Update 1 : 4/22 so far I have been wearing the blue one 24/7 & it is still very sparkly and no stones have fallen out!

These are very sparkly and pretty! I got all of the 4 colors pictured. I saw a few in my local mall and the price of one was more than the price of the lot of 4 pieces and retainer! I did what other reviewers had suggested and super glued the bottom ball on for reassurance since both the top and bottom ball are removable. It is a tad long 7/16" standard length, as I typically wear 3/8" rings, but I expected this from reading the description and these looked too cute & cheap to pass up.

I am somewhat expecting that some of the stones will fall out... but I might buy some swarovski at my local arts and crafts store to replace any if that happens. I will probably update this review once I have had them for a while!
