Rough Miners' Diamonds from Kimberley Mine
These are unworked miners' diamonds extracted directly from primary diamond mines like Kimberley, featuring irregular shapes and natural inclusions typical of rough industrial-grade stones. Classified under HTS 7102.21.10 as miners' diamonds, which are specifically diamonds in the natural state from mining operations, not subjected to sawing, cleaving, or bruting. They are primarily used in industrial applications such as drilling and cutting tools due to their hardness.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sorted by size or hand-sorted into categories
Miners' diamonds become 'other unworked or simply sawn, cleaved or bruted' under 7102.21.30 once sorted, no longer in raw mined state.
If simply sawn, cleaved, or bruted for industrial use
Processing beyond natural state like basic cutting moves them from miners' diamonds to worked industrial diamonds in 7102.29.
If suitable for industrial use but further processed or synthetic
Diamonds not qualifying as natural unworked miners' fall under synthetic or reconstructed industrial diamonds.

Import Tips & Compliance
• Verify origin certificates from recognized mines to confirm 'miners' diamonds' status and avoid reclassification as sorted rough diamonds
• Provide geological assay reports documenting natural unworked state, as any processing like sorting by size may shift to 7102.21.30
• Declare exact weight and caratage accurately; common pitfalls include undervaluation leading to audits on industrial vs gem-quality distinctions
