I was walking up the driveway today when I noticed the rocks in the front garden my sister "donated" to us when she sold her house.... and I was thinking that might be interesting to cut... so I snuck the smallest stone (about 5 ppounds) out to the shed and cut 2-3 slabs but I can't ID them... kind of a red/orange/pink with quartz, some green stuff (that's a technical term for those of you less educated in the ways of the Military!!) and what appears to be mica. I'll let you decide what it could be.... These 2 I back lit with my desk lamp Wet Photos to follow! I do know that; 1) it isn't native to Florida, no rock is!! 2) it is quarried up in Connecticut and trucked south as landscape rock, my sisters ex was one of the drivers for the trucking company. 3) it is of medium density, not overly heavy for its size like garnets or sapphires. Thanx in advance !!

well I's say you have some granite on your hands. Red is feldspar, green epidosite, quartz (clear) and mica (silver or black). My first cab was of similar material: forum.rocktumblinghobby.com/index.cgi?board=ccabs&action=display&thread=50017This has a lot of black mica, little bits of quartz and no epidosite to speak of, but a lot of it does. If you find some with good amounts of green, pink (or red) and clear you have a combination called Unakite.

I may have to sneak out another or go online for landscape rock.. some of it is cheaper by the pound than the slabs they are selling on ebay !! You just gotta be willing to work with boulders... 20 - 200 pound rocks which leaves dents in the ground when they fall off your wheelbarrow!!!

I know most of the bigger ones have more color than this one, but this one was smaller too so not missed as easily... Unakite huh???, I guess I have at least 2 boulders of it out front way cool Thanx John!!

To be clear, unakite is somewhat colloquial - meaning that one man's unakite is another man's [whatever] - "real" unakite is somewhat equal parts green, red (or pink) and white/clear.
What you have slabbed is probably too heavy on the feldspar to be technically called unakite, but there are a lot of folks who market stuff similar to yours AS unakite.
Unless I'm wrong about the base material - can you tell how it fractures? Granites "chunk" apart, where jaspers and agates have that sharp conchoidal fracture.
Assuming I am right and it is granite, unless there is a lot of Mica, it should still take a nice shine and unless is is fractured or mixed hardness it can tumble or cab nicely.
I've had mixed results, but I do throw a decent amount in some of my loads because when it works it is pretty.

Looks like a feldspar to me. Can have varying shades of pink to orange color. Should polish well but can have softer areas that pull out, especially if that is mica in there. I love the discoveries around the parking lots and yards! Fran
