Facet Ring of Healing ★★

Taken all the way down to base materials, one Facet Ring of Healing is 3 crafting steps deep and needs 4 intermediates — Grade 2 Mind Alkahest ×1, Onyx ×1, Prismatic Ingot ×1 and 1 other — which resolve to 7 distinct raw materials totalling 18 units, plus 26 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 1,038 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 14 Wind Crystal, 4 Fire Cluster, 4 Wind Cluster and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 80 and Alchemist to Lv 80 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Prismstone (4:00, 16:00) and Raw Onyx (0:00, 12:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Prismatic Ingot has the widest use: 79 recipes call for it, spanning five of the eight crafting classes.
