I went shopping last night now I need some help please

Sounds like that would make my little vase worth less, not more  oh well I still like it.
I have a small white onyx cup and saucer, not a mark on them at all, but surprisingly heavy for the size.  With no markings is there any point in sending pictures?  Your opinion please.

Yes !!  Send pics and one close up !!

My white onyx cup and saucer.  Saucer is 4.25" in diameter.  Cup 2.5" in diameter and 1.5" tall.  I did do some research and it is my belief it is white onyx.  Interestingly enough I found two other identical cups and saucers on ebay.  One says it is a Chinese hand carved cup and saucer in some kind of hard stone, early 1900's or even later. $50.USD   The other was hand carved white jade. $65.USD 
Neither of the cups or saucers had any marking on the bottoms.  As you can tell by measurements these are very small.  I think too small to be demitasse but I could be wrong about that.
Both those guys on ebay had really high approval ratings, 98 and 100% respectively.  I am baffled how one could say Chinese hand carved without markings but who am I to argue.  I will leave that to the experts on this forum.
Thanks

Certainly looks like similar striations in these !!

Here are better pictures of cups. Yes they do look similar.

What you may have is an espresso cup !! Larger than demitasse but smaller than coffee cup !!

[debc]

And I thought it was too big for demitasse.  So, what do you think of the hand carved in China theory?  It is a cute little cup and saucer but more of a dust collector I am afraid.

[mart]

I think its very nice !!  So translucent you can see through it !! Are you going to sell it ?? Looks better than the clunky things I saw on ebay !!

I like it too!  Very unique!  That stone would normally be heavy...but with it being thinned so much to be translucent is it regular cup weight or heavy for it's size?

[mart]

I would not have a clue as  to where it was made !!  China is as good a place as any !!  Saw some heavy stuff from Pakistan but this is much finer work !!

[debc]

It is most definitely heavy for its size.  I would part with it that's for sure, there is no sentimental value for me.   I guess it is hard to come up with a value, and description without knowing anything for sure, that is why I was surprised at the ebay ad for the same thing, hand carved in China, early 1900's or even earlier his ad stated.  Sounds a bit bogus to me.
Oh well.  The tortoise shell collection has all my attention now.  Interesting,amazing yet somewhat disturbing as well but I anxiously check the feed a few times a day

I have seen these in the past.  Search Antique Carved Onyx Coffee Cups, or Tea Set or Espresso Cups.  Now back in the past the buzz word was alabaster.  So you might try it that was as well.

Here is a set (with brass) that sold for a "Best Offer" so we don't know the ending price

Those cups with the brass are beautiful, I found the selling price $299 USD as far as I can tell.
The cup and saucer I have, while quite translucent are also quite heavy for the size. 
Thanks so much for all the comments and help.
So greatly appreciated.  Have a great day
