These were a little smaller than I expected...I didn't read the measurements. However they are beautiful, and stand out just as well as a larger stone would have. Chalcedony tends to be an expensive stone, so I believe it was money well spent for these.
This necklace looks just as good in person. My only complaint is that the jump ring (the ring that you attach to the clasp) is very small, so putting it on yourself may be a bit tricky.
