Vertu has added one more phone to its super expensive portfolio. It hails from the Constellation range called as Constellation Pure. The name is derived because of the purity in the uniform coloring process that took two years of research to perfect it. The phone will come in two colors – Pure White and Pure Black. The Pure White variant has polished steel with white ceramic keypad, scratch resistant materials and white leather on the back. On the other hand, the black version has PVD steel, black ceramic keypad and black leather on the rear. This will be a limited edition handset with only 2,500 units each up for sale.
