The blue topaz is what caught my eye, as it is my young niece's birthstone and I wanted to give them to her for her b-day this year. They are simply gorgeous! The blue topaz is sky blue, but not too light. The peridot is my fave, and I am keeping them for myself! The citrine is much brighter than pictured. Overall, I am very satisfied and would recommend. The only issue I noticed is that one of the amethysts is slightly bigger than the other (about 0.5 mm) but I don't think it will be obvious one they are actually set in to castings. Other than that, all of the sets are perfectly matched as pairs, giving you the option to use them as earrings."
