Which FTC guideline concerning diamonds also applies to colored gems?

• A. Misrepresentation of weight
• B. Fair pricing
• C. Advertising allowances
• D. Ethical sourcing

Answer: (A)

The principle being tested is that weight claims for gemstones must be truthful. The unit used is carats, a standard measure for gemstone weight that directly affects value. Because carat weight is a fundamental property that shoppers rely on across both diamonds and colored gems, the FTC requires that any statement about weight be accurate and not misleading. If a gem is advertised as one carat, it must actually weigh that much; if a piece has multiple stones, the total carat weight must reflect the true combined weight. This shared requirement keeps weight-related information consistent and trustworthy for all gemstones, not just diamonds. The other options relate to different marketing or sourcing aspects that don’t carry the same universal weight-based standard across diamonds and colored gems.
