FF commonly means "fracture filled" or "fissur filled," meaning there were cracks in the stone that were filled.
P means plumb, a term used to indicate a full 14 karat, rather than a 'some times almost'. minute differences but a better grade of 14k. FF is the maker.
It almost always means that the piece of jewelry is Gold Plated over a Silver piece of Jewelry I work in the jewelry business and the above answer is incorrect. 585 is the stamp for a peice that is 14K gold. If it is plated it will have additional letters such as GE for gold electroplate or GF for gold filled. If it is stamped 585 P that stands for plum and has been tested to be 14K solid gold.
Plumb.. TRUE GOLD
K.P.G. = Kilometers Per Gallon it means plumb gold
it means certified jewelry.. by the gold council..its safe to buy it.
I believe it stands for Copper base metal with a Heavy gold coating, i recently bought a piece of jewelry marked exactly that and could see where the gold was lifting ,acid tested it and it went crazy. not solid gold avoid at all costs.
6 t flip flops are needed ( to connected as in asynchronous counter), 1st t ff o/p freq will be same as i/p clk, 2nd t ff o/p freq will be half of i/p freq, and 3rd ones o/p freq is i/p freq divided by 4...... so the o/p freq of 6th ff will be i/p freq divided by 32.
PAT P stamped on the clasp of a piece of jewelry means patent pending. It simply means that the jewelry designer has a copyright on the design of the jewelry.
Hi... when you see P 10k or 10k P on a piece of jewelry, it means that the purity of the gold is guaranteed to be 10k or better. The "P" means PLUMB it is a higher purity of gold making it a better quality. "P" does not mean any kind of plating. Gold plating marks are as follows: GP, RGP, HGE, GF.
Many people believe that P and PL on gold indicates that it is plate. The P and PL are older terminology that was used to indicate exact or plumb Karat. A ring that is 13.5K can be listed as 14K gold but a ring that is 14KPl is exactly 14K gold or 58.33% gold. 14K and 14KPL are very fine quality of gold and 14K is one the most common gradings of gold sold today.
I have a white gold, antique ladies white topaz w/ 18K inside and on the other side C-P. I haven't found out anythiny yet.
tibok-tibok-tibok-tibok haha :P
It generally means "and following". It is used for example in citations and reference literature when the reference is to "page 15 and the following pages", then the annotation is ".... p 15 ff."
