First, this stone is approximately 1/2 inch from side to side.  I spent a bit of time trying to find out how big a 7.5 carat stone was and it wasn't easy.  The (stone and setting) is a beautiful thing.  The chain is a little stiff, and as with many of these pendants may eventually have to be replaced.

Now my wife has A LOT of jewelry, and I had a bit of a time finding this piece to measure it for this review.  She tends to wear some of this stuff once and put it away till she needs it for a particular outfit (or sometimes forever) so I had been pleased she had worn it a number of times recently.  I eventually found it on the dresser in a jewelry pouch she put together for a cruise in two weeks, so I guess it is a real hit.

If I hadn't already bought her a very nice topaz ring, or if topaz was her birthstone, I might buy this pendant and have it set in a ring.  In fact, Valentines is coming up, and I might do that anyway.

All in all, one of my better purchases (now what in the world am I going to do about Christmas.)
