Agate Flower

ok it is like a cross sword with a cross over the top of it (it is as one pendant though)
in the middle there is an orange agate stone (round)
then near this on the cross handles there is a red and green and purple and blue stones (i think these are agates as well)(these are also round)
then inbetween each of the smaller round stones there just above it there are some round stones in mint green , purple ,brown and red (i think these are agates)(these are rectanglular)
the bail is above the red rectangle stone
i have been told this is a scottish agate pendant however i can't find any hallmarks

i also have a rolled gold heart locket
this has a flowering tree on the main part of the locket
then the edges have a swirled pattern
i have been told this is from the 1950's

i was wondering if anyone knew how much these are worth and if anyone has similar
