Starfury weapons can also be obtained, if you missed them when they last appeared.

How to Get Starfury Armour
First up, you'll need starlight ore. This can be won on Treasure Hunter, obtained by mining regular rocks (not the Shooting Star D&D) and traded on the Grand Exchange or directly between players.
Click on the ore to create starfire armour or weapons. Each of the three armour sets has six pieces, and all starfire gear can be switched between level 1 and level 40 stats. Each one you create grants you Smithing XP equivalent to the ore spent.
The ability to craft the armour unlocks gradually as the six days go by. Weapons can all be crafted from the start:
10th September: boots & gloves
11th September: head and legs
12th September: chest
13th September: cape
Note that all days start at 00:00 UTC (game time) and that each item can be crafted from date of unlock until the ore is removed after 28th September.
If you prefer, you can exchange starlight ore directly for Smithing or Mining XP – up to 10,000 pieces per day. To do so, speak to Ivar in the Artisans' Workshop.
You can also collect starborn diamonds via the same methods as the ore (although they're much rarer), or by converting starlight ore. They're used to upgrade your starfire gear to the improved starfury versions. To do so, use a starborn diamond on the item to be upgraded.
This confers a range of benefits:
Highest stat tier unlocked (level 70 requirement, non-degrading).
1500 Mining XP per item upgraded.
Armour can delay depletion of the Seren Stones in Prifddinas when mining there, allowing for prolonged training per stone.
The cloak acts like Ava's Accumulator, if you've unlocked it.
Armour pieces act confer the benefits of their equivalent golden mining suit piece, if you've unlocked them.
Each item can be created and upgraded only once.
Starfire and starfury armour and weapons at level 70 have slightly lower stats than Barrows armour, although they do not degrade.
Ironman players can obtain starfire or starfury weapons and armour, but can only use the versions with level 1 stats, and cannot benefit from the Ava's Accumulator and golden mining suit effects.
You have until 23:59 UTC on the 28th of September to use up any starlight ore or starborn diamonds, after which they will disappear from the game.
