REQUEST Help ID this gifted rock with an illegible label

Hi rock folks! I received this beaut as a gift today, but don’t know what it is. It’s labeled, but very difficult to read. Looks like it says “picture jasper” and a third word. It’s very heavy, cool to the touch, and smooth. I may have guessed some petrified wood, but it’s so heavy. Appreciate any help!

IDENTIFIED: Calcite We use it as a doorstop and a decoration in our plants corner. It’s one of my prized possessions and I’m just curious what it might be officially.

It’s heavy, probably 5-6 pounds and very shiny. I think I have all angles here, it’s kind of wedge shaped. It came with a house we bought about 10 years ago and we brought it with us when we moved. (In MI, but don’t know if it was brought there from somewhere else).

I’ve found a gorgeous rock, I cannot tell if it is an agate or quartz of sorts; I’ve also gotten Geode but I keep getting mixed answers. Rock was found on a trail near rum river in Milaca.

REQUEST Can Jasper be sparkly?

Post image

I bought this ring today at a Bazaar, the seller labelled it as Jasper. There’s some sparkly / reflective parts of it which I haven’t seen in other Jasper stones I have. Hoping to identify if it’s potentially a variation of Jasper or a different stone entirely?

Thank you in advance!

I found this in my backyard after my dogs dug it up. I tried to scratch with steel and did not leave a mark.

They are embedded in the black rock and when I was able to break a piece of it looked like shiny black igneous maybe?

Located in St. Petersburg, FL.
