Engagement Ring, Diamond & Jewelry Price Watch

Track jewelry and diamond pricing for US buyers. Report only confirmed, source-backed items from the last 7 days: lab-grown and natural diamond price index moves of 5 percent or more by carat and grade from Rapaport, IDEX and lab-grown trackers; gold, platinum and silver price moves of 5 percent or more with the effect on a typical band or setting; sale windows of 20 percent or more and price changes at Blue Nile, James Allen, Brilliant Earth, Ritani, With Clarity, Clean Origin, Signet brands, Tiffany, Cartier, Mejuri, Catbird and Costco; GIA, IGI and GCAL grading rule changes and certificate fraud alerts; FTC Jewelry Guide and lab-grown disclosure changes and enforcement; insurance and appraisal rule changes at Jewelers Mutual and the major carriers; trade-in and upgrade program changes; tariff changes affecting imported jewelry and stones; and CPSC and state lead and cadmium findings in fashion jewelry. Prefer index publishers, retailer pages, grading labs, the FTC, CPSC and established jewelry trade reporting; ignore retailer marketing without stated prices. Put the category, retailer or index first in the title with the price of a one-carat example where it applies. Use high severity for an index move of 10 percent, a fraud alert, or a sale of 30 percent at a top-5 retailer. Return no more than 6 findings. Push each as a finding with a title, a two-sentence summary, sections for what changed, the price effect, what to do, and the source link. If nothing qualifies, push nothing and submit the run receipt.
