Golden Hills Turquoise

Golden Hills turquoise is a rare, premium gemstone from the Altyn-Tyube Mine in Kazakhstan, discovered around 2013. It is famous for its unique periwinkle or lavender-blue color and contrasting chocolate-brown or reddish matrix.
Unique Qualities
Color: Striking light sky-blue, lavender, or periwinkle shades instead of standard deep or greenish-blue.
Matrix: Features a fine, webbed, or spider-web pattern in burnt umber, lavender, or deep brown.
Purity: Considered one of the most chemically pure and hard varieties of natural turquoise available. 
Mining and Rarity
Winter Only: Mining happens strictly during freezing winter months because the remote site floods heavily the rest of the year.
High Value: Limited seasonal supply combined with high demand from Southwestern and Native American-style jewelry artists drives up market prices.
