These are beautiful, and I feel very proud to give them to my niece for her 21st birthday, an occasion which requires an extra-special gift; however, there are a couple of things the buyer should know:
First, the sterling silver chain is about the thinnest and most delicate I've ever seen, so this is not for someone who doesn't care for things well or is clumsy.  Also, the colors of the amethyst and the blue topaz, and to a lesser degree, the citrine, are not true on the website.  The blue topaz almost looks clear.  Only in the light can you get the traces of blue, and the amethyst is very light as well.  The peridot is gorgeous, and the garnet is a dark stone to begin with, so that's not a problem.  They did not come in blue pouches, as was specified; rather, they came in five small black boxes which were put together with a white cardstock sleeve in a long strip.  I ordered the matching earrings as well, and they do match perfectly.  Be aware that nowhere on the boxes does it tell what the stones are or that it is sterling silver, or any information whatsoever.
So, except for the washed out color on a couple of the stones, I am thrilled, especially with the price (I also got the 30% discount).
