Market analysis

Chisel speculation pumps gems now, guarantees a supply glut later. The Jeweller's Chisel turns low and mid tier gem cutting from a lossy grind into a near-guaranteed conversion, with a flat 20% success boost, a 10% chance to double-cut, and full guaranteed success on opal, jade and topaz at 62, 71 and 76 Crafting. That mechanical shift means the effective output of cut gems per uncut gem rises sharply the moment the update goes live, which is why speculators are already front-running it by buying uncut opal, jade and red topaz now while supply is still priced for the old, breakage-heavy system. Cut gem prices are getting dragged up alongside the uncuts purely on sentiment, even though the chisel does nothing to the cut gem market directly; it only removes failure risk on the input side. This is a classic pre-poll narrative trade, not a fundamentals trade yet, because the poll hasn't opened and the reward only ships in late July.

The uncut gem rally is a day-one-to-launch story that should keep building into the poll opening tomorrow and again into the actual patch date, since every incremental confirmation (design lock-in, poll passing) removes uncertainty and invites more speculative buying. But the trade inverts hard on launch day itself: once guaranteed success and bonus double-cuts are live, the same stock of uncut gems yields more cut gems, so cut gem supply effectively expands even if uncut demand stays firm. Expect uncut jade, opal and topaz to keep grinding higher through the poll window, peak into the patch, and then either flatline or reverse as the chisel's efficiency gains get priced in and skillers realize they need less raw material than before to hit the same cut-gem output.

Buyers here are flippers and jewelry crafters who read the guaranteed-success mechanic as a structural upgrade to gem cutting margins and want to be long the input before it becomes common knowledge; mid-level Crafting pures training toward 62-76 are also stockpiling uncut supply specifically to avoid wasting materials post-launch. Sellers are miners and casual gem farmers happy to unload uncut stock into a rising market rather than hold through the volatility of an unconfirmed poll outcome, plus existing cutters who are dumping current cut-gem inventory now while sentiment is elevated, anticipating cheaper, more efficient production once the chisel lands. Both sides are trading the same catalyst in opposite directions, which is exactly why the spread on jade, opal and topaz should stay wide until the poll result is known.

Hallowfell, Granite Dust, the Boss Teleport Scroll and the Necklace of Passage buff are real GE-relevant items but none of them carry the same weight as the gem trade because they're gated behind a boss fight and quest that haven't launched, and their supply/demand shape is still speculative rather than mechanically forced like the chisel's guaranteed-success math. Stardust and Goat Horn drops are explicitly called out as minor contributors and don't move the needle enough to trade. The competing Crafting method (Sunstone Golem Crafting vs Glassblowing) could theoretically bleed demand from seaweed and molten glass, but the blog says XP rates are balanced to be comparable, so this is a soft substitution risk rather than a confirmed shift and doesn't earn a standalone call yet.

This read changes fast if the Jeweller's Chisel fails its poll tomorrow; that would instantly kill the uncut gem premium since the entire rally is priced on the chisel shipping as described. It also changes if Jagex nerfs the guaranteed-success thresholds during polling discussion, which would soften the long-term bearish case on cut gems. Watch poll results closely, this is a binary catalyst trade.
