called nitro-hydrochloric acid. The mixture is formed by mixing
concentrated nitric acid and concentrated hydrochloric acid. It was
named so because it can dissolve the so-called "royal metals," or
"noble metals", gold, Silver and platinum. However, tantalum, iridium,
osmium, titanium and a few other metals are also capable of
Lock in - as in lock in your price (agreement to buy or sell

24K gold - is 99.9% pure gold or higher.
22k gold - contains 22 parts gold and 2 parts of one or more
additional metals, making it 91.67% gold.
18K gold - contains 18 parts gold and 6 parts of one or more
additional metals, making it 75% gold.
14K gold - contains 14 parts gold and 10 parts of one or more

or more additional metals, making it 50% gold.
10K gold - contains 10 parts gold and 14 parts of one or more

Dental Gold - 12K to 18k (You will want Gold Test Needles to
narrow it down.)
European gold jewelry is marked with numbers that indicate
their percentage of gold, 18K gold - is marked 750 to indicate
75% gold 14K gold - is marked 585 for 58.5% K gold - is marked 417 for
Plumb Gold - Gold that meets the stamped karat content. An
assurance that gold is not under karated which was allowed before 1976.
A stamp in a ring such as 14KP means the item is plumb (the P does not
stand for plated), having the full 14 parts gold and 10 parts
alloy. An item marked 14K in the USA can be ½ karat short of
14/24 gold (58.33% ). Same is true of 10k through
24K. KEEP THIS IN MIND WHEN CALCULATING BUY AND SELL
WHITE GOLD: An alloy of gold that has nickel as the
main agent for creating the silvery color. Needs to be rhodium plated
on a regular basis to maintain a bright white color or it will turn
slightly yellowish. Not found in nature.
YELLOW GOLD: The natural color of pure gold is a deep
yellow. As the alloys increase the color of the gold begins to pale.
Therefore, 18K yellow gold has a deeper color than 14K or 10K yellow
ROSE GOLD: Gold has been alloyed with copper and silver
producing a pink tint. Tends to tarnish more quickly than other gold
GOLD PLATE: A base metal that is electroplated with gold.
Also known as gold flash, gold finish, gold tone or gold dipped.
GOLD FILLED: A layer of gold bonded to a base metal. The
weight of gold must be 1/20th of the total weight or more and must be
10K or better. Wears better than gold plated items because there is
much more gold.
BULLION: Any refined precious metal, such as gold, silver,
platinum, and palladium, which is in a state or condition where its
value depends primarily upon its precious metal content and not its
BASE METAL: Any non-porous metal which is often electroplated
or bonded with gold.
VERMEIL: Gold plated over silver.
Sterling Silver: is of 92.5% silver and 7.5% other metal
Mexican silver: generally contains less than 90% fine silver.
Troy Ounce - is the only ounce used in the pricing of
precious metals, gold, platinum, and silver .The troy ounce (ozt) is
480 grains, a grain is exactly 64.79891 mg; hence one troy ounce is
exactly 31.1034768 g, rounded to 31.1g. The gram is the weight most
used in trading precious metals.
Avoirdupois Ounce - (oz) sometime referred to as a Commodity
ounce is equal to 437.5 grains (28.35 grams). 3.63 grams less than the
Troy ounce (ozt). Avoirdupois ounce should never be used in
pricing precious metals (beware some people don’t know this and weigh
their gold using a Commodity ounce scale (letter scale) and advertise
it for sale.
Penny Weight - a unit of 24 grains or 1/20 of an Troy
ounce (1.555 grams). Abbreviation: dwt, pwt . A term mostly used (in
this writers opinion) to confuse the less knowledgeable buyer or
Carat - (abbreviation ct or kt) is a measure of the purity of
gold alloys. In the United States and Canada, the spelling karat is
used. The carat as a unit of mass equal to 200 mg (0.007055 oz), and it
is used for measuring gemstones and pearls. Sometimes known as the
metric carat which is divisible into one hundred points of two
milligrams each. Here are several ways to express 1 carat as in diamond
carat: 1 ct. = 1/5 gram, 100 points, 200
milligrams or 4 grainier. (not often used in a retail environment).
POINT - is 1/100 of a carat. 0.75 carats is equal to 75
Platinum - a shiny white silvery metal used to make fine
jewelry. It resistance to wear , tarnish, excellent resistance to
corrosion and high temperatures and has stable electrical properties.
It can be corroded by halogens, cyanide's, sulfur, and caustic alkali.
Platinum is insoluble in hydrochloric or nitric acid, but dissolves in
aqua regia to form chloroplatinic acid, H2PtCl6.
The Platinum Group of Metals:
Six related metals belong to the Platinum Group of Metals PGM:
Platinum, Rhodium, Iridium, Palladium, Ruthenium and Osmium.
Jewelry can contain different percentages of pure platinum. The US
Federal Trade Commission (FTC) publishes guidelines for acceptable
marking standards for platinum jewelry sold in the US.
Platinum content is usually expressed as the amount of pure platinum
the jewelry contains in parts per thousand. Think about it like this...
you mix up a huge bucket of SAND and GRAVEL that contains 1,000
ounces--900 hundred of the ounces are SAND and 100 are GRAVEL. That
makes the SAND 900 parts per thousand of your mix. Another way to
express this is to say that SAND makes up ninety percent of the
mix--900 divided by 1000.
Jewelry that contains at
least 950 parts per thousand of pure platinum may be marked or
described as "Platinum"
Jewelry that contains 850, 900 or 950 parts per thousand of pure
platinum may be marked "Plat" or "Pt" if a number is used in front of
the term to disclose the amount of pure platinum in the mix, such as
"850 Plat" or "850 Pt", or
"950 Plat" or "950 Pt"
Jewelry that contains at
least 950 parts per thousand of platinum group metals, with at least
500 parts per thousand of the total pure platinum, may be marked as
platinum as long as the numbers of each metal are disclosed. For
"600 Pt. 350 Ir." or 600
Plat. 350 Irid." for 600 parts pure platinum and 350 parts iridium
"550Pt. 350Pd. 50Ir." or
"550Plat. 350Pall. 50Irid." for 550 parts pure platinum, 350 parts
palladium and 50 parts iridium
The FTC is currently considering a request to allow manufacturers to
mark jewelry as platinum even if it contains metals that are not part
of the platinum group.
Platinum test acid cannot confirm the percentage of Platinum
there is in the test item.
