The Jeweler's Last Stone is a Demon Unique ring with no boss attached: it drops anywhere in Hell, most often from H6 up (rarer below that home difficulty, never above it), and nowhere else. Every copy is item level 110, and there 0.2% of what falls comes up Unique. It is built on Immaculate Ironglass Ring — step 6 of the Ironglass Ring line, item level 80 and up.

It always rolls the same numbers: +52 Armor, +8% Critical Chance, +24% Critical Damage, +12% Critical Chance, +52% Critical Damage, +12% Power and +34% Cooldown Recovery.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries The Jeweler's Last Stone — +50% Critical Damage. +12% Critical Chance.

“Cut so fine it argues with the light.”
