Love Live! School Idol Festival Card #1023

What this character is holding is her birthstone (March 15), specifically an aquamarine.

How much does it cost?

(Kinokuniya Main Store, Singapore)

Pretty expensive actually. Especially considering this stone is probably 1 cm tall.

The stone Umi is holding definitely looks larger than 1 cm.

Still not as bad as this really tiny diamond that I also saw being sold.

I guess that's why that crane game I saw in Japan where you can grab real gemstones is fiendishly difficult. Quite a huge price tag for such a tiny diamond. Gotta get back your money's worth somehow.

I tried getting a ruby but ended up getting a clear topaz instead.

Come think of it, last time I got a gemstone from a crane machine it was a clear topaz as well. At least that one was set in a silver-plated necklace.

A perfect gift for a girlfriend.

If I had one.

I tried handing it off to my sister but she doesn't want it.

So now it's doing nothing but collecting dust.

No I'm not going to give it away.
