Archie,

Below you will find two different examples. In the top examples, you will notice that on the left chip, if you start at the yellow insert and go clockwise you will find the inserts in the following order:

Yellow, Gray, Blue

On the right example, the inserts are in the order of:

Yellow, Blue, Gray

If this chip had the same inlay on both sides, you would get both versions in the same chip. But, since it has different sides, the only way to get both insert patterns is to have 2 chips.

On the bottom left chip the inserts are in the pattern:

Blue/Orange, Blue/Orange, Blue/Orange, Blue/Orange

On the right example, the inserts are in the pattern:

Orange/Blue, Orange/Blue, Orange/Blue, Orange/Blue
