Single invoicing and payment in Canadian currency

You will receive only one invoice per order, which will include all duties and taxes.

  • All payments should be made in the currency on the invoice to avoid exchange rate fees.
  • While placing an order and paying with a credit card, a Stuller consultant will verify the currency of the charge.
  • All Canadian payments will go to this address:
    PO Box 15557, Station A
    Toronto, Ontario M5W 1C1
  • Only Visa and Mastercard are accepted.

Payments sent to another Stuller address will prolong the process and could result in finance charges and fees.


Your extended order cutoff time is 3:00 p.m. (your local time). This means that no matter where you are located, you can place your order until 3:00 p.m. with next-day delivery.

Canadamark Diamonds

Canadamark Diamonds

Canadamark introduced the diamond industry to a new level of transparency with melee that can be tracked, in batches, from mine to market. These make the ideal choice for customers who want to know the origin of their melee and complements a Canadamark center stone perfectly.
