Chain Styles & Lengths

Every locket is paired with your choice of three beautifully crafted 18 carat gold vermeil chain styles, each available in four lengths to suit your neckline and personal style:

Curb Chain — a classic, flat-linked style with a clean, polished look, available in 18 inch (46 cm), 20 inch (50 cm), 22 inch (56 cm) and 24 inch (61 cm).
Rope Chain — a twisted, multi-strand design that catches the light beautifully, available in all four lengths.
Belcher Chain — wide, rounded links with a luxurious weight and presence for a bolder, more substantial look, available in 18, 20, 22 and 24 inch lengths.

All chains are crafted in 18 carat gold vermeil, the same premium finish as the locket itself, ensuring a perfectly coordinated, high-quality piece from bail to clasp.

Frequently Asked Questions

Is this a large or small locket?

This is a large, statement locket measuring 30 mm in height (including the bail) and 20 mm in width, making it noticeably bolder and more substantial than a dainty everyday locket. It is designed to be worn as a centrepiece piece rather than layered. If you are looking for something more delicate, our bestselling 2 Photo Diamond Heart Locket measures 16 mm wide by 21 mm high.

Is this locket made of solid gold or gold vermeil?

This locket is crafted from 18-carat gold vermeil, which is a thick layer of real 18-carat gold bonded over a solid 925 sterling silver base. It is independently tested and hallmarked by the Edinburgh Assay Office with a full UK hallmark. Gold vermeil offers the luxury and warmth of solid gold at a more accessible price point and is a premium, hypoallergenic choice.

Is the diamond in this locket real and ethically sourced?

Yes. This locket features a real, natural diamond set in the top right corner of the heart. All diamonds in our jewellery are ethically sourced and conflict-free, fully compliant with the Kimberley Process and United Nations Resolutions. An ethical diamond certificate is included with every locket.

Is this locket hallmarked?

Yes. This locket carries a full UK hallmark independently verified and stamped by the Edinburgh Assay Office, confirming the metal purity and quality of the piece. Lily Blanche is a proud member of the National Association of Jewellers.

Is this large gold diamond locket worth the price?

This locket is crafted from 18-carat gold vermeil over a solid 925 sterling silver base and features a real, natural, conflict-free diamond. It is independently hallmarked by the Edinburgh Assay Office — the same assay office used for solid gold jewellery — and is designed to last a lifetime with proper care. Compared to a solid gold equivalent, gold vermeil offers the same luxury appearance and hypoallergenic properties at a significantly more accessible price point. It is a considered purchase designed to become a family heirloom, not a fashion piece.

Where is this locket designed and made?

This locket is designed in Lily Blanche's studio in Scotland and crafted in 18-carat gold vermeil. Every personalised order is hand-finished by our studio team in Stirling, who edit, print, and fit your photographs and precision-engrave your message before shipping. Lily Blanche is a Scottish jewellery brand, a member of the National Association of Jewellers, and an award-winning designer. All lockets are independently hallmarked in the UK by the Edinburgh Assay Office.

Can the reverse of the locket be engraved?

Yes. A name, date, or meaningful message can be engraved on the reverse of the locket as part of our personalisation service. Please note that engraved items are non-returnable.

How long does it take to make and deliver this locket?

Standard UK delivery is free on orders over £125 and typically arrives within 2–3 working days. Please allow an additional 1–2 working days for personalisation. If you need your locket sooner, next working day express delivery is available for orders placed before noon. International delivery options are available at checkout. All orders are sent fully tracked and you will receive tracking details via email.

Is this large gold diamond locket a good anniversary or milestone birthday gift?

This locket is one of the most popular grand gesture gifts in our collection, chosen as a significant wedding anniversary gift, a 30th, 40th, or 50th birthday gift, a retirement gift, or a meaningful heirloom keepsake for a daughter or wife. It arrives in a ribbon-tied gift box with luxury packaging at no extra cost, ready to present.
