Blue Pearl is a charcoal to dark gray stone seeded with crystals that fire blue, silver and occasionally gold when light reaches them at the right angle. The ground reads as a deep, even gray, and the shimmer lives inside the slab rather than sitting on top of the polish.
Walk the length of a Blue Pearl counter and the surface keeps shifting as new angles open up. Stand still and it settles back into ordinary gray.
Where Does Blue Pearl Granite Come From?
Every slab is quarried in Norway, in the Larvik district south of Oslo. Strictly speaking the rock is a larvikite, named after that same district, rather than a granite in the petrological sense.
The trade has classified it as granite for decades, and in a kitchen it behaves like one in every respect that counts. Norway is the only commercial source there is, and that scarcity accounts for much of what it costs in Cebu.
Why Does It Shimmer?
The flash comes out of the feldspar crystals locked inside the rock. Light enters a crystal, bounces off the layers within it, and those reflections interfere with one another so that some wavelengths cancel and others are reinforced.
What survives the trip to your eye is a flash of blue, silver or gold, depending on where you happen to be standing. Nothing in the polishing produces it, because it is an optical property the rock already carried.
What Does GT Mean?
GT is a grade rather than a variety. Blue Pearl is graded on how large and how densely packed the shimmering crystals run, and the grade moves both the appearance and the price. GT is the grade held at our Cebu slabyard.
When two Cebu quotations disagree, compare grades before you compare figures. Two suppliers can both write Blue Pearl on a page and mean visibly different material.
