They are very well made, the size is nice and the stones are firmly secured to the metal (which is very smooth and solid). The only problem I have with them is that the color of the quartz is not at all like it looks on the picture. The actual color of this kind of quartz varies in lightness and color quality so I really thought I was getting one like the picture (which would match a ring I have) but the smoky quartz in these is very dark and dull like watered-down coffee. You can still see through it and see that the stones have a very nice cut to them, just don't expect them to be as shiny and multi-toned as the ones in the picture. The quality of the jewelry is superb otherwise.
