Here are two klonks sized strands from the gem show. I have not strung them up yet. My 12mm is there to compare sizes. As you can see, one is slightly larger and the other is distinctly larger.
The skins are in good shape and it has patches of brilliant luster on every single pearl, but patches of dull as well, on most. What is remarkable is that it is huge for FW, but being a lower quality pearl, it has a comfort level with wearing it in most everyday situations, compared to a gem quality strand.
