Shine a tiny light from behind #2. If it's clear glass inside it's a Vitro Tiger Eye.

This sight has some great pictures, Ron. The first set of 4 shows it. http://www.akronmarbles.com/pontil_variations.htm

Ron, is one of the pontils (the third picture) ground?

This isn't my area, but I'll run "contemporary" up the flagpole and see if anyone salutes it.

If they're like this one I keep it. The glass drizzled around it then hardened/ I love this.

A stoned Peltier.

Perhaps my favorites are when MK ran out of purple for their Bumblebees and used other colors. Here's their brown next to a purple.

Carole - those two look-alikes (mother/daughter) marbles, are they Parrots? They sure look like it from here.

My humble understanding is that a Tiger Eye needs a top patch of a non-white color, bottom patch of white, and two ribbons (patches) forming a band around the center that is of 1 or 2 colors different than the top patch. 2 different colors make a Tiger Eye Tricolor Patch.

Galen hasn't written the definitive book on marble ID that I've been pestering him to do for years, so it's really anybody's guess right now. I've only seen Pastels in this size. IMHO size is not a determining factor.

WOW - you hear them, too?!?! Those Pastels are from the same time as the Parrots. The name was given by a collector and is catching on. They're about 3/4" and have translucent "brushed" patches on a clear base.

Don't forget my favorites - Vitro Pastels

BASE: Translucent off-white opalescent with a swirling look inside. Base is almost transparent when back-lit. PATCH: Opaque with “S” shaped edges

I was right ! I was right !! My convoluted logic worked. What do I win????
