Perfection isn’t an accident—it’s a discipline. At DVN Jewelry, every gold piece passes through a rigorous quality control system designed to guarantee flawless craftsmanship, durability, and consistency. From raw gold to the final polished masterpiece, DVN’s manufacturing team follows a detailed workflow to ensure every product meets global standards of excellence.
Below is a step-by-step look inside DVN’s quality assurance process.
1. Raw Material Verification: Purity Comes First
DVN begins with strict inspection of gold purity, ensuring karat accuracy for 9K, 14K, 18K, and 22K alloys.
-
Every batch is XRF-tested to verify metallurgical composition.
-
Only certified and traceable gold material enters the production line.
This prevents contamination, impurities, and inconsistent color tones.
2. Alloying & Melting: Controlled for Uniformity
Gold is combined with other metals to create the correct karat.
DVN follows:
-
Precise temperature control
-
Computer-guided melting
-
Proper alloy-to-gold ratio
This ensures consistent hardness, color, and durability in every piece.
3. Casting Inspection: Perfect Foundation
Before polishing or detailing, the cast piece undergoes:
-
Porosity checks
-
Surface smoothness inspection
-
Internal defect detection using basic NDT methods
DVN rejects any casting with visible or hidden flaws to maintain strength and finish quality.
4. CNC & Laser Precision Check
DVN uses advanced CNC machining and laser technology to create perfect patterns, engravings, and structural details.
Quality control at this stage includes:
-
Pattern depth measurement
-
Symmetry and alignment check
-
Edge precision inspection
This ensures clean lines, exact dimensions, and uniform designs across batches.
5. Soldering & Welding Integrity
Every join is tested for strength and durability.
DVN ensures:
-
Clean, invisible solder joints
-
High-strength laser welds
-
Zero porous seams
This prevents breakage and enhances long-term wearability.
6. Handcrafting Excellence: Skilled Artisan Review
Even with machinery, human craftsmanship is irreplaceable.
DVN artisans:

No scratches
-
Even reflection
-
Smooth edges

Consistent surface texture
The result: high-gloss perfection in every jewelry piece.
8. Final Inspection & Approval
Before packaging, each piece is reviewed under magnification:
-
Weight verification

Karat stamping accuracy
-
Structural balance
-
Lock and hinge testing (for bangles, bracelets, etc.)
Only after passing the final QC does the piece receive the DVN approval mark.
9. Secure Packaging & Dispatch
DVN ensures that perfection is maintained until the product reaches the customer.
Packaging is designed to:
-
Protect delicate surfaces
-
Maintain shape and polish

Prevent moisture and scratches
