Wholesale Diamond Buying Guide
Sourcing loose diamonds in bulk requires a solid procurement workflow. Whether you operate a regional retail boutique network or a high-volume jewelry manufacturing line, partner with a direct diamond manufacturer to reduce costs and maintain inventory consistency.
Direct Factory vs Intermediary Suppliers
Buying from a diamond wholesaler or broker adds intermediary markup costs. Working directly with a diamond manufacturer like TR GEMS gives you access to factory-direct pricing and custom sorting capabilities.
Establishing Your Sourcing Criteria
- Sieve Sizes: Specify diameter limits (e.g. 1.0mm - 1.5mm) for pavé layouts.
- Assortment Consistency: Define color bases (e.g., G-H) and clarity tolerances (e.g., eye-clean VS2).
- Regulatory Proofs: Confirm Kimberley Process compliance sheets accompany the parcel.
Frequently Asked Questions
How are wholesale diamond prices calculated?
Wholesale diamond prices are calculated using the Rapaport Diamond Report index as a benchmark, adjusting for parcel size, cut consistency, and trade payment terms.
What is a calibrated parcel?
A calibrated parcel is a lot of loose diamonds sorted to match in dimensions, color, and clarity, allowing jewelry manufacturers to set stones directly in mass-production lines.
