OUR MANUFACTURING PROCESS

Our craftsmanship ensures each diamond's brilliance, clarity, and quality. Here's an overview of our step-by-step process:

SORTING

Our experts categorize the rough diamonds based on size, shape, and quality to strategize the best polishing approach.

CLEAVING & SAWING

Using precision tools, we execute the cutting process, either by cleaving (splitting) or sawing, to create smaller pieces known as "roughs."

BRUTING

We refine the rough diamond's shape by meticulously grinding away excess material from the edges. Then we use our bruting machines to shape the diamond into its fundamental form.
