What the list shows

The list has 24 entries. 23 of them come with a rank table: the effect text with its value at every rank from 0 up to the gem's last rank, plus a secondary effect. The remaining entry is Whisper of Atonement. Its text says it is used only for augmenting Ancient Legendary items, and it has no rank table here. The matching Kanai's Cube recipe is Augment Ancient Item, which takes an Ancient item and a legendary gem.

Rank 25 and the secondary effect

All 23 gems with a rank table unlock their secondary effect at rank 25; below that, only the main effect applies. Some secondary effects reach into other systems. On the Gem of Ease, it sets the level requirement of the item the gem is socketed into to 1, and fittingly the cube recipe Remove Level Requirement asks for a Gem of Ease of rank 25 or higher. On Legacy of Dreams, the secondary effect doubles the bonus for Ancient items.

How the values grow

Every rank adds the same fixed amount. For the Gem of Ease that's 50 experience per rank: 500 at rank 0, 1,750 at rank 25 and 8,000 at rank 150. For many gems the rank 150 value is four times the rank 0 value, Simplicity's Strength going from 25% to 100% being one example. Others grow far more slowly: Red Soul Shard only climbs from 12,500% to 20,000% weapon damage. On Bane of the Powerful and Moratorium the scaling number is a duration rather than a percentage, from 30 to 180 and from 3 to 18 seconds respectively. Zei's Stone of Vengeance is the only gem with two scaling values: 4% per 10 yards and a 20% maximum at rank 0, 16% and 80% at rank 150.

Where the ranks end

The rank table in the game files goes up to rank 150. 18 gems run all the way, while five have a lower maximum rank: Iceblink and Boon of the Hoarder stop at rank 50, Legacy of Dreams at rank 99, Esoteric Alteration and Mutilation Guard at rank 100. Their values don't grow any further. Boon of the Hoarder reaches exactly 100% at rank 50, and Esoteric Alteration and Mutilation Guard both end at 60% at rank 100.
