Dear, according to our years of experience, most diamonds are inlaid with K gold, which is solid and reliable and easy to shape. Platinum is too soft and easily deformed. Yantai Golden Lady Diamond is a professional loose diamond custom inlay in Yantai, and has been a local merchant for ten years. Of course, Xinhui and Fulai are also local jewelers in Yantai, which are relatively comprehensive. Only Ms. Jin is a professional diamond producer in Yantai. You can look at them all and compare them.
