gold electroplated, YGF or yellow gold filled, RGP
or rolled gold plated, etc.) and then if when tested
the results indicate anything to the contrary, the
metal should be suspect. Test results below the 10K
range must be interpreted by the user and estimated
whether it is 6K-9K. In the UK while 9K gold may be
found, gold below this karat range is extremely rare,
and the gold content is minimal. If it tests in a lower
karat than 9K or in a lower karat than is marked, it is
advised to simply not buy it.
GUIDELINE B.
Be aware that any piece that tests as
NA is not gold.
GUIDELINE C. Check the weight of the metal you
are about to test and if it seems too light, it should
be suspect. Gold is a dense metal and has an
associated greater weight than most other non-
precious metals. Platinum is an even denser metal
than gold, while weighing approximately 1/3 more
than 18K gold.
GUIDELINE D.
Check the color of the gold, since
non-gold substitutes are often flashed or plated with
24K gold to enhance its color and consequently the
gold will look too yellow. Since 24K gold is a rich
yellow color and this pure gold is very uncommon in
jewelry, any rich yellow gold color should be suspect.
Look for tarnishing or variations in the color and finish
of the jewelry as a sign of it being a fake.
GUIDELINE E. Check the clasp used on the jewelry.
Costume jewelry often has a spring ring style clasp
and this should be suspect. Karat jewelry more often
than not will have a lobster style clasp. Do not test
the clasp only as it is common for a karat gold clasp
