Problem Identified: The natural variation of wood.
We at Imperial Optics use Natural Unstained Wood to manufacture the frames of each and every pair of sunglasses that we sell.
Depending on how old the tree is, where it grew up, where your glasses were cut from the tree the pattern/grain found on the sunglasses are subject to change.
Please understand that you are getting a natural product and given nature produces trees that are all unique. Our glasses are all unique.
No two pairs of Sunglasses we make are completely identical and that's just part of what makes them awesome.
Rest assured that the species of wood is identical to the one you ordered even though it might not look identical to the pair of glasses depicted on the web site.
