Payment from bank to bank only.
Why?

Diamonds are the most valuable items among all commodities. It is an ancient tradition in the world of diamonds that payment comes before delivery. We do not accept credit cards and do not offer payments over the Internet.

There is a good reason for this:
Your order and your payment are exclusively your and our business. We consciously want to protect you from leaving unnecessary marks online and want to exclude additional confidants. For reasons of data protection and the protection of your discretion, we therefore only offer direct payment from your bank to our bank. We think we have acted in your interest and thank you for your understanding.
