Small orders are being shipped via secure Fedex system, so even if you are in a motel location, the diamond will arrive within 24-48 hours.

We exist since 1992 and we buy our rough from leading dealers in the diamond industry. Onyx is focusing on delivering the product according to customer demand and creating an ongoing yearly supply to the customer, with the goal of becoming a regular supplier on a variety of products.

Due to the change in the industry in the last few years, we are witnessing less and less manufactures and regular suppliers of diamonds companies that will give fair services also to small and medium size orders. We try to fill the gap by proving size table to make it more easy on the customer to calculate himself the specific order and then call us for fine tuning the order according to stock availability and budget recommendations.
