This simple gold ring has no etching or mark of any sort.  It’s pretty soft and pliable tho, much like normal gold; so one could be added easily enough.  The magic of the ring is a bit peculiar; when worn it allows you to see in the dark.  It does this in a peculiar way; random objects in the scene will appear to be on fire, and the light of the fire cast allows you too see in the dark.  The fire(s) seen have a very realistic look to them,complete with smoke and crackling noise, but is pure illusion; and only to the wearer of the ring.  It has a range of about 500′, so quite a few things may appear to be burning in the scene in order to provide enough illumination to see.
