I understand art and ingenuity, but encrusting it with diamonds and pearls seems a little excessive. Vincent Van Gogh died poor, and his paintings are worth millions now. No diamonds needed.
Diamonds aren’t “needed” on anything outside of a few industrial applications, truthfully. But, they’re beautiful and so they’re wanted. To each his own, if you find it excessive then to you it is. Don’t buy any. Kinda cool how that works, isn’t it?
