In this world of advanced technology it is
almost impossible to simply look at a
diamond and determine whether it is real or
not – especially if you don't know much
about diamonds. There are some steps that
you can take to avoid buying a fake diamond,
however.

First, only deal with reputable jewelers, and
when you find a reputable jeweler, stick with
them. Avoid buying diamonds or other
jewelry from jewelers that you have never
dealt with before in the past. Ask to see the
certificate for the stone. If no certificate exists,
walk away.

Look at the setting that the stone is in. Fake
diamonds, such as zirconias, are usually set
in low quality metals. Take a close look at the
stone. Fake diamonds are not durable –
natural diamonds, on the other hand, are the
most durable stone on the planet. Look for
scratches or nicks.

After purchasing a diamond, take it to
another jeweler for appraisal. In fact, take it
to two or three other jewelers for an appraisal
to make sure that the appraisals are all fairly
close. If you find that you have purchased a
fake diamond, you may be accused of
making a switch when you return to the store
of your purchase; therefore, it is important to
have a certificate for the diamond. No two
stones are alike.
