Before you pay, a few questions avoid most surprises. They can be asked in a shop or by message.

## About the metal

1. **What metal is it and what purity?** 18-karat gold, 925 silver… See [basic metallurgy](https://www.711grados.com/en/basic-metallurgy-for-jewelers/).
2. **Is it solid, plated, filled or vermeil?** See [solid gold, plated and vermeil](https://www.711grados.com/en/gold-plated-filled-vermeil-and-solid/).
3. **Does it have a hallmark?** See [hallmarks and punches](https://www.711grados.com/en/jewelry-hallmarks-and-stamps/). Some small or handmade pieces do not; in that case, ask for an invoice stating the metal.
4. **Does it contain nickel?** Important with sensitive skin. See [hypoallergenic jewelry](https://www.711grados.com/en/hypoallergenic-jewelry-and-nickel-allergy/).

## About the stones

5. **Is it natural, lab-grown, synthetic or imitation?** See [natural and lab-grown](https://www.711grados.com/en/lab-grown-vs-natural-diamonds/).
6. **Is it treated?** Many gems are heated or filled; that is normal, but it should be disclosed.
7. **Does it have a certificate?** See [how to read a certificate](https://www.711grados.com/en/how-to-read-a-diamond-certificate/).
8. **Is it suitable for everyday wear?** See [stones for everyday wear](https://www.711grados.com/en/gemstones-for-everyday-wear/).

## About the piece

9. **What size is it and can it be adjusted?** See [ring size](https://www.711grados.com/en/how-to-find-your-ring-size/) and [resizing](https://www.711grados.com/en/ring-resizing/).
10. **How much does it weigh?** Weight lets you compare prices.
11. **How do I care for it?** See [caring for gold](https://www.711grados.com/en/care-and-cleaning-of-gold/), [silver](https://www.711grados.com/en/care-and-cleaning-of-silver-jewelry/) and [stones](https://www.711grados.com/en/how-to-clean-gemstone-jewelry/).

## About the purchase

12. **What warranty and return policy is there?** And who repairs the piece if it breaks.
