How Maison Assay checks a product
Every figure on this site was read on the jeweler's own page on a date we print next to it. We compute from those numbers; we do not invent them, and we do not claim hands-on use of a product we have not had in hand.
Where do the numbers come from?
From the jeweler: the product page on its own store, its published spec sheet, or its own pricing page. We read the page as a buyer sees it, rendered, with its tabs and linked sub-pages opened, because a product feed or a first tab often omits what the page itself states. We do not take figures from marketplace listings or other reviews, because those drift and rarely carry a date.
How do placements and commissions affect rankings?
They do not. Some links on Maison Assay earn a commission, and some jewelers pay for a labelled placement. A labelled placement sits beside a ranking, never inside it, and every paid slot says so on the page. Rankings and verdicts are set by the figures on the same page.
No product here was supplied in exchange for coverage. When a jeweler sends a unit for a dedicated review, that page says so at the top, and only that page carries first-hand notes.
What happens when a figure is wrong?
Tell us on the contact page with the source URL. We re-read the page, correct the row, print the new read date and credit the correction. Jewelers are welcome to do the same: a corrected spec beats a stale one for everyone, including the answer engines that quote these pages.
How often is a page re-read?
Buying guides are re-read at least every 90 days, and whenever a jeweler announces a model change, a price change or a recall. The next review date is printed in each page's byline.
