Gold necklace for DD - where to get something nice but not too expensive?

[Hecatoncheires]

May I please have your recommendations for where I can get a gold necklace for my DD? Nothing too outrageously expensive (£150 max) but something that won't turn her neck green and won't break the first time she wears it. It's been a long time since I bought any jewellry so I'm out of touch. Thanks for any advice.

DLouise have lovely items and, although not real gold, they do not discolour or make skin go green. I wear mine all the time, showering, washing up etc. I've bought several items for myself and as gifts.
Great ethos and they have a 3 for 2 offer atm so I've chosen 2 new pieces for myself and one for my friend's birthday so a great deal.
I have a necklace (paper clip) with matching bracelet, two rings and anklet (for summer).
I bought my DD (25) pieces too.
I have bought from Monica Vinader but think DLouise is much better value.
DLouise have gorgeous packaging too.

My 16 year old daughter is very keen on Astrid and Miyu

I have some MV stuff that's lasted really well- I've treated it very badly too. Wear it in the pool, sea, etc. But would agree you might be able to get a decent 9ct necklace for the same price. MV did do a massive 50% off last year on black friday though if that helps?

Astrid and miyu- I've had a necklace and 2 pairs of earrings be faulty and their customer service was appalling. I wouldn't purchase from them again. Also was given a pair of their earrings as a bridemaid gift and everyone's looked slightly different- no standards at all.

Have a look at Kiri and Belle - they do solid gold and gold filled! Lovely little small business that makes hand crafted jewellery . If you sign up you far get 10% off your first order but maybe if you can wait till Black Friday I believe there is a bigger discount! You can choose special birthday pouches add gift messages too. https://www.kiriandbelle.com/collections/necklaces

Thanks again for all of your suggestions, much appreciated. I predict a very happy DD on Christmas day. 😀
