I bought a ring advertised as platinum. It was marked PL. I went to 3 different jewelry shops, 2 said 18k white gold, one said platinum. Whom should I trust? I am trying to find someone with xrf but no luck.
I remember this conversation. Do you have a pic of the ring? I would try a few more. But do not give them any info from yourself and see? Maybe! Does it say 18k
It's been a long time. but normally PL, PT or PLAT meant Platinum. But take it to a high end jewelry store or high end coin shop, they'll know for sure.
Call them and ask. But Zales and Jared are typical consumer level shops. But where I live there are some high end coin and jewelry shops ... if you walk in them you immediately know the difference.
The ring shank looks yellow compared to the head. If it is off white or yellow it is not platinum, platinum is a white metal and will not tarnish. Also if the diamond is real the chances of it being plated is greatly diminished. It is possibly a gold ring with a platinum head. What is the exact markings in the ring? Any reputable jewelry store or pawnshop should be able to do an acid test to determine the metal(s) involved.
Also the most common markings for platinum are "Platinum", "Pt", "Plat", "950 Pt." or "900 Pt." If there is a karat marking ("ie. 14k) and "Pt" together that would indicate a platinum head.
It's hard to see but I think stamp says 18K PL. Score is now PT 5 - AU 2. Went to 7 shops. Last one said it's PT with yellow gold in the front.
If you ever get to New York City the "Diamond District" ( 47TH St. bet. 5th & 6th Ave.) is loaded with jewelry shops.
I would venture to guess that it is platinum with yellow gold accents. Have you had the stone examined? If it's a real diamond, then it is not a plated ring. What would be the point in that? Generally, the values of metal and stone correlate. I don't think you'll find too many 18k gold solitaires with a CZ. For gold plated jewelry (white, rose or yellow), I don't recall an L being in the stamp. Maybe because it will confuse it with platinum. I've seen just karat stamps (solid), GP (gold plate), GF (gold filled) and RGP (rolled gold plate).
