In my mother's estate was an old (I think?) diamond ring with this
inscribed on the inside of the ring:  14K, o celi.   I am not
absolutely certain whether the "o" in the above description IS an "o"
or whether it is simply a symbol of some sort (perhaps a diamond
symbol??), but the rest of what is written above is accurate.   There
are then 3 figures over on the other side:   C 0 5.  Do you have any
idea (or can you find out) the
manufacturer of this ring and anything else about it or the maker?  I
am NOT looking for an appraisal (of course), but am simply interested
in its history & any other info there might be.   Thanks.
