The Consistency of quality is often where lackluster standards become noticeable. A single piece of jewelry may appear to be of good quality, but if you look at several pieces, definite inconsistencies become apparent. Ring sizes may be inaccurate by more than a whole size, but careful attention to quality control should limit inaccuracies to less than a half size. Beware of size grouping, like 6-7 , 7-8. If your size requirements are 6, 7 and 8, you may receive all 7's from merchandise shipped in grouped sizes. The perceived savings are actually spent re-measuring and re-labeling your stock. Everyone should agree, time is better spent selling the merchandise.
