Lot Costume Rings Vintage Estate

Description

This is a lot of 25 vintage/estate costume jewelry rings in various sizes and in varying condition, for use, repurposing or resale.  I have tried to read the maker and other marks from inside the rings, but as some marks are not legible and I am not a jeweler,
I cannot be sure of the exact materials used in each ring
.  In the descriptions below, I use the term 'stone' in a generic way to include glass, cubic zirconia, or natural materials like gemstones. So 'stone' doesn't necessarily mean a gemstone. If you have questions or want more photos of anything in particular, please ask in advance, but I am selling these AS IS.  NOTE:  The black velvet ring displays shown in the photos are NOT included.
The rings will ship in individual ziploc bags marked with the size and the identifying letter shown in the photo.
I have measured each ring, but there could be minor size discrepancies from what I've measured.  A brief description of each follows, but I am unable to upload detailed photos of each ring, so if there are some rings that you want more photos for, please let me know and I will be glad to get you more photos.
A. Size 5.  This appears to be some type of wood, in a mottled dark rose shade.  It has no maker marks.
B. Size 5.5.  This is a silver tone ring with inlaid stone or enamel (I can't tell which). There are no makers marks, but there is some visible wear to the silver metal interior.
C. Size 5.75.  This is a silver tone ring with a darker metal inlaid in the middle of the top.  On the inside it reads '12KGF Sterling , and the letter 'K' also appears.  There is damage to the finish on the inside in one section.
D. Size 6.  This is a silver tone ring with three stones. The center stone is a yellow/lime green shade and the two smaller stones are white/clear.  There are marks on the inside but they are difficult to read.
E. Size 6.  This is a silver tone ring with three stones.  The center is a blue/aquamarine shade and the two smaller stones on either side are white/clear. There are marks on the inside but they are difficult to read.
F. Size 8.  This is a beautiful silvertone and malachite ring.  The inside reads '925' and three letters that I cannot read. It was purchased new at Macy's in the early 2000's.
G. Size 8.  This is a ring marked '925' on the inside, with stones or glass accents in a muted lavender/blue shade.  It is beautiful and unique.
H. Size 8.  This is a silver tone metal ring in an art deco type design, with a rectangular stone that appears to be glass.  There are stones missing on each side, as well as some wear to the metal on the outside of the ring and near the large stone.  There are marks on the inside, including what looks like a patent number.  The stone/glass cabochon has some visible marks.
I. Size 8.   This is an unmarked solitaire ring in silver metal with a white unidentified stone.  It has not been tested but does not appear to be a diamond.
J. Size 6.5. Silvertone metal ring with cubic zirconia or rhinestones.  There is a mark on the inside but I cannot read it.  There is one stone missing.
K.  Size 6.75.  This is a silvertone ring with a lime green checkerboard stone.  There are two marks on the inside. I believe one reads '925' but I cannot read the other mark. It could be silver plated, but it doesn't react to a magnet so I am not sure.
L. Size 6.75.  This is a silvertone ring with a purple center stone in an amethyst purple shade, and two red stones on either side.  There is a mark on the inside that reads '925' and another mark but I cannot tell what it says.

N. Size 7.  This is a silver tone metal ring with a teal/aquamarine colored center stone or glass cabachon.  There also appears to be a tiny chip of some stone or a rhinestone on each side.  The ring reacts to a magnet, and there are no marks on the inside.
O. Size 7.  This is a gold metal ring with a center stone of a deep shade of red, surrounded by what appear to be rhinestones (glued in).  I cannot tell what the metal is, or what the stones are.  It doesn't react to a magnet but the color of the metal is a deep shade of gold. There is a mark on the inside but I cannot read it.
P. Size 7.  Goldtone ring with swirl accents in silver tone metal.  There is a mark on the inside that reads '14 KTGE' and there is another mark that I cannot read.
