As can be seen in the photos above, the cone beads have a more satin like matte finish where the cylinders have a very bright gold foil with gold glass outside. All beads show some black at the stringing hole but it does not affect the bead's use in a design.
The 7 Cone beads measure 9mm at the base and 5mm at the top. They are 18mm tall and are formed in a triangular pattern.
The 10 Cylinder beads are actually flat, more like a rectangle, and measure 10 x 6mmx 23mm long.
These two styles are a nice contrasting appearance.
Photos above are a good representation of the actual.
