If there is a + and - at the ends of the arrow as well, it's a DC supply pictogram (8volt)

the 8 is the size
Have a ring RJ 8 marked inside. The 8 refers to ring size. Am searching RJ myself.
The "10k RJ" etched in a ring would usually refer to the fact that it is 10-karat gold, with "RJ" probably being the maker's or manufacturer's mark. 10-karat gold contains an alloy of 41.7% pure gold, mixed with other metals for strength.
Korea = Country of Origin or what country the ring is from. 8 = Ring Size
From what I understand some jewelers stamped in the ring size!
If the ring is gold, it means it is either 8 or 9 karat gold.
The NV in your ring means that your ring was made from the Nevada Silver Mines which in turns mean that your ring is Sterling Silver. The next letters you are referring to is au which is the periodic symbol for Gold meaning thet your ring is in fact real gold.
In archery, if an arrow lands between the red and yellow rings on the target, it typically scores 8 points. The red ring generally scores 5 or 6 points, while the yellow ring scores 9 or 10 points, depending on the specific target used. Therefore, if an arrow is positioned between these two rings, it is usually assigned a score of 8.
I have NV and 8 stamped inside my 3 joined rings and they're bronze, silver and gold in colour, someone told me it stand for either Nevada Silver or the ring size for countries such as Australia.
The marking "925" inside a ring indicates that the ring is made of sterling silver, which is an alloy containing 92.5% silver and 7.5% other metals. The marking "8nv" is not a standard hallmark and could potentially be a manufacturer's mark or a custom engraving. It's always best to consult with a jeweler or appraiser for a more accurate assessment of the specific markings on your ring.
