EARRINGS
On the earrings and the gold of the temple is Spängchen grant 375. The gold material is relatively thin. As Grobmotoriker I've got a bit afraid to bend the ear plugs. The stone is not completely edged with gold (see picture). The Spängchen is very small. That could be a bit bigger. Again nothing for Grobmotoriker :-). The stones are loosely fitted in the socket. So not so loose that you lose the stones. If you wear the earrings, you can hear easily rattle the stones, as amended.
CONCLUSION
Through the thin material I find that the stud earrings are not for every day. Frankly, I would have been really disappointed if I had the total price you paid 68.95. With discount and voucher however I paid only about 17. And for the price, I find the earbuds ok. Color of stud earrings is great.
