The most reliable way to determine if a diamond ring is real is by seeking an appraisal from a certified jewelry appraiser. A jewelry appraiser determines the value of jewelry.
A jewelry appraiser is trained in differentiating between diamonds and man-made stones, such as cubic zirconia. A diamond is valued according to its cut, color, clarity and carat weight. The presence and number of imperfections determines a diamond's clarity, and its color is graded from colorless to darkening hues of yellow with colorless being most expensive. A diamond's cut affects its brilliance and sparkle and is graded on a scale from excellent to poor. For gold rings, the appraiser determines the weight and fineness of the gold together with the workmanship on the band. After examining these elements, an appraiser determines the value of a ring.
