FAQ
Clear answers to help you choose your NTHIRTYTHREE jewellery with confidence.
585 gold contains 58.5% pure gold. The remaining metals influence its colour and durability. Our 14K gold jewellery is made from this precious metal alloy. Check the material listed on each product page; our silver jewellery is made from 925 sterling silver.
Our gold and silver jewellery is crafted in Italy. Each piece is delivered with an NTHIRTYTHREE jewellery box and a certificate of authenticity.
Length and width describe the proportions; weight adds another useful point of comparison. Compare the approximate weight for the length you select, together with the material, dimensions and chain style. Small weight variations can occur during production.
Curb chains have closely linked, flattened links. Figaro chains alternate shorter and longer links. Box chains have a geometric profile, while anchor chains feature oval links. Choose the style you like, then compare the available widths and lengths.
Measure a necklace or bracelet that fits you well and compare it with the options on the product page. Necklace length determines where the chain sits; width changes how subtle or prominent it looks. The fit also depends on your proportions. Use our jewellery size guide or email us for personal advice before ordering.
Store each piece separately. Avoid contact with chlorine, cleaning agents and cosmetics, and remove your jewellery before swimming or sport. Clean gently with a soft cloth and lukewarm water, then dry carefully.
