While searching for marble crafts in Pinterest, I came across a pin to your site. I wish I had discovered you sooner. Marvelous site, wonderful collection of marbles, site organized quite well. So many choices.how do I choose? I will be delighted to shop here again. Thank you!
Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
This is a mineral sphere suitable for playing and collecting. This is hematite, the mineral form of Iron Oxide, and it is very dense, although not as dense as a
man-made steelie. It is opaque and exhibits a brilliant black metallic luster. It is harder than pure iron and is especially devastating in the marble ring
where is is not unusual for the target marble to crack under pressure! These choice examples came out of Brazil.
What is amazing about hematite is that in its natural rough state, it looks like an ordinary black rock, but polishing brings out its metallic lustre, as in these marbles. It is like a steelie, without the extra heft.
