Just bought this from our wholesaler friend for $87. About 5" across, gray agate with a triangular amethyst 'window'. It's the perfect size for a crystal quartz stand I bought several years ago - actually, the stand costs more than the sphere did, LOL! I think they look good together.
Agate sphere with amethyst 'window'
Our seller is Kirby Seid, a great guy who mostly sells to high-end professionals. We met him through a 'friend of a friend', and to those who have a personal intro, we get a discounted price. He lives nearby us, and does a lot of metaphysical workshops.
His own crystal website is: http://www.seidcrystals.com/
He also partners in the website for the Light Labyrinth:
We have one of his first-generation LED lightstands. These are high-end, computer-programmed stands hand-crafted in walnut. The color LEDs cycle through shifting colors - extremely beautiful effect with larger crystals. This citrine prism is quite large, 7"t x 7"w (which we also bought from Kirby long ago), and here's a photo of it on the lightstand. These stands are about $3K.
Oh jkom51, that amethyst is sooo pretty, great buy!
