These tiny hinged huggie hoops were exactly what I was looking for. Highly-polished shine, a subtle-yet-beautiful channel of tiny genuine diamonds, and good-quality manufacturing. The diamonds appear to be at least the stated quality, with good sparkle for such small stones. As shown in the image, there are seven little diamonds in each earring, for a total of 14; since the total carat-weight is 1/10th of a carat, that should tell you that these are less than 1/100th of a carat each. They are not made for children, they are simply a small adult hoop style. The silver is substantial for the size of the earrings, and the posts are thicker than average. On the inside of the hoop, the metal is stamped "CHINA", "925" for sterling silver, and the third stamp, under my loupe, appears to be "HN" inside an oval.

Regarding the clasps: The post fits into a hole in the back half of the hoop, and a notch in the bottom of the post catches onto the lower part of the hole. One of the pair I received didn't catch well, so I simply used gentle pressure with my finger to bend the post slightly downward--silver is quite malleable--and the clasp has never had a problem since, despite being worn to bed a number of times.

Diamond is my birthstone, and I bought these as a gift for my rather boyish girlfriend, to replace the plain small white gold hoops she now wears. After receiving them and trying them on, I'm tempted to get another pair for myself! They are comfortable and elegantly understated. If you're looking for something flashy, these are not for you, but they are perfect for that small hint of shine and sparkle. (I also ordered the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Round-Cut-Diamond-Stud-Premium-Quality-in-14k-White-Gold-0-10-ctw-G-H-color-SI1-clarity/dp/B008UYCMEU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Round Cut Diamond Stud Premium Quality in 14k White Gold (0.10 ctw, G-H color, SI1 clarity)</a>&nbsp;for her second earlobe piercings.)

Update: The 1/10th-carat diamond studs coordinated very well--just the right size. My girlfriend loved the look of these hoops, but the posts were a little too thick for her piercings...or maybe her skin doesn't like sterling silver?...so, poor me, I now wear them almost every day. ;) They are perfect with my larger pendants, as a big flashy earring would be too much with a big pendant, in my opinion. They are comfortable and stay put--I often forget I'm wearing them. She still has her diamond studs and her small plain white gold hoops, so I can't say I'm too sorry that they didn't work for her. :)
