Poor quality product.
I bought my daughter a t-bar necklace 18 months ago and the clasp broke. It cost £17 for them to repair but it made the necklace look odd as it had faded to nearly silver. They offered to dip it for £30+. In future if I’m spending this amount on dress jewellery I will use a quality retailer like Monica Vinader. Tilly Sveaas products are not of good enough quality to last
