I did this project while I was working at ONIO Design Pvt. Ltd. as an Industrial designer.
The product is launched in the market.

DRC Techno is a subsidiary of Dharmanand Diamonds Pvt. Ltd., a leading global diamond manufacturer in Surat, India. DRC Techno specializes in product innovation and manufacturing of important instruments for the diamond and jewelry industry. From CNC diamond cutting machines to gemological research and development of accurate identification, evaluation, and assessment of diamonds.

Synthetic diamonds or lab-grown diamonds are a serious threat to the diamond and jewelry industry. They cost about 30-40% less and are nearly identical to naturally occurring diamonds as the chemical composition is the same. This makes them show up as positive on diamond tester machines. To ensure safe and fair practices free of contamination in the diamond manufacturing to jewelry end-product pipeline, DRC pioneered a scanning instrument that can detect synthetic diamonds in all sizes (0.003 Cts - 10 Cts) and shapes.​​​​​​​
DRC was working on first-ever "mounted diamond jewelry detector". It can detect lab-grown diamonds from a set of mounted diamonds in necklaces, bangles, and rings.

DRC needed a well-stylized enclosure for their diamond jewelry scanner, J.Secure, and an unset diamond scanner, D.Secure, with the smallest possible footprint. The design language had to be consistent across varied enclosure dimensions. And also to redesign the imaging interface for the machine.

Client designed mechanism
DRC approached us with a prototype of the machine which was a simple arrangement of a scanning bed mounted on two X and Y-axis linear motors with an overhead camera. 
The entire enclosure was about 3 feet X 3 feet X 3 feet and had to be mounted on a similar-sized pedestal with castors.

Client-side machine prototype

The choice of mechanism was simple and efficient from the point of view of standardization but needed too much space, substantially adding to the overall footprint of the enclosure. We envisioned the enclosure from the point of view of a desktop product that won't take up too much space in the busy offices and shops of diamond merchants in the Indian scenario.
Client-side interface
The client asked us to use the earlier D-Secure interface as a starting point. This interface was being used for their loose diamond scanning machine.

Client-side interface for loose diamond scanning machine

While the client only wanted us to quickly design a well-stylized enclosure, I couldn’t help but notice the massive footprint of the machine in the context of the end customer.

I identified two potential customer profiles for this machine, a diamond trader and a retail store, along with their respective needs and expectations from a machine like this. 
I proposed a different solution. Instead of mounting the scanning bed on the x, and y-axis, I instead chose to use a cylindrical shape for the scanning bed on a rotary axis. A cylindrical scanning prop leaned itself well to structured jewelry which would not rest completely on a flat scanning bed. The camera was mounted on a single z-axis. Just two axes were sufficient enough to cover the entire scanning area.

The redesigned schematic was prototyped on the client side for feasibility and it worked as expected!

The redesigned hardware schematic enabled the machine to be small enough to fit on a tabletop! My proposed mechanism achieved a 50% reduction in enclosure footprint, a 200% increase in the scanning surface area, and requiring 10% less hardware. This meant you could scan more jewelry in less time.
The entire enclosure was CNC milled in Aluminum with a premium anodized finish for longevity.
A custom-designed pattern was milled on the side panels to reflect the nature of the industry and customer affinity towards more ornamental styling.
I first did a UX audit of the interface and identified multiple issues with visual design and usability.

I worked with the marketing director on the client side to understand key customer use cases.
And we identified two main use cases which is buying and selling. While both use cases had similar processes, in the case of buying the focus is more on scanning and in the case of selling the focus is more on generating reports.

 We identified some processes that were unique to this machine to the diamond scanner :

Intertwined physical and digital processes :
After the scan is completed, the user needs to pull out the prop and correlate the scan results with the jewelry placed on the prop.
Preview function:
Scan results can be of 3 types, all pass which is no cvd diamonds detected, some positives, and recheck.
In the case of recheck, when the jewelry is inserted back in for rescanning, the user may not want to auto-scan the whole prop but instead jump to a specific point on the grid and only scan that. 
I then gathered all the different interface functions that I needed to design for. The ones highlighted in blue were unique to this interface.
This was the final proposed interface, and you can see the before and after, with a much cleaner and consistent design.
 Right on top, you have your job details which update automatically after each scan.
Overlaid on each cell of the grid is the cell number along with the scan details, which are greyed out until you make a scan, and then they display color-coded information.
At the bottom is the grid scroll function, and the cta field is aligned to the right. 
And you have 2 different grids for larger jewelry like necklaces and chockers and a higher resolution grid for bangles and bracelets.
