Diamond Blockchain security

Blockchain Enabled Diamond

Traceability Recovery Suite

It is very difficult to recover lost or stolen high value diamonds as there is currently no standard practice out there to intercept stolen goods during resale. SecuLuxe aims to solve this problem.


Blockchain Enabled

Our solution utilises blockchain technology to create a highly reliable and immutable level of trust

between all involved parties.


Proprietary Nano-Engravings

Ground-breaking nano-laser markings are achieved via our superlens technology PCM

(Plano-convex microsphere lens).


Global Luxury Goods Recovery Solution

Our SecuLuxe network partners will be fully trained and located in Key locations around the world.


The Seculuxe Solution

Global Diamond-Marking Centres

We are currently the process of setting up global diamond-marking centres which will, in turn, allow us to onboard certified SecuLuxe partners who will be able to mark and add high-value goods to the SecuLuxe database.

Our selected SecuLuxe partners will implement generated IP using the Seculuxe platform, for full traceability, showing the diamonds origins, where it was mined, cut, wholesaled, purchased, but also to create a level of trust between Bespoke Jeweller’s, the consumer & Insurance companies. As a result It would also be invaluable as a recovery tool for high end Jewellery identification.


Pioneering solutions

Our Technology is constantly evolving

Working in collaboration with Diamond Centre Wales and SecuLuxe The CPE Bangor team, led by Dr James Wang have recently achieved laser engraving of diamonds with a unique code that is invisible to the naked eye. In the next stage of the project, we will be integrating the unique PCM superlens to try to achieve even smaller identification codes.


In an Optics Letters paper, published earlier this year, Yan and coworkers achieved minuscule laser engraved patterns with features as small as 350nm, well below the 800nm laser wavelength.

The heart of this low-cost nano-laser marking device is a new superlens design called PCM (Plano-convex microsphere lens). This consists of a standard plano-convex lens and glass microsphere with a 50 micron diameter that is encapsulated to the lens. This simple design enables large area complex designs to be made with improved reliability and repeatability compared with other microsphere-based laser fabrication techniques.


Initial research at Bangor University led to the development of a very quick and clean solution by using focused ultrafast laser pulses to write text and labels in variable size and shapes on any surface of the polished diamond sample. Several geometries were scribed on the diamond surface including QR codes, letters and text to simulate typical laser marked serial numbers as shown in the image. The size of the diamond is roughly 3x2x2 mm3.


The height of the text as shown by “DCW” is about 60 µm. The maximum depth of the laser machined line is 0.29 µm measured from surface plane of the untreated diamond. The results demonstrate a close agreement to the size requirements of the client to mark thin areas of polished diamonds such as girdle or crown. The pavilion marking shown in Figure as “CPE003-BU” is about 25 µm high (girdle height ~100 µm).

Complete Traceability and Transparency

As the industry turns towards a transparent supply chain, with full traceability of Raw Earth materials, Seculuxe Blockchain technology will become the new Industry standard.
