Intrinsically we sense the rarity and value of jewels, just as we intrinsically know that turds are not rare or valuable. If you wear nice jewels, people around you will notice. Most (but not all) will want to sleep with you and share with you a life of leisure, wealth and power. It’s quite natural. Wear jewels like a peacock spreads his tailfeathers. Gold ropes and rocks……the human version of 8 point antlers or bright blue butt cheeks. It’d be fitting to see some more wildlife with big gold watches and chains nowadays, maybe even some platinum grillz to keep the prey knowing who’s on top.
In this world, you get iced up elk and polar bear twinkle.
