New to forums: 14k ADL and mystery ring

[Ringguy1986]

Good morning everyone. Please help me learn about theae two rings I received this week in a lot. First one looks to be diamonds and is stamped 14K ADL. I am not sure about the smaller ring or what the stones could be. It is stamped 14k and nothing more. Just curious about age, materials?

Hi, unfortunately no one can tell from a photo if the clear gems are diamonds, white sapphire, white topaz or a diamond look a like (CZ or Mossinite).
The first ring, looks to be good craftsmanship so they are likely to be diamonds. The ADL is probably the maker or retailer but I can’t tell you who that might be.
The other ring, I can’t tell the colour of the gems but they look black, probably onyx or if dark blue, then sapphire.
Probably dated from the 80s / 90s. Princess cut gems were popular then.
