Prices will be agreed on sight for both rough and cut stones, however a price on cut stones can usually be agreed at discount on Rapaport prior to sight.

Gold 黄金
  GLD (12.5kg hallmarked bullion) and some Dory bar (1kg bar for jewellers) will be set at a discount below the 2nd fix on the London Exch. The discount will could be something like 8% Gross / 6% Net , with the 2% being split amongst the intermediaries with each party, buyer and seller contributing 1% each.
  With gold dust and nugget the metal has to be refined to prove purity of at least 99.999 and this is usually done in the buyers refinery of choice. On assay the refinery releases a certificate of purity and the buyer authorises payment bank-to-bank. (If cyanide has been used in the extraction process, this may need to be removed from the dust before refineries will handle it
  The procedures for gold are fairly standard regardless of the state of the metal (although procedures vary deal to deal).

• 1. Seller issues Full Corporate Offer (FCO) to buyer stating commodity, form, fineness, delivery time, origin, etc.
• 2. Buyer responds with Letter of Intent (LOI) agreeing to or amending the procedures and specifying delivery location.
• 3. Buyer provides proof of blocked funds and conditional swift order (conditional on assay certificate).
• 4. Contracts are drawn and signed by buyer and seller ( this includes the Fee Protection Agreement (FPA) for the intermediaries)
• 5. Gold sent to refinery (or if GLD then bank-to-bank safekeeping receipt need only be exchanged) and a certificate of purity is released
• 6. Buyers bank releases swift payment to sellers bank and pays intermediaries at the same time.
