Our CESTRIA collection features natural diamonds and precious gemstones, including rubies, sapphires, emeralds and opals, beautifully set in gold and platinum.

Each piece is individually selected, with details of its gemstones, precious metals and key characteristics provided in the product specifications.

Natural gemstones can display subtle variations in colour and internal characteristics known as inclusions, which contribute to their individuality. Known gemstone treatments are disclosed where applicable.

An AGI Diamond Identification Report is an independent assessment providing information about a diamond's characteristics, including its carat weight, colour, clarity and cut, where assessed.

Eligible CESTRIA diamond jewellery is accompanied by AGI documentation, giving you additional reassurance and a clearer understanding of the diamonds in your chosen piece.

The exact documentation supplied with each item is detailed in its product information.

Eligible CESTRIA jewellery is supplied with an independent insurance valuation, providing an estimated replacement value for insurance purposes.

This can be useful when arranging insurance cover and provides an additional record of your jewellery's assessed characteristics and value.

An insurance valuation is separate from the purchase price and does not represent a guaranteed resale value. Where included, this will be confirmed in the individual product details.

Yes, professional resizing is available for suitable CESTRIA rings, depending on the design, setting and gemstones involved.

We understand how important the perfect fit can be, particularly when choosing a ring for someone special. Our team can help you determine the correct UK ring size before purchasing and advise on resizing options where necessary.

Any applicable resizing costs and timescales will be confirmed in advance.

Every CESTRIA piece arrives beautifully presented in its own premium branded jewellery box, carefully selected to complement the jewellery inside.

Whether you're purchasing a gift for someone special or choosing something for yourself, we believe the presentation should reflect the quality of your jewellery.

Where applicable, accompanying AGI documentation and insurance valuations are also included, ensuring everything arrives together and thoughtfully presented.

Your CESTRIA jewellery is carefully packaged and dispatched using a secure, tracked and insured delivery service.

For UK orders, we use Royal Mail Special Delivery, providing tracking, a signature upon delivery and insurance protection appropriate to your purchase.

You'll receive tracking details once your order has been dispatched. If your jewellery requires resizing or additional preparation, we'll advise you of the expected dispatch timescale.

We want you to feel completely confident when purchasing CESTRIA jewellery.
