What is K2 Granite? 
"K2 Granite," also known as "K2 Jasper," is an extremely interesting rock and lapidary material from Pakistan that is like an eye magnet for anyone who sees it for the first time. It is a bright white granite that contains sharply contrasting orbs of bright blue azurite. The azurite orbs range from a few millimeters up to about two centimeters in diameter. On a broken surface or on the surface of a slab, the blue orbs look like drops of bright blue ink that splashed onto the rock. Upon closer examination, however, you will see that they are actually spherical in shape. 

Although K2 Jasper is the most commonly used name for marketing this material, it is definitely not jasper. If you examine the rock with a magnifying glass, you will see cleavage faces of feldspar minerals and black flakes of biotite. 

The white granite is very fine-grained and composed of quartz, white feldspars, and biotite. Some specimens show strong alignment of the biotite grains and could be called “granite gneiss.”

Examination of the azurite spheres with a good hand lens or microscope reveals that the azurite is present along mineral grain boundaries, within tiny fractures, and as a “dye” penetrating the feldspar grains. The azurite is a secondary material that clearly formed after all of the other minerals in the granite had solidified from the parent melt.

People Don’t Believe It’s Azurite

Many people see this material at mineral shows or lapidary shows and immediately think that the round blue dots have been produced with a dye. When they ask about the identity of the blue material and learn that it is “azurite,” they usually have a hard time believing it because white granite and azurite rarely occur together. For most people this is the first time that they have seen the two materials in such close association. 

Some specimens also have small areas that are stained green with malachite. In the close-up photo of K2 granite below, you can see dozens of small green malachite stains. 

Where Is K2 Found?

K2 granite is named after a mountain in the Karakoram Range near the border between Pakistan and China. K2, also known as "Mount Godwin Austen," is the second highest mountain in the world. The azurite granite is found in colluvium near the base of the mountain. It is in a very remote area visited by very few people.

Lapidary Properties

K2 granite cuts, tumbles, and polishes beautifully. Due to its high feldspar content, it can be easily cut with a lapidary saw and shapes quickly on a diamond wheel. Although azurite has a Mohs hardness of 3.5 to 4, the blue dots have the same cutting and polishing properties as the surrounding white granite. This is because the azurite exists as a stain rather than as discrete mineral grains. 

K2 shapes and polishes well in a rock tumbler to produce tumbled stones. It also cuts attractive spheres. Cut beads are not seen in the marketplace. This is likely because if you cut ten pounds of K2 into 1-centimeter beads, very few of them will display the blue azurite color. 

K2 is relatively durable in jewelry. The feldspar minerals in K2 have a hardness of about 6 on the Mohs scale and will be scratched or show signs of wear over time if subjected to abrasion or impact. K2 is therefore not a good stone for mounting in a ring or bracelet. 

K2 attracts a lot of attention at gem and mineral shows. The rare combination of azurite in granite starts a lot of discussions, and even the occasional argument. Thus far, K2 is not extremely expensive. Great material can be purchased for about $30 to $40 per pound. This price is similar to what is paid for nice specimens of many popular agates and jaspers. The best material has numerous, randomly spaced azurite stains on a bright white granite background.
