NOTE: These solutions will dull the polishing of the piece, and

TESTING FOR GOLD
1. Scratch the piece to be tested over the surface of a
testing stone press firmly, leaving a visible deposit,
preferably a line 1'' long.
2. Add a drop of the 10K solution to the scratched area.
If the solution dissolves the scratch on the stone, the
object is less than 10K gold or not gold at all. If the
solution leaves the scratch intact, the object is 10K
gold or greater than 10K gold.
3. Repeat the scratching and testing with the 14K
solution. If the solution dissolves the scratch on the
stone, the object is less than 14K gold (if the scratch
dissolves slowly and leaves rusty color particles, it is
probably 12K gold). If the solution leaves the scratch
intact, the object is 14K gold or greater than 14K.
CAUTION: Many objects are marked 14K, but were
fabricated prior to 1982 when it was legal to mark
items 14K, but in reality, the gold was 13.5K. When
testing 13.5K gold, the 14K solution will not dissolve
the scratch, but it will make the scratch lose its
brightness, making it turn a yellow-rusty color.
4. Repeat the scratching and testing with the 18K and
22K solutions (if available) to determine the karat of
the object. When the solution dissolves the scratch
slowly and leaves rusty color particles, the tested
piece is probably two karats lower than the solution
being used. For accurate testing, we recommend that
the user becomes familiar with comparative testing
using standard gold testing needles.
Note: Heavyweight items such as chains and coins may
be plated. Make a deep notch in the piece and perform
testing on the metal inside.
TESTING FOR SILVER
Simply scratch the test stone with your jewelry and apply a drop of the silver acid solution to the stone and watch the results appear! The color reaction of the solution on the jewelry will be as follows:
90%-100%= Creamy color
77%-90% = Gray color
65%-75% = Light Green color
TESTING FOR PLATINUM AND WHITE GOLD
Transfer a drop of the platinum test solution to the jewelry. If the area stays a white, bright color, it is real Platinum. Platinum test liquid can also be used for 18k and 14K white gold. In the case of 18K, the solution on the jewelry should start changing to a light bronze color in about 3 minutes. For 14K white gold, the solution on the
jewelry should disappear in about 15 seconds!

CAUTION
Use extreme care in handling gold and silver testing solutions, for they are, corrosive acids. Always wear gloves when testing. In case of skin contact, flush with large amounts of water. Then treat the affected areas with sodium bicarbonate or baking soda. If swallowed, contact a physician or hospital at once. In the case of spills, treat with water and then sodium bicarbonate or baking soda.
