Looply Authentication
Jewelry authentication, in detail
A closer look at the form, craftsmanship, markings, and material analysis behind each piece of jewelry.
Jewelry
We bring together the piece’s form, markings, craftsmanship, and material-analysis results. Numbers and documents are checked for consistency with the piece.
Form & craftsmanship
We examine shape, proportions, and design details. Under magnification, we inspect the settings, polished surfaces, and soldered joints, comparing the construction and finish with the expected workmanship.
For the rounded motif shown here, the fullness and consistency of the individual lobes form part of that examination.
Authentic reference
Counterfeit reference
Hallmarks & maker’s marks
We examine the logo, metal marks, serial number, and maker’s mark where present. Their shape, placement, and engraving are compared with the design and production period.
In this example, the letters D, PS, and STE sit around a diamond-shaped maker’s mark. We compare their layout and clarity with the expected marking.

Precious-metal composition
We use instrument-assisted analysis to check precious-metal composition and compare the results with the piece’s material markings. These findings support the hands-on examination of the markings and construction.

Numbers, documents & condition
Production-period consistency
We cross-check serial numbers and other markings against the design and production period. Number formats can vary by collection and era, so they are assessed as part of the wider inspection.
Documents & accompanying items
When included, we review warranty cards, certificates, boxes, and other accessories. We examine paper, printing, and security markings, then compare the information with the piece, including relevant production and sale dates.
Wear, polishing & previous work
We look for wear, polishing, maintenance, and replaced parts. We record previous work we identify and document the piece’s condition.

The full assessment
What the findings tell you
Our specialists review the physical details and technical findings together, with AI analysis supporting their assessment. They make the final authentication decision.
Wear, repairs, alterations, and functional findings are documented separately. Your item’s digital Looply Certificate of Authenticity records the authentication result alongside condition information, linked to its unique authentication number.
