    In Standard Catalog of Gem Values ( second edition  pub, 1994 ) by
    Anna Miller and John Sinkankas, Persian spider web and Persian matrix
    are listed. " Gem grade Persian is listed at up to $ 150 ct. A grade
    Persian Matrix is listed at only $ 100 ct." The matrix is considered
    a lesser quality than spider web. 

    I have one piece of Persian spider web, from Iran,  which is the
    single finest piece of Turquoise I have ever seen. It was purchased
    from a retired individual who worked in Iran some years before. It
    is a white elephant, which is perhaps why it is yet unset.  I like
    spider web and matrix as well as multi colored turquoise.
