I purchased one strand of the 4mm faceted cubes, which ended up being 90 beads. The listing photos are an accurate example of what you can expect as far as color consistency and what to expect; they range from green to yellow and orange, and span from being very dark (a small few) to very light (the majority of beads). Some are very, if not entirely opaque but most beads (including the darkest bead of a dark amber color) have at least some transparency.
For the shape and cut, they are consistent. Some are a little smaller, maybe a few a little more round in places, but overall exactly what I think is to be expected.
Photo was taken in low-medium natural light. Photo has been edited to slightly increase overall brightness.
