Wow, this is just an amazing Sapphire.  The main color is actually Purple, as noted in the appraisal.  But because of the color change effect, the camera only picked up the bright Blue.  Cameras have difficulty with color change stones.  This stone is comparable in color to the most richly colored Tanzanites.

This gemstone comes with the pictured appraisal certificate from a GIA Graduate Gemologist in the San Diego Jewelry District.  For those who don’t know how appraisal values are determined, there are two ways that appraisal values are determined.  Some appraisers give the retail value of the piece, whereas others give a replacement value.  The appraisal for this stone is not a retail value.  As you can see, it’s a replacement value, meaning, it’s the value it would cost an insurance company to replace the item.  And because insurance companies use wholesalers to replace lost or damaged goods, replacement values are considered wholesale, generally around 50% of a retail value.  That means that this stone, in a jewelry store, would sell in the range of $6,150.  And as you can see, the price we are asking is well below even the wholesale replacement value.

I took pictures of this stone in high magnification against a   white background   to give     you the best idea of color and quality.    As a certified   gemologist I can verify that the above description is         accurate and   that this stone/stones have been tested in the gem lab to    verify     identity and natural origin.
