Yes. Jewelry really matters. Why? Because of its symbolism. Because it's precious and worn directly on our bodies.
We treasure jewelry the most for its capacity to represent our past, our victories, our memories, our love, our deepest wishes, and our most outstanding achievements.
Jewelry is fashion, status, and fun, which is also true. But the reason it matters and has mattered for thousands of years is because of its capacity to remind us of who we are.
