Looking for help ID-ing this little pendant I polished up!

[magpie_mulberry]

Hello there!  I'm relatively new to online reselling, although I've appreciated and hunted treasures in-person for the 4 decades I've been alive LOL!

That said, I'm trying to see if anyone can help me ID this pendant I found in a ziplock bag at a recent estate sale. It was super dingy looking, but not really discolored - just generally dirty. I spent a buck on it, and brought it home. 

A soak in lukewarm water and hydrogen peroxide, and then using a silver cloth brought out major sparkle. I used a nano bristle toothbrush to clean the bail and setting, and I noticed a stamp that looks to say "22" under my loupe. No "k" but just "22." Maybe SS?

Under 60x the stone has a lot of intersecting hatch striations, sort of like very loose cheesecloth. (I'm not very far along with my gem knowledge identification yet.)

The only part that shows any magnetic pull is the spring ring, and I know that is common with stainless steel internal springs, etc. Any help and ID is appreciated!

Do you have a picture?

Like poster @auntiekittys states we need some pictures. Tap the square box on right side ^^^^ and take photos of mark and whole entire item. If you have trouble come back.

No idea why, but Ebay is not allowing me to upload photos. I tried to delete the post after realizing I can't share photos, and I received a message stating that I was out of time to edit my post. Oh well. I guess I don't pay enough in fees or something to fully participate?

What are the letters or numbers on the side of the bail?

I suspect the gem is a doublet...that is a very thin layer of garnet (or ruby or sapphire), cemented on to a glass base.  This is how they made some simulated stones many years ago.  See if the cross-hatch inclusions are all on the top part of the gem versus all the way through.  Then you might find gas bubbles, swirl marks, rounded facet junctions, and/or an "orange peel effect" on the lower part.  You may also see a "separation plane" on the top surface of the gem that looks like a little line running around the top of the gem; that marks where the gem portion meets glass.

If the cross-hatch inclusions go all the way through the gem, top to bottom, and there is no indication of an assembled stone, then you most likely have a garnet; possibly rhodolite.
