Nat 20 Relics

The top tier isn't about the material category — it's about the price you pay for precision and rarity.

Three sets currently qualify for Tier S. Two are natural stone: Blue Tiger's Eye at $114.99 and Lapis Lazuli (labeled "Blue Vein Diamond Cut") at $119.99. Both are cut from genuine geological material — Tiger's Eye with its natural chatoyant sheen, Lapis with the golden pyrite flecks that have made it a prestige stone since antiquity. The third set, Rainbow Crystal, is precision-cut K9 optical glass at $114.99 — priced here for its optical engineering rather than its mineral rarity.

These are not beginner dice. They are the pieces you buy when you've already owned the plastic sets and you want something that earns its spot in a permanent collection. Price, precision, and presence. That's the tier.
