Demantur mitti GIA númer laser leturgröftur vél heit selja
Once a diamond reveals its fire, það á skilið auðkenni sem passar við ljómi þess. Hefðbundnar aðferðir skortir: vélrænni leturgröftur hætta á sprungum, hægt er að þurrka blekmerki af, og hitaleysir geta valdið gulnun eða bruna. Even the slightest flaw can cost a top-tier gem millions in premium at auction. Now, meet the solution that replaces force with finesse: the UV Diamond Marking Machine. Using a 355nm cold laser source, it etches a micron-level permanent mark on the diamond’s girdle—without structural damage, without altering dispersion, and beyond forgery. From mine to market, it provides a traceable, verifiable “hardcore passport” across the entire supply chain.
Technical Depth
- Cold Processing Principle – Photochemical Ablation Over Thermal Melting
The 355nm UV laser delivers single-photon energy as high as 3.5 eV, directly breaking the C-C bonds on the diamond surface for clean, gaseous removal. With a heat-affected zone of <1 µm, the process eliminates thermal stress and micro-cracks. GIA inspection reports confirm “zero burn marks, zero dispersion change.”
- Micron-Level Precision – Where Detail Defines Premium
On a girdle as thin as 0.02 mm, the machine can engrave a 0.05 mm × 0.05 mm DataMatrix code. Individual characters are just a quarter the width of a human hair—crisp and sharp even under 10x magnification. Ideal for discreet branding: Logos, certificate numbers, or private signatures.
- Permanent Anti-Counterfeiting – Dual Physical + Digital Security
The laser induces random nano-textures that cannot be polished away. Each code is synchronized with a blockchain certificate, allowing instant scanning to reveal origin, cut, fluorescence, and auction history. Truly, “one object, one certificate, one code for life.”
Core Advantages
- Zero-Damage Guarantee
Batch-tested by the National Gemstone Testing Center (NGTC), diamonds show no change in clarity, color grade, or fluorescence intensity before and after marking. Insurers directly accept the “no damage” report, maintaining original premium rates.
- One-Time Investment, Lifetime Anti-Counterfeiting
The machine supports 24/7 continuous operation with MTBF >30,000 klukkustundir. Marks resist acid, alkali, and annealing at 800°C—lasting a lifetime without fading. Eliminates recurring costs for re-tagging, re-certification, and re-inspection.
- Invisible Yet Aesthetic
With a focused spot size ≤10 µm and engraving depth of 50–150 nm, the mark is invisible to the naked eye and doesn’t interfere with light entry or brilliance. Only visible under 20x magnification—balancing discreet branding with professional traceability.
- Multi-Format, Multi-Language, Multi-Material
Supports TrueType, OCR-A, DataMatrix, QR, and DM codes; Enska, numerals, Simplified Chinese, Russian, Hindi, og fleira. Works not only on diamonds but also on ruby, sapphire, moissanite, CVD lab-grown diamonds, and other hard crystals.
- Production-Line Efficiency
Dual vision positioning + rotary fixture enables 360° girdle marking in one go. Speeds up to 1.2 seconds per stone; integrated with automatic sorting systems, shifts yield 8,000–10,000 stones—meeting high-volume demands in Surat and Guangdong.
Application Scenarios
Diamond Processing Plants – Engrave internal batch codes for end-to-end traceability, reducing mix-up and substitution risks.
Jewelry Brands – Encode logos and website links into micro-marks; customers scan to enter brand story pages, boosting loyalty and repeat sales.
