From an Internet search, you can find data for simple alloys such as gold-silver and gold-copper. But because of multicomponent effects noted above, 9 carat gold has SG range 10.9-12.7, 18 carat yellow gold 15.2-15.9, 18 carat white gold 14.7-16.9, 22 carat 17.7-17.8, sterling silver 10.2-10.3.
The Specific Gravity Test is used to calculate the gold content of gold nuggets that contain a mixture of gold and other materials. In this example of the specific gravity test, we use gold mixed with quartz. Nugget weighed in air weighs 96 grams. Nugget suspended in water weighs 74.5 grams ...

Thus a .10 carat stone can be called either 10 points, or 1/10 of a carat. Small stones like .05, and .10ct are most often referred to by point designations. The spelling of karat with a "K" is a measure of the purity of a gold alloy, as opposed to stones. A one carat round diamond of average proportions is approximately 6.5mm in diameter.

its specific gravity. If it wasn't 19.3, the goldsmith was in BIIGGG trouble. Your problem is a little more complex because you need to know what percentage of Gold is in the alloy. However, the approach is the same. Measure the Specific Gravity. (There has been a recent thread on the subject, but I'll give you an equation to use.)
To explain that in other words, the specific gravity of gold is 19.3 which means the weight of gold is 19.3 times that of an equivalent volume of water (at 4 degrees C). If water weight is 1 gram per ml then Gold at an SG of 19.3 is 19.3 times as dense as water or 19.3 grams
The simplest way to test specific gravity is weigh the quartz gold specimen in "air" and multiply the weight by 1.9. Then weigh the quartz gold specimen fully submerged in "distilled water" and multiply that weight by 3.1. Minus the wet figure from the dry figure and you will get a fairly accurate specific gravity for that specimen!!

Calculate the specific gravity of the salt water. 2. Specific gravity of emerald [Be 3 Al 2 (SiO 3) 6 ... Knowing that one carat = .2 grams or 200 milligrams, calculate the mass of the unknown green stone (from Problem 2 above) in carats. ... The density of pure gold is 19.3g/cm3. What is the volume of 1 ounce of gold (A Troy ounce of gold ...
Gold alloys, such as products of 9, 14, 18 and 22 carat purity, will have slightly lower densities than a pure (24 carat) gold coin or bar due to the other materials being mixed with gold. A one ounce, 24ct gold coin, will be smaller than a one ounce, 22ct coin for example, because it is denser.
3) The mass densities of gold and copper are 19.3 gr/cm 3 and 8.9 gr/cm 3, respectively. A piece of gold necklace has a mass of 51.0 grams and a volume of 3.50 cm 3. Calculate (a) the mass percentage and (b) the karat of gold in the alloy assuming that the volume of the alloy is equal to the volume of copper plus the volume of gold.
While an acid test will do a lot of what we need, Specific Gravity (SG) can be used to identify just about any elemental metal and reveal gold filled or plated jewelry, as well as other imposters. If the word "Math" doesn't make you swoon, you can also determine weights and types of mounted gemstones (1+ carat) and two part alloys where one ...
The diamond (with a specific gravity of 3.52,) will weigh 1 carat. A sapphire (specific gravity 4,) will weigh 1.14 carats. The opal (specific gravity 2.15) will only weigh .61 carats. There are subtle variations to this list. For example, some list a .25 carat diamond as measuring 4.1 mm.
Specific gravity is the ratio of the weight of a sample (in this case, your bar), to an equal volume of water. The density ratio of gold:water is 19.32:1. This represents a Specific Gravity of 19.32. If the specific gravity of your bar is only 1.06, then it is only 0.31 % of the density of gold.
Consider two balls of equal weight but of different specific gravity, for instance a 10 gram gold ball and a 10 gram silver ball. The gold ball has a sg of 19.3, while silver has a sg of 10.5. Because gold has a sg that is almost twice as much as silver, you can imagine that the 10 gram gold ball will be smaller than the 10 gram silver ball.
Divide 1,000 by this total‑the answer is the specific gravity of the alloy. Example. Find the specific gravity of 14K yellow gold having . 583 parts gold, 104 parts silver and 313 parts copper. First figure the reciprocals of the specific gravities. Fine Gold ‑ 1 divided by 19.32=.051759. Fine Silver ‑ …

the specific gravity method tells us whether gold is "about 20ct" or "about 22ct" but it's not quite accurate enough to measure to the nearest 1ct. THE FOLLOWING TESTS WERE CARRIED OUT ON A PURE (.999 / 24ct) BAR OF GOLD, which we know, from the chart above, should read 19.3.
We developed this particular version of our Universal Specific Gravity Kit primarily for the gem and jewelry trade, and in doing so, we downsized the components to be compatible with virtually any pocket/compact Carat scale, provided that: . The scale has a minimum capacity of 50 carats.; The scale has a tare (re-zeroing) function.; The scale's weighing platform is large enough to accommodate ...
Gold 0.583 x 10.180 = 5.935 Silver 0.120 x 5.525 = 0.663 Copper 0.297 x 4.719 = 1.402; As shown above, total result of each multiplication. The sum is the estimated density of the alloy. Note: Each different alloy's density will probably be somewhat different. Specific Gravity, Melting Point, and Density of Various Metals and Alloys
It follows from the above table that: A cubic centimetre of gold will weigh 19.3 grams. A cubic metre of gold will weigh 19.3 tonnes. A cubic inch of gold will weigh 10.13 troy ounces = 11.06 avoirdupois (ordinary) ounces. A cubic foot of gold will weigh 1188.6 pounds (avoirdupois).
The Specific Gravity of Gold is 19.3. Therefore 19.3 grams occupy 1 cubic centimeter. 1 Troy ounce is 31.1 grams. So, to get the volume of 1 Troy Oz., we …
How to Calculate the Specific Gravity of a Coin  [ENG] Manual Why? To Know the specific gravity of a coin it is useful for the determination of its gold or silver content, this is an useful information to discover some fakes or to study the composition of certain coins.
with a specific gravity of 10. let's say that your sample weighs 1 gram and takes up 1/2 a cubic centimeter or 1/2 a millileter (hence giving it a specific gravity of 2 as 1/(1/2) =2). then, your equation to solve becomes 10=x/ (1/2) where 10 is the specific gravity of …
