Sourcing diamonds at a B2B level requires alignment between rough purchasing, laser plotting, faceting, and logistics. Let's look at how commercial diamond sourcing works at TR GEMS.

Sourcing Rough Diamonds

Our sourcing team acquires ethically mined rough diamonds from partner miners, confirming that each rough parcel complies with the Kimberley Process.

Precision Polishing and Grading

Rough diamonds undergo laser scanning to plot inclusion maps. We polish the stones at our Surat facilities to maximize yield and sparkle before submitting them for grading.
