Pls identify this.a normal pic and a pic with uv varies from 3.20 to 3.60.

At first glance it look like quartz. How about mineral's hardness?

Pretty sure harder than quartz.

We need better images... However, the color and specific gravity suggests topaz (assuming that was done correctly). But can't tell just from images as it really looks like quartz to me...

Looks like quartz to me as well.
The purplish colour under UV is just the reflection of the light off the specimen.

Topaz has a perfect cleavage and I see none on your specimen. As the others say it looks like quartz.

Also - remember which UV light - short (SW), mid-range (MW), or long wave (LW)? Some minerals respond to different waves - sometimes in different colors or different intense (e.g. Nuevo Leon or Terligua calcites).

Shortwave uv light only and i think this is better pic.
