These are unheated imperial topaz. A beautiful non-heating OH type with good luster and transparency. The color is a clear orange like sherry. There are some inclusions when viewed with a 10x loupe, but they are barely visible to the naked eye.
(The last two photos were taken with a dichroic mirror.)
