A managed procurement service handling diamond inspection, consolidated shipping, payment, and returns.
White Glove Service is a managed diamond procurement offering that acts as a single window for quality control, shipment aggregation, payment, and returns. A third-party diamond grading team physically inspects each stone against buyer-specified criteria before dispatch. Purchases from multiple suppliers are consolidated into one shipment, and returns are accepted at the New York office regardless of supplier location.
Key accounts receive dedicated staff as a single point of contact across transactions. The service also carries supplier verification and compliance, giving buyers access to hundreds of vetted global suppliers without managing KYC directly. It serves diamond wholesalers, jewelry retailers, and jewelry manufacturers.
