[QUOTE="22shells, post: 391232, member: 3817"] Did some hardness tests: The chalcedonic type rocks- must be fairly hard, not scratched by $2 coin (left coin traces on rock), not scratched by pocket knife, not scratched by sharp quartz crystal fragment (wore away a bit of the quartz) The "calcite" type crystal- seems soft, not scratched by $2 coin (coin isn't real sharp), scratched easily by pocket knife, scratched easily by sharp quartz crystal fragment. Guess that rules out topaz? Only other thing it might be that I can think of could be aquamarine, but I doubt it. Likely area for aquamarine and it has been found in the area, but the shape of it doesn't look right for aqua to me. [/QUOTE]
