贡献者回答The most likely answer is that the stone is not actually a diamond. It is possible that it is a synthetic diamond or a diamond simulant, such as cubic zirconia or moissanite. These stones can look very similar to diamonds but are not as valuable. It is also possible that the stone is a low-quality diamond, which would explain its lack of brilliance and sparkle.
