Stone Story
Jade doesn't sparkle. It glows. Its optical character comes from internal texture and translucency rather than faceting brilliance, which is a different light experience from emerald or tsavorite: neither better, but genuinely distinct, and understanding that distinction is what makes choosing between them a real decision rather than a default.
