The metal price is the same everywhere: what sets a jeweller apart is the quality of advice, the range of services and the seriousness of the warranty. Here are the markers that make the difference.
A trustworthy jeweller shows the hallmarks, provides an itemised invoice (metal, fineness, stones), runs a workshop for after-sales and bespoke work, honours the statutory warranty and advises without pushing the sale. For a major purchase (engagement ring, wedding bands), compare at least two shops.

18-carat gold (750‰) bears the French eagle-head hallmark. The jeweller should be able to show it to you and state it on the invoice. No fineness hallmark, be wary.
Yes, if it has a workshop. Resizing a band, replacing a clasp or setting a stone are common services; ask for a written quote first.
