The bench
01 / 04
01
Microscopic · permanent · tamper-proof
A very fine, precise laser beam etches tiny markings along the girdle — a stock number, a brand logo, a personal message, even a QR code. Invisible to the naked eye; clear under a jeweller's loupe.
02
For floating, feather-light settings
Tiny holes drilled through the stone let it hang on a thread or wire instead of a traditional setting — floating pendants and earrings with a clean, modern look. Done well, a white hole is tiny and hard to see.
03
Dark inclusions, removed
A laser channel reaches a dark inclusion — black carbon — inside the diamond so it can be removed, making the stone appear clearer. Often combined with fracture filling to enhance brilliance.
04
Non-thermal · no damage
A non-thermal polishing process that increases shine, durability and clarity. No heat at any point, so the diamond keeps its structure, its form and its brilliance.

Creating designs or photos in diamonds with a laser is a highly precise, intricate process. Detailed custom patterns, images and even text can be engraved on diamonds — otherwise hard to modify because of their hardness.

05 — The lab
Accurate · reliable · certified
We provide advanced testing to identify lab-grown, CVD, HPHT and natural diamonds with the highest level of accuracy. Using state-of-the-art technology and industry-standard gemological equipment, our experts give you complete confidence in your diamonds — loose stones or finished jewellery.
Every stone gets one answer
CVD diamonds look precisely like natural diamonds — which is why sophisticated methods of examination are needed to discern the truth about the stones.
Same chemistry, same light
Detection equipment
Spectroscopy, fluorescence and photoluminescence imaging — read by experienced gemologists and diamond graders.
Loose diamond testing
Diamond jewellery testing
Every piece is checked with high-precision instruments — even where stones are small or tightly set.

Laser inscription means using a very fine, precise laser beam to etch tiny markings on the surface of a diamond — usually along the girdle, the thin outer edge of the stone. These inscriptions are microscopic, invisible to the naked eye, and can only be seen under magnification, like with a jeweller's loupe.
Marking · 02
Creating designs or photos in diamonds using a laser machine is a highly precise and intricate process. The technique allows detailed and custom patterns, images or even text to be engraved on diamonds, which are otherwise hard to modify due to their hardness.
Marking · 03
Laser engraving and marking on jewellery — names, dates, messages and brand marks, sharp and permanent on the inside of the band.
Drilling · 04
White hole drilling refers to a tiny mark or pit drilled into a diamond for making jewellery. When the laser drills into the diamond it can leave a tiny, whitish hole at the entry point — this is called a white hole.
These holes are sometimes visible under magnification, like a 10× jeweller's loupe. A well-done laser drill is very tiny and hard to see; careless work leaves bigger, more obvious white holes. White holes are different from natural imperfections — they are a man-made feature, and can slightly affect a stone's value.
Drilling · 05
Small holes are created using lasers to remove dark inclusions — internal flaws such as black carbon. Laser drilling removes visible inclusions, making the diamond appear clearer.
It is often combined with fracture filling to enhance brilliance.

At Super Diamond we excel in the cold diamond polishing process — a sophisticated, non-thermal polishing procedure for increasing the shine, durability and clarity of diamonds. Our cold luster treatment is popular among jewellers, manufacturers and diamond traders who need a flawless, brilliant finish without compromising the stone's integrity.
A new method in the diamond industry for precise surface polishing. Unlike conventional treatment processes, it uses no heat whatsoever — so the diamond does not lose its brilliance, its form and, most importantly, its beauty.
