I highly recommend this shop for zultanite items.
Wiki: Zultanite is a trademark for a gem variety of the mineral diaspore, mined in the İlbir Mountains of southwest Turkey at an elevation of over 4,000 feet. Depending on its light source, zultanite's color varies between a yellowish green, light gold, and purplish pink.
This stone is very unique and mesmerising. Therefore I had to get some before leaving Turkey. But my budget was tiny (under €50/item).
Finding nice zultanite items with a nice sales person is quite hard... most of them think you're filthy rich and ready to spend thousands of dollars... very annoying.
This zultanite shop however is managed by a very nice gentleman and he lets you look around and gives very fair prices right away. Stop by his shop if you're in Marmaris read more
