Antique Gold Jewelry Marking Expert Help Needed

[kalalilly]

Can anyone tell me more about this old ring? It belonged to my Grandmother. I'm estimating it's from ~1900-1925. I'm not sure if the two green stones are emeralds. I believe the four tiny clear stones are mine cut diamonds. I don't know what the center stone is.

It looks like rose gold but I don't know if it's 14k or 18k. What does the X mark on the inside of the band indicate?

Any advice you can offer is much appreciated.

The photos are too dark to see details.The  small stones don't appear to be square and would not be mine cut.The "X" looks like a pair of scissors,the ring shank appears to be die struck,There is nothing on the ring to determine age unless the makers mark can be identified.

I cropped out the extraneous background and sharpened & lightened the entire photo in order to see the stones more clearly.

I couldn't get the mark on the inside to come in any clearer.
