Cabochon rings

[Abrhm]

These cabochons are all in gold except the carnelian on the right. My initial thoughts are, left to right...yellow jade(diamonds), green jade, greenish jade, lavender jade and carnelian. These I know are much more recent and maybe not even antique?
My challenge is separating old from newer and gain enough knowledge to know what I’m dealing with. I’m truly appreciative of all the insight! Ps: anyone know of a site like this for ancient beads?

You might get more responses if you hit ''Report Concern' at the bottom of your post and ask a mod/admin person to move it to the coloured stones forum.

In my opinion the silver carnelian ring could potentially be the oldest- the hand chasing on the mount is beautiful. The others appear quite modern in comparison, and as you say seem to be different variations of jadeite, likely dyed and impregnated. The hallmarks may be able to tell us more information, but unfortunately they can't be seen in the images.
