About Second-Hand Fine Jewellery

Explore authenticated second-hand fine jewellery in gold, platinum, diamonds and gemstones. This collection focuses on precious materials, with metal, hallmarks, stone or setting details, measurements, condition and exact inclusions documented for each individual piece where available.

The Lost Designer standard

Second-Hand Fine Jewellery in Australia

Explore authenticated second-hand fine jewellery in gold, platinum, diamonds and gemstones. Unlike the broader designer jewellery catalogue, this collection is focused on precious materials, with metal, hallmarks, stone or setting details, measurements, condition and exact inclusions documented for each individual piece where available.

Each fine jewellery piece is reviewed by two authenticators and authenticated through LegitApp. We inspect the metal, hallmarks, engravings, settings, stones, clasps and construction where applicable, then document condition and wear with detailed descriptions and clear photography.

This fine-jewellery collection is distinct from the broader designer jewellery edit: it is centred on precious metals, diamonds and gemstones. Compare the stated metal, hallmarks, stones or settings, measurements, condition and exact inclusions on each individual listing.

How to compare pre-owned pieces

Second-Hand Fine Jewellery buying guide

Frequently asked questions

What is checked on pre-owned designer jewellery?

The individual piece is reviewed by two authenticators and authenticated through LegitApp. Materials, hallmarks, engravings, construction, settings and other identifying details are considered where applicable, and a physical authenticity certificate is supplied.

Read our authenticity promise
How is the condition of each fine jewellery piece assessed?

Pre-owned jewellery is assessed for metal wear, hallmarks, engravings, clasps, fastenings, settings, stones, chains and links where applicable. We identify visible scratches, tarnishing, dents, plating wear, repairs, alterations and resizing where these can be determined from the individual piece.

Does each fine jewellery piece include its original box or paperwork?

Every pre-owned jewellery piece includes a physical authenticity certificate from Lost Designer. Original box, pouch, brand certificate, receipt, care booklet and service or repair documentation vary by item and are included only when listed on the individual product page.

What counts as fine jewellery in this collection?

This collection focuses on pieces made from precious metals such as gold or platinum and may include natural diamonds or gemstones. The exact materials and stone details available to us are stated on the individual product page; we do not assume specifications from the style name alone.

Can I inspect a fine jewellery piece at the Toorak boutique?

Yes. Visit us at 428E Toorak Road, Toorak during opening hours. No appointment is required, although one-of-a-kind pieces can sell at any time.

Plan your visit
Are orders tracked and insured in transit?

Yes. Every item we dispatch is tracked and insured in transit. We offer complimentary express delivery across Australia, with orders dispatched from our Toorak boutique within one business day, excluding weekends and public holidays.

View delivery information
Can I purchase a fine jewellery piece using lay-by?

Yes. Secure your item with a 20% non-refundable deposit, then pay the remaining balance across four fortnightly instalments over eight weeks. There are no interest charges or account fees, and you can pay early.

View lay-by terms
What happens if an item arrives not as described or raises an authenticity concern?

If an item is materially not as described, contact us within seven days of delivery with photo or video evidence. If an item is proven inauthentic, we provide a full refund including return shipping. Change-of-mind returns are not accepted.

View delivery and returns
What details should I compare before buying second-hand fine jewellery?

Compare the metal and hallmark information, dimensions or size, stone and setting details where applicable, visible condition, repairs or alterations where identifiable, and the exact box, certificate, receipt or valuation documents included with that individual piece.
