Are these items worth anything?

Are any of these worth anything? I do not know what they are. The both rings are silver, and the one on top of the orange rock thing has a shiny diamond looking very small thing in it. Beautiful items, but are they worth more than 5€? And a important question: what are those stones?

The only one I know is the top one (white stone with orange crystals). It is called "agate" and comes in many colours. I believe these crystals form in caves and the colour depends on the minerals in the crystal...iron, silica, calcium, etc. I am by know means an expert (come to think of it, not even a novice).

People do collect them.

It looks like you have some quartz in there. But I can't help on the exact names of stones. The beetIe looks interesting, and if you haven't already done so, find out if those rings are sterling using a magnifier to look for any stamping on the ring. One might say 92.5, and then you know what you have. But even if those coins are sterling, but they probably would not be worth more than $5 dollars. I would suggest looking for a local dealer and asking them what they are-first off. Don't sell until you exactly know what you have. There are many unscrupulous dealers out there-so be careful. The key is to know what you have...or you could just keep them instead.

I think the nicest piece you have there is that beetle-it may have been made with some lapis lazuli, which is one of my favorite stones. William Butler Yeats wrote a poem by the same name, and it is worth the reading. I think the whole group is definitely worth 5 pounds.

​So there is agate, some kind of a white crystal thing,
Larger ring has about 92% silver. The smaller is so used that I cannot see the amount, but something below 92% though. The thing in it is probably a glass made diamond or a synthetic diamond but it is very small.

The rocks. I did not find anything on the gray one, the amber looking one (is it amber? probably no?) or the black one with purple small spots. Although I searched and found that it looks like something called corundum.

The bug is probably not worth anything but its beautiful, Ill keep it. I actually had no intention to sell anything, but just asking what they are.
The crystal is, I guess, some kind of a crystal, not worth really much but beautiful still.

Questions without answers:
What is the grey stone?
What is the amber-looking stone?
What is the blackpurple stone?
Is the orange one corundum?
What is the thing in the small ring?

Silver rings have no resale, just silver value.
You can get polished stones in big bags at the home decorating store.
The cristal is quartz https://www.google.com/search?q=orange+quartz&client=safari&hl=en-us&prmd=sinv&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjFua7GqqHYAhVV72MKHaeZDJAQ_AUIEigC&biw=320&bih=454

I guess we still have three questions, others I have already found answers during the night.

What is the grey stone?
The orange? (Looks exactly like amber but not see-through)
The grey one?

Those are the polished stones I was referring to, not valuable, just nice to look at.
You can also buy these for kids rock collections, but they are just quartzite that have been tumbled and polished, they do this on an industrial scale.
I put a big bag full like those in my creek for my kids to find when they are playing in the water. If I had those three, they would follow the others.
