They Make Shoes Out of Rubies, Right?

It seems that they have run through the list of metals to classify credit cards. Silver, gold, platinum, titanium. Just not impressive enough anymore.  Yes, they have moved on to precious stones.Today I received an offer for a Sapphire Visa card. I have been preapproved for a ridiculously high credit limit. But they want an annual fee. And my firstborn child. And it turns out that the card itself isn't actually made of sapphire. Nor does it have some tiny cute gemstones embedded in the plastic. Thanks, Visa people, I'll pass on this one. Do let me know when you are offering sapphires suitable for mounting in, say, a silver, gold, platinum, or titanium setting. I might take you up on that.
