Our Excellence

Jewellery Manufacturing Process

From concept to creation, every piece goes through a meticulous 11-step process ensuring the highest quality standards

Step 1

Designing

Jewellery starts with a concept or sketch. Created manually or using software like Rhino or MatrixGold. Final design includes size, weight, stone placement, and details.

Step 2

3D Modeling

Design converted into a 3D model. A wax model is made using 3D printing (CAM) for perfect accuracy.

Step 3

Wax Model Making & Casting

Wax model is created and attached to a wax tree. Covered with plaster and heated to remove wax. Molten gold is poured into the mold. This process is called lost wax casting.

Step 4

Cleaning & Cutting

After cooling, the mold is broken. Individual jewellery pieces are cut from the tree. Rough surfaces are cleaned and prepared.

Step 5

Filing & Pre-Polishing

Extra metal removed using tools. Surface smoothened. Basic polishing done to prepare for stone setting.

Step 6

Stone Setting

Diamonds or gemstones are fixed using various techniques: Prong setting, Bezel setting, or Pave setting.

Step 7

Final Polishing & Quality Check

High-quality polish for perfect shine using buff polishing and Rhodium plating (for white gold). Weight verification and stone security check performed.

Step 8

Hallmarking & Finishing

Certified by Bureau of Indian Standards (BIS) for purity. Final cleaning and premium packaging completed.

Step 9

Final Quality Check

Comprehensive final inspection before shipping to ensure every piece meets our perfection standards.
