Distinguishing the Different "Karat" in Gold

How to Distinguished the different "KARAT" in GOLD

For preparation you need the following:

Test Stone, a dark stone, used to test gold karat as well as silver and platinum. The object to be tested is scratched on the surface of the stone and a test acid solution determines the karat of the scratch.


Bottle of Nitrics Acid, also know as aqua fortis and spirit of nitre, acid for gold testing.
Cigarette Ashes and Water

Steel Sand Paper (Fine), alternative way to distinguised if the metal is pure gold or gold filled
Small Trangle Shaped File or "KIKIL", another alternative way to test the metal if its pure gold or gold filled

Here's the Procedure:

Rub the metal to be tested on the test stone and leave a very distinct GOLD DEPOSIT on it. Pour nitric acid on the half portion of the gold deposit and the other half as is and see any changes in color between the two for a few minutes.

If the color changes into REDDISH its 10 kt, LIGHT RED is 12 KT, YELLOWISH GOLD its 22kt. If the gold deposit is totally dissolved by the nitric acid, the metal does not contain any part of pure gold, therefore, it is NOT GOLD.

Here's the practical way of testing 18 karat up to 22 karat fineness in gold

Pour nitric acid on the gold deposit then pour cigarette aches once then pour again nitric acid and wash the test stone in water, see if there is any gold deposit left on it, see if the color is reddish brown its 18kt., yellowish golden its 22 kt., and if the gold deposit is completely dissolved, the karat fineness is lower than 18kt. 

Pure Gold - is gold inside and outside of the metal.

Gold Filled (G.F.) -  is the process of sweating gold all over the surface of a base metal or rolling a base metal on a thin sheet of gold with a different finenes in gold.

Gold Plated (G.P.) - is the process os washing a base metal with the different fineness in gold solution by means of ELECTRO PLATING MACHINE

GOLD is pure and  fine, it is naturally yellow in color and it is the most malleable and ductile of all metals. Pure Gold is alloyed with other metals to make it harder and more resistant to wear, to reduce it's cost and to obtain different color. It is known by Karat / Carat.


KARAT indicates purity or how much of the metal in a piece of jewelry is gold.

24K (.999) pure gold (too soft to use in jewelry)
22K (.916) very soft for use of jewelry / bend out of shape
21K (.875) very fine jewelry
18K (.750) fine jewelry
14K (.585) use in traditional jewelry / hard and metal maintain it's original look
12K (.500) color is not attractive
10K (.417) average or legal karat to be called GOLD

About Pawnshop

Pawnshop

A business that lends money with interest rate in exchange for collateral such as Jewelry or anything else that is judged to have a resale value. Pawnshops play an important role in many communities by providing people with an easy, fast way to borrow small amounts of money.




Pawnbroker is an individual or business (Pawnshop) that offers secured loans to people, with items of personal property used as collateral. The word pawn is derived from the Latin pignus, for pledge, and the items having been pawned to the broker are themselves called pledges or pawns, or simply the collateral.

If an item is pawned for a loan, within a certain period of time the pawner may purchase it back for the amount of the loan plus some agreed amount for interest. The amount of time, and rate of interest, is governed by law or by the pawnbroker's policies. If the loan is not paid within the time period, the pawned item will be offered for sale by the pawnbroker/secondhand dealer. The pawnbroker/secondhand dealer also sells items that have been sold outright by customers to the pawnbroker or secondhand dealer.

Pawnbroker - Any person engaged in the business of lending money on the security of pledged goods and who may also purchase for resale from dealers.
Pawnshop - The location at which, or premises in which, a pawnbroker regularly conducts business
