Quarts with pink centre

[MagicMan86]

I bought this from a thrift store, I assume it's Quartz, but cannot find any other pictures online of quartz with such solid, localized and vivid pink in it, was wondering what this would be worth?

Your stone is a sawed-open piece of a naturally-filled-in quartz geode, which some people call a Thunder Egg. The center of yours is filled with banded agate.

I do not recall ever seeing agate which has the color of Conch-Throat Pink. There may be a trace mineral which can make SiO2 take on that particular version of seashell-pink color, but I do not know what. Perhaps the agate is colored by Pink Bismuth.

Or, somebody dyed or irradiated it.

I think it was treated in someway to enhance that color in the center.

Thanks for all the information, I do appreciate it, but I know it's worth more than I paid for it, that was the sole reason I bought it, to sell it on, but no idea what kind of price to be asking for it, anyone have any idea what geods like this sell for?

For NON-MANUFACTURED "Collectible" items like this, where there are no two alike, the dollar-value is almost entirely dependent on finding somebody who likes it enough to spend money on it. You can check prices for all sorts of geodes on the internet. Find one which looks very similar to yours, and is the same size (that's important). Search at internet sellers, or "Rock-Shop" websites, or Gems-&-Minerals shows. Then calculate the average among the various prices for duplicates of yours.
