What You Get With a Trade Account
Browsing our stock table is open to everyone, and pricing is publicly visible. Registering for a trade account unlocks the benefits that matter when you’re ready to do business with OCS Diamond:
Order access — Browse-only visitors cannot place orders; a registered trade account allows you to proceed with purchases.
Dedicated support — You’ll have a direct point of contact on our team instead of relying on a general inbox.
Priority response — Registered trade accounts receive responses to inquiries within 24 hours, subject to order complexity and inquiry volume.
Registration is free and creates no long-term commitment. You can start with a single sample order before deciding whether OCS Diamond is the right fit for your ongoing sourcing needs.

Not sure which payment method fits your order? Our team will recommend the right option based on order size and relationship stage during your inquiry.
Escrow vs. Letter of Credit
If you’re unfamiliar with the difference: escrow is a neutral third party that holds your payment until you confirm the stone arrived as expected, then releases funds to us — faster to set up, well suited to smaller or first orders. A Letter of Credit is a bank-issued guarantee, more common for larger or repeat trade orders, with your bank releasing payment once shipment documents are verified. Neither is “better” – they suit different order sizes and levels of familiarity between buyer and supplier.
