Introduction
When purchasing pre-owned
jewellery in London, authenticity and quality matter just as much as
beauty. Whether you’re investing in a diamond ring, a vintage gold necklace, or
branded designer jewellery, knowing that the piece is genuine is essential.
At Preowned Luxuries in Hatton
Garden, our experienced jewellery specialists carefully authenticate every
item before it reaches our display cases. Located in the heart of London’s
historic jewellery district, our store serves clients from Camden,
Clerkenwell, Farringdon, and across Greater London who want high-quality
pre-owned luxury jewellery they can trust.
In this guide, we take you behind
the scenes to reveal how each piece is authenticated and prepared before
being offered for sale.
Step 1: Initial Jewellery Assessment
Every piece begins with a
professional inspection by our jewellery experts.
During this stage we evaluate:
- Gold purity and metal hallmarks
- Overall craftsmanship
- Condition and wear
- Original brand markings
- Stone settings and mountings
This first assessment determines
whether the item meets our strict quality standards before moving on to deeper
verification.
Step 2: Diamond and Gemstone Testing
Diamonds and gemstones are examined
using professional gemological tools to confirm authenticity.
Our London specialists check:
- Diamond clarity and colour
- Carat weight and cut quality
- Natural vs synthetic gemstones
- Refractive index testing
- UV light and microscope inspection
This ensures every diamond ring, necklace, or bracelet sold in
Hatton Garden is genuine and accurately valued.
Step 3: Hallmark and Metal Verification
The UK has one of the strictest
hallmarking systems in the world. We verify all hallmarks carefully to confirm
metal purity.
Our testing confirms:
- 9ct, 14ct, 18ct, or 22ct gold
- Platinum authenticity
- Vintage and antique hallmarks
- Maker’s marks and brand stamps
When required, additional metal
testing equipment is used to ensure the accuracy of each piece before it enters
our inventory.

of scrutiny.
Our experts verify jewellery from
well-known houses such as:
- Cartier
- Tiffany & Co.
- Bulgari

Authentication includes checking:
- Serial numbers
- Signature engravings

every piece undergoes careful restoration.
This includes:

- Stone tightening if needed
- Minor restoration work
Our goal is to present each item in
excellent wearable condition while preserving its character and value.
