This is a very nice quartz rutilated from Brasil...14cts and 14,71x14,71x7,67mm
We have always been fascinated by rutilated quartz, the clear or smoky quartz with inclusions of rutile (titanium dioxide). The rutile needles form lovely patterns like miniature sculptures. Every stone is quite unique -- some have delicate hair-like intersecting needles; others have dense clusters of thicker needles.
According to Modern Jeweler, the demand for rutilated quartz by jewelry designers is so strong that nice cabochons are selling for as much as $20 or more per carat in the USA. One dealer explained it this way: "When you think of what this gem offers in terms of eye appeal and artistic potential to consumers hungry for things that are new and different, rutilated quartz would still be a bargain at twice the price."
