Qingu turquoise is a rare and highly sought-after gemstone from the Hubei province of China, a region renowned for producing much of the world's turquoise supply. It is celebrated for its diverse and rich color spectrum, which can range from vibrant, deep ocean blues to appealing spring greens and various bluish-green shades.

A key characteristic of Qingu turquoise is its intricate matrix, the remnant of its surrounding rock, which often forms distinctive, web-like patterns in dark brown or black that contrast beautifully with the host stone. This unique "spiderweb" matrix gives each piece a one-of-a-kind appearance, similar to a fingerprint. The material can be found in a natural state or as stabilized material, where clear epoxy is applied to harden the stone.
