Affiliate disclosure

IfTheRingFits is free to use and carries no advertising. It is intended to be funded by affiliate commissions, and this page explains exactly what that means for you.

Last updated 20 October 2026.

Outbound links

Once the tool has told you what size stone you want, it offers links to a few retailers who sell that shape. What is true of them:

• Commission does not change the order. The retailers appear in a fixed order that has nothing to do with what any of them pays, and the fit verdict is arithmetic on millimetres — it cannot be influenced by money, and is not.
• No retailer has paid to appear. Being an affiliate is something this site applied for. It is not something a retailer bought.
• Nothing about you is sent. Not your photo, not your hand's measurements, not your ring size. The link goes to that retailer's diamonds in that shape. Where a retailer's search can be set from a link, the link carries the carat range and length-to-width ratio of the stone you chose, the depth and table percentages a well-cut stone of that shape usually has, and whether you asked for natural or lab-grown — so the search opens on stones like it. That is a description of a diamond, not of you. The millimetres stay on screen for you to check against each listing.
• The click is counted, without identifying you. The link passes through a page on this site so the count of clicks per retailer is recorded, in the same cookieless way page views are. See the privacy notice.

What an affiliate link is

If the site later recommends a diamond or a setting and you follow that link to a retailer and buy something, the retailer may pay this site a commission. The price you pay is exactly the same either way. A commission comes out of the retailer's margin, not out of your pocket, and following a link never obliges you to buy anything.

How links will be marked

Disclosure will appear immediately alongside the recommendations themselves — not hidden in a footer, and not on a page you would have to go looking for. If a set of results can earn this site money, it will say so where you are looking at it.

What decides what gets recommended

This is the part worth reading. The site exists to answer one question that others do not: whether a particular stone physically fits a particular setting. Recommendations are filtered by that geometry first — a stone whose girdle is wider than your setting's seat is excluded, regardless of who sells it or what it pays.

That is a measurement, not an opinion, and it is not for sale. No retailer can pay to be shown, to rank higher, or to bypass the fit calculation.

Where the site can check a listing's stated carat weight against its stated dimensions, it will flag ones that disagree — even when the listing is one it would earn from.

What this site is not

• It does not sell anything and takes no payment of any kind.
• It is not a valuation, an appraisal, or gemmological advice.
• The render is a geometry tool. It shows true size and proportion and a plausible facet pattern; it does not predict how a real stone will sparkle, and it is not a photograph of any actual diamond.
• Measurements depend on how carefully you calibrate. Treat them as a good guide, not as a substitute for a grading report.

Your privacy is unaffected

Affiliate links do not change how your data is handled. Your photo is processed in your browser and never uploaded, and nothing about your hand, your measurements or your ring size is sent anywhere. See the privacy page for the detail.
