High Risk Warning from Google When Making a Purchase
There is no need to worry if you encounter a high risk alert when making a purchase. This is an additional security measure imposed by Google to prevent any unauthorized or unintended high value transactions. Google may _keep_ this temporary transaction in your payment account. However, this temporary transaction will be erased automatically.
Meanwhile, please check carefully that the billing address and name filled out for your Google+ account at wallet.google.com matches that on your credit card.
If you continue receiving _High Risk_ alerts when purchasing diamonds, please contact Google for further assistance.
