The stamp 800 on gold jewelry likely means that the piece is old and not from the United States. The 800 denotes the amount of gold in the piece.
It's almost certainly the item's "fineness". For most jewelry the gold's purity is measured in units of 1000, often but not always represented as a decimal, with 1.000 being pure gold. Thus 800 (or 0.800 or .800) would mean gold that's 80% pure, with the remaining 20% being other metals added to increase the alloy's hardness.
It depends solely on the piece- 800 could be 800/1000 silver or 800/1000 gold- If the piece is silver, it's likely an older European piece.. If the piece is gold it's likely French 19k gold (EXTREMELY uncommon, but still can be found today.)
Gold jewelry in Portugual must by law be 19.2 karat pure, there fore the marking of 800 translates to 80% gold, or 19.2 parts out of 24 (24 parts being 24 karat gold, 100% pure). A lot of European gold jewelry is marked 750, which ranslates to 75% gold content, or 18K, 18 out of 24 parts gold. Gold in the US is typically 14K or 58.5% gold, which is represented by the mark 585, 417 is 10K, 41.7% gold. Hope this helps.
An 800 stamp on a cameo indicates that the piece is made of silver that is 80% pure, which is equivalent to 800 parts per thousand. This mark reflects the quality of the silver used in the jewelry, distinguishing it from sterling silver, which is 92.5% pure. Cameos with this marking are often associated with European craftsmanship, particularly from Italy and Germany, where such standards are commonly used.
Gold MarksIn gold jewelry, a stamping of 24 kt or 999 means that it is 100 percent pure gold, 18 kt or 750 means that is 75 percent pure gold, 14 kt or 585 is 58.3 percent pure gold, and 10 kt or 417 is 41.6 percent pure gold.Silver MarksA stamping of 925 in silver jewelry means that it is sterling silver and contains 92.5 percent pure silver, with the rest being other metals such as copper. In European jewelry, it is also possible to see hallmarks such as .800 or .813 which also indicate the percentage of pure silver in the piece.See the related links below for more information.

Well, honey, let me tell you straight - jewelry stamped with 823 ain't real. That number doesn't correspond to any known precious metal purity. So, if you're looking for the real deal, you better keep on searching, darling.
If im correct it means that it is an 800 gold Karrot ring.im not 100% certain though. You should go to a jewler near your city/town and find out.
Platinum is commonly marked with 950 or 850 so check your jewelry: If a piece of jewelry contains at least 950 parts per thousand of pure platinum, it can be marked simply platinum. If an Item have at least 850 parts per thousand of pure platinum, it can be marked with the amount of pure platinum and the word platinum or an abbreviation (i.e.: 850 platinum, 850 Plat or 850 Pt.). Silver is commonly marked with 925 for sterling silver and 999 for pure silver. There are other lesser grade marks for silver but they are uncommon. There are some low grade silver marks out there though. I happen to have a silver belt stamped 800 silver. Some jewelers stamp the percentage of gold rather than the typical 10k, 14k, 18k, 22k, 24k. If the piece is real gold it is easy to convert the percentage to the k that we are used to seeing. The computation is as follows: 24 (for 24K) x 0.417= 10 (for 10k), 24k x 0.583 =14k, a common stamp would be 583 or 585 24k x 0.750 = 18k, a common stamp would be 750 24k x 0.917 = 22k, a common stamp would be 917 or 918 24k x 0.999 = 24k a common stamp would be 999 Rarely do you see a number stamp for 10k since 10k gold is not as common in other countries. Conversly you can also easily calculate the percentage of gold in your jewelry by using the karat: 10k / 24k = 0.417 x 100 = 41.7% gold in 10k, 14k / 24k = 0.583 x 100 = 58.3% gold in 14k 18k / 24k = 0.750 x 100 = 75% gold in 18k 22k / 24k = 0.917 x 100 = 91.7 % gold in 22k 24k / 24k = 1 x 100 = 100% gold in 24k
I think it was in 1906 Gold and Silver began stamping, as required. Later the law was amended to add Gold and Silver would now have to show its content, i.e.: 10kt, 14kt, 18kt, etc. or .925, .800, etc.
The value of 800 pounds of gold would depend on the current market price of gold. As of [current date], the price of gold is approximately [current price per ounce]. To determine the value of 800 pounds of gold, you would first convert pounds to ounces (1 pound = 16 ounces) and then multiply the total ounces by the current price per ounce of gold.
800 parts of silver per 1000, or 80% silver, 20% other metal. Sterling silver is 925/1000 or 92.5% silver. 800 silver is not sterling quality. .888 silver is "coin silver" as opposed to "stirling silver." It has more nickel in it to make it harder for use in coins. Coin silver must be 900 silver, by law.
