The "14K" indicates that the gold content is 14 karat - or about 58% gold with the remaining 42% comprised of other metals. The CC, in this case, is more than likely a maker's mark, or a craftsman's "signature."
It's probably someones initials.
925 on a ring indicates that the ring is made of sterling silver, which is an alloy containing 92.5% silver and 7.5% other metals, such as copper. "CC" may stand for cubic zirconia, a synthetic gemstone often used as a diamond substitute in jewelry.
for a 10 karat wedding band size 12.5, i think it is maybe one gram or maybe 1.5 grams. the diameter of the ring i have is 22mm giving a circumference of close to 70mm. The thickness is 1 mm and the width is 3 mm. gold has a density of 19.3 grams per cc. my ring is about a fifth of a cc. if it was 24 karats that gives close to 4 grams of gold. my ring is only 10 karats
A quick way would be to see how much water it would displace. That would give you its volume. Weigh the ring and divide that by the volume of water the ring displaces (because the ring displaces a volume of water equal to its own volume). Use or convert to grams and milliliters, which are equal to cubic centimeters (or cc's). By dividing the ring's weight (its mass) by its volume, and then getting the answer in grams per one cc, you can compare your results with the density of pure gold. The density of pure gold is about 19.8 grams per cc, and with that information, you can make an educated guess as to whether or not the ring is pure gold.
88 in3 * 2.543 cm3/in3 ≈ 88 in3 * 16.387 cm3/in3 ≈ 1442 cm3
I also have a ring with cc in it. I have done a ton of research and believe the cc is Coronado Trading Company out of New Mexico. As near as I can tell they got in financial trouble around 1980 and are out of business. The 18 is probably the carat of gold used. As far as the fb goes I have no idea but a few minutes on the internet might give you the answer.
1442.06cc
The symbol "cc" inside a ring typically stands for "cubic centimeters," which is a unit of measurement used to denote engine displacement or the size of an engine. This measurement represents the total volume of all the cylinders within an engine.
1988 "the cc stand for 88"
1450
based on other answers to gold stamping i believe it would be a makers sign. if it has numbers and a k (i.e 123k) it would be how pure the gold is in carrots. (lol 123 carrot would be nice to have). if gold is a new purchase check with seller as may mean something to store or if it is a manufactured piece could be a company code
