Looks to be a mix of clear to smoky quartz rock crystal fragments with some amethyst *the purple*. If there are any topaz in there it'd take an in hand examination
to find them as none of the pieces exhibit any clear indications of topaz to me.
I agree DDancer. Very nice crystals. Those pale gold colors make amazing faceted stones!
The pink is likely Rose Quartz. It fits the color perfectly. Morganite is usually very pale pink (almost to the point of hard to distinguish)and yours is pretty saturated with color. Of course, it's almost impossible to identify anything for sure from a photo but I saw some interesting striations on one piece. Can you find this one and take a close up?
After you mentioning the striations, I looked at the gems and all of them have the striations. Except the rose quartz. I looked up gems with striations. Here is what I got. http://gem5.com/tag/striated/
I'm pretty sure these are citrine, would you agree?
