Each piece is about 2" tall to 2-5/8" tall, the insertion gap is about 3/16" (5mm). The wearable for each piece is about 1/4".

Ruby - These pieces are a vibrant ruby red, with the "eyes" of the wood retaining some their original tan maple color.
Emerald - Ranging from a deep emerald to a turquoise, these, similar to the red, have retained the tan "eyes" of the maple wood.
Tan - Because these pieces have a lighter dye, the natural marbling of the wood is very pronounced between shades of tan and dark brown.
Royal Purple - In most of the purple pairs, the dye has covered the "eyes" of the wood, leaving only specs of tan within the rich swirls of purple.
Red/Purple - Dyed using two colors, these pieces are more complex than the single colored pieces, and still retain a moderate amount of the tan "eyes."
Green/Purple - With varying amounts of dye, some pieces are more purple, while others are more green, and the number of "eyes" that remain intact changes from piece to piece.
