Rubellite Earrings

Taken all the way down to base materials, one Rubellite Earrings is 2 crafting steps deep and needs 2 intermediates — Rubellite ×2 and Electrum Ingot ×1 — which resolve to 2 distinct raw materials totalling 6 units, plus 27 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 643 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 21 Wind Shard and 6 Fire Shard.

Every step is Goldsmith work, from a Lv 41 intermediate up to the Lv 50 finish, so one class covers the whole chain.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
