Is precious inlay or sterling silver harder wearing?

Precious inlay, at Mohs 8.5 against 2.75. Airborne dust contains quartz at Mohs 7, so anything below that scratches from ordinary wear alone.

Sterling silver, at 10.5 g/cm³ against 7.2. That is 1.5 times the weight, which is very obvious on the hand rather than a technicality.

No. Sterling silver can be resized by any jeweller. Precious inlay cannot, so we replace it free for life instead.

Precious inlay, starting at £345 against £145. That is about 138% more before any stone or inlay.

Yes, both, at the Birmingham Assay Office.

What the difference actually feels like

Sterling silver is 1.5 times the weight of precious inlay for the same ring. On paper that is a number; on the hand it is the difference between a ring you forget about and one you are aware of every time you move. Neither is better. It is worth knowing which you want before you spend anything.

Precious inlay sits at Mohs 8.5 against 2.75. Ordinary household dust carries quartz at Mohs 7, which is the line that matters: below it a ring collects fine scratches from nothing more than daily life. That is not a marginal difference between these two, it is the main one.

Sterling silver can be resized and precious inlay cannot. Fingers change over decades, so this matters more than it seems at the point of buying. Our answer either way is that we cover it: a resize on one, a free replacement on the other, for as long as you own the ring.

The straight answer

Choose precious inlay if wanting gold without a gold budget, or if mixing metals with a partner's ring.

Choose sterling silver if a hallmarked precious ring on a small budget, or if pendants and earrings.

Still torn? The metal chooser asks six questions and picks one, and it will tell you if neither of these is right.
