I offer gift certificates
in denominations of $5, $10, and $25.
Here is a photo of one of
them:

Upon purchase of your gift
certificate, you or your recipient will be mailed a physical gift
certificate to be mailed back to me when she/he wants to use
it.
This
warning is just for those very few people who are
dishonest. The reason for
mailing a physical certificate is that there is an anti-theft
device on the certificate. If any part of the certificate
is tampered with, I will know about it and that will render the
certificate worthless. In addition, I keep track of the
name address and phone # of the purchaser AND recipient of these certificates
and WILL call them if I think there is something
wrong.
The To: and From: spaces
must have your name AND the recipient name,
along with a phone number for both, even if both names are the same.
Your certificate will be
dated a year ahead so there will be plenty of time for the recipient to
make a choice. I generally add new jewelry to my site on a
weekly basis so keep checking back here.
