YSL Arty Rings for Small Hands?

I realize I'm about one year behind on this one. I don't really pursue "trends," and thus consider myself a clothing blogger and not a fashion or style blogger. But oh, these much-hyped rings are really quite beautiful in person.

I first read about these rings over a year ago, but size 5 was frequently sold out. I was also worried the large stone would look like an Easter egg swallowing up my child-sized paws. Then I saw Tiffany's blue one in action and loved it on her petite hands. In person, I don't find the size overwhelming at all. What are your thoughts?

On a whim, I checked Saks' website last month and saw that not one, but eight colors were available in size 5! I wish they made the stones interchangeable with magnets or something :

YSL size 5 may not be small enough right out of the box for those with tiny fingers. There was definitely some sizing inconsistency too between the two I received. The smaller size 5 fits bigger than my size 6 Forever21 rings! Thankfully, after my post about ring-sizing, Jenny shared a tip (thank you, Jenny!) involving double-sided mounting or foam tape which has worked amazingly on all my rings.

To sum it up...

Arty Likes:
- Beautiful bold design and color. I can see someone (my future child, perhaps?) finding this 20 years down the road and loving it as a vintage piece.
- Unique. And I use this word relatively. This ring is "last year" amongst the world of trendy fashion bloggers, but I have not yet run into anyone in conservative Boston with this, and it was unique to my coworkers and friends.

Arty Dislikes:
- Expensive for costume jewelry (but for designer costume jewelry, it's actually not bad)
- The oval is made of glass. That means it could probably shatter or chip on light impact. My F21 oval ring already shattered after it flew off my finger. But that was $6...
