smaller than one carat is a broken diamond and worthless. Many such precious jewels are not sold by jewelers. For example, Tai Chen Lan opened a jewelry store with her own investment, and the treasure in the store was the diamond "China Star" that she bought at sky-high price. Show and not sell.

If you must sell it, it may be an economic problem, and you need to sell a batch of jewelry to turn over the capital.
