Those are some pretty pieces. I personally usually go for other colors though, bright and vibrantly colored. I was about to say not the weed though, but realized after clicking the thumbnail is was concentrate LOL awesome so there too man.
I just got a new piece at a local place called Sky Smokeshop, my first of this new collection. They didn't even card me (let's just say I don't look 18 at all, but I am because I'm on this forum right), and sold it to me for just $20 and I'm almost positive he took a $25 price tag off it. It's super chunky glass with a deep and wide bowl, and variants of rasta colored swirls. Some stripes are swirly and textured, some have glitter even. A little bit of color change too, that kind of glasswork typical on a high quality piece where clear glass covers the actual colored design, inside out? Sorry I'm pretty high & never been interested in pipes until I finally got one instead of a bong or bubbler.
