Birdseye Turquoise is a term that describes turquoise that is somewhat similar to spiderweb turquoise in that it is made of an aggregate of many small nuggets but instead of a dark matrix like spiderweb, Birdseye Turquoise is light blue turquoise with a darker blue turquoise matrix.
The result when the stones are polished or cross cut and polished is that there are many small areas of lighter blue stone encircled by darker blue matrix like a bird’s eye, thus birdseye turquoise. Sometimes it is referred to as “water web” turquoise.
Although the term refers to turquoise from any mine that looks like this, there are only a handful of mines that produce birdseye turquoise – namely Turquoise Mountain, Kingman, and Morenci. Turquoise Mountain (closed in the late 1980s) is loacated near the Kingman mine in northwestern Arizona.
