I'm not sure if this is an Onyx stone because when the light shines on the stone it shows an abalone effect which most onyx stones do not, they are solid black, or can this be an Agate Stone?

This piece is Sterling, not gold.
But it's still important to me to call the stone what it is and I'm not sure, thought maybe someone might know
I know how to describe the stone but I wanted to know the name of the stone, like I mentioned it looks like an onyx but not when the light shines on it.

Toni - Try eBay's Jewelry Board. The gals are wonderful over there and very knowledgeable. They'd be happy to help.

Could it be hematite?

No, there is no ones reflection in the stone.
If you look at the 2nd picture you will see part of a red circle line along the edge, that red line makes a complete circle inside the stone (oval shape) and inside the red circle there are shades of greens and dark yellow that look like the way abalone stone looks.
This color change happens when you move the stone from side to side
Hematite is a silvery, lustrous opaque stone that resembles metal so I don't think that's what this stone is. Because this stone has no metal look to it.

otteropp thanks for the site, it's very interesting, I saved it. I read through the site and didn't find any info that describes my stone.
Carnelian is a reddish brown to orange gemstone.
Between cooking for Thanksgiving and doing research on this stone It's giving me a headache,
I've checked many sites and none describe this stone I have.
I'm not trying to find info on this stone because I think it has great value, what I need to know is what I'm selling, so I can describe it correctly. I don't think I can say onyx stone because I sell lots of vintage onyx jewelry and I know this stone is different.
CBlev65252 Thanks for the suggestion, maybe tonight I will try the jewelry board.

It looks like labradorite, though a dark specimen to be sure.

OMG, I see the VirginMary in the second image. Quick, sell it to Golden Palace!
Fluff, labradorite?? Seriously?? I have never seen labradorite reflect light in concentric circles before.
I do like this piece but my vote would be for agate.

It doesn't look like any agate I've seen. Speaking of Agate, maybe our Aussie friend will pop up with his opinion.

Thanks Fluff for that info, I did searches and I learned more then I knew about stone and Labradorite.
I check many sites checking Labradorite and none of the black Labradorite looked like mine,
All the Labradorite that I saw had flashes in the color stone that were always present, where mine is only present when moved and the light brings the change in the stone.
Labradorite (a variety of plagioclase feldspar) is a fairly abundant grayish mineral that has brilliant flashes of color (usually green, blue or red) after it is polished (called labradorescence). The crystals are transparent to translucent. There is a darker variety of labradorite (called "black moonstone" which has bluish inclusions. Labradorite is usually cut with a flat surface in order to highlight the flashes of color.
then I checked the agate
The difference is in the layering. Black onyx has large, clear areas with no layers or spots and is suitable for carving into uniform figures or cameos. Black agate has spots, zones, or thin, closely spaced layers that can be seen as slightly different in color or reflectivity.
A semiprecious variety of chalcedony quartz that is a used often in jewelry. When chalcedony is variegated with spots or figures, or arranged in differently colored layers, it is called agate;
I'm kinda leaning towards Black Agate.
But i'm not positive

It appears to be rainbow obsidian.
Definitely not labradorite.

wgonzales Thank you for this information.
I check out a few sites and it does come the closes to what I have. What I found out is below.
Rainbow obsidian is an incredible stone. Born in the fires of a volcano, lava sometimes cools without any crystal growth, creating a translucent dark volcanic glass called obsidian. Occasionally, patterns of gas bubbles remaining from the lava flow line up, creating a fantastic rainbow effect that constantly changes in the light. No two stones are ever alike.
Rainbow obsidian is a translucent glassy black most of the time, but flashes rainbow colors as it moves in the light. This particular stone has green and aqua curved stripes.
So I would think that this is what the stone is that I have.

I googled "Onyx" and found the following site - Onyx is the black variety of agate.
http://www.mineralszone.com/stones/onyx.html
Onyx
Onyx
The name comes from the Greek word onyx which means nail of a finger or claw. Legend says that one day while Venus was sleeping Eros/Cupid cut her fingernails and left the clippings scattered on the ground. Because no part of a heavenly body can die, the gods turned them into stone which later became known as onyx.
It is a member of the chalcedony family which also includes carnelian, agate, bloodstone, etc. Occuring naturally in a variety of colors, black onyx is polished to enhance appearance, a member of the quartz family.
Originally, almost all colors of chalcedony from white to dark brown and black were called onyx (SiO2 with impurities). Today when we think of onyx we often preface the word with black to distinguish it from other varieties of onyx that come in white, reddish brown, brown and banded. A variety of onyx that is reddish brown with white and lighter reddish bands is known as sardonyx.
Physical Properties of Onyx
Onyx is a form of chalcedony, part of the quartz group. Like the other stones in the chalcedony family, onyx has a smooth, waxy luster. Onyx can be found in a wide range of colors, often layered.
Specific Gravity : 2.58 - 2.64
Refractive Index : 1.55 - 1.54
Hardness : 6.5 - 7.0 on Moh's scale
Chemical Properties of Onyx
Formula : SiO2
Elements : Si and O
Uses of Onyx
Black Onyx is often used as a backdrop in jewelry, such as cameos. It is also used as cabochons and as a building material.
Enhancements of Onyx
Black and colored onyx is always dyed. Onyz is easily dyed, so beware of the more "unnatural" looking colors, such as bright blue, etc. Onyx with red and white bands is sometimes referred to as "Sardonyx". Onyx is the black variety of agate. However some parts are more or less translucent. This is why it is often heated to accentuate the intensity of its color.

At the back office of some jewelry stores,there are geminologists with those machines,they could help you with the piece.
If it is Mexican obsidian,there must be some on Ebay already.
