Quartz or diamond ?

[Salvatore]

Was looking to identify these two pieces with different views of each in two separate collages of photos of each.One of the two pieces has several cubic shapes that stand out when exposed to light. Any opinions would be helpful in identifying what kind of minerals they are.

It is quartz,and can have any number of inclusions

I don't agreee. Quartz rarely are found singularly unless it's in a geode or when someone physically breaks a piece from a cluster. I don't see any body plus quartz are rarEly formed in a singlular form.

Massive quartz, i.e. from quartz veins are very, very common.

I second EU. Massive quartz. The first piece shows some internal faceting or fractures and the second has iron mineral inclusions as well as staining from what I can tell.

Caleb12, please take the time to visit a real library and open real books on rocks, minerals and geology. Most of us here in the rock forum have a lot of experience with various minerals with the most varied probably belonging to Quartz and silicate materials.

Salvatore the cubic shapes are likely fractures or contact points among the individual crystals in the formation.

Thank You for helping to identify these two pieces and it makes me want to read up on more information on minerals and rocks. Going to list one other pieces today that has me questioning what kind of mineral it is.Thanks once again for your time.
