I just got a box of minerals from Pakistan which contained 2 pieces of an unidentified material. These are unfamiliar to me, and I need some help.

The color is a sea green, translucent. The crystals are well formed, appear to be perhaps Tetragonal or Orthorhombic. They have 4 distinct sides, diamond-shaped in cross section, with  sharp low angle edges on 2 sides. The hardness is greater than 6. The matrix is quartz, evidently a pegmatite mineral. No locality, but all of the others from this supplier were from Afghanistan, Pakistan, and Waziristan.

I suspect they are Topaz, but the shape and color have me questioning this.

I posted photos on http://www.connroxminerals.com/temp.html

Any thoughts?

Thanks...Larry
