Please consider adding RS2's Rogue (Post-miniquest after Summer's End).
RS2 Features: Purchases unenchanted jewellery at high-alch prices.
-> Useful to get rid of your crafted stuff without needing to alch it.
OSRS implementation:
Implement him as-is somewhere thematic, for example as a (hard) diary reward in Varlamore. To be more in-line with RS2, you might need to do a miniquest to unlock him. It could be combined with the diary idea by making something post-miniquest a diary step.
Additionally, reduce the gp given per item by 200gp (spell cost equivalent, roughly). If this results in a value lower than the low-alch value, the low-alch value is given instead (mostly applies to standard gold jewellery).
The current "solution" to quickly get rid of them is to use the port sarim jeweler for non-bracelet jewellery / west ardy, selling like 5 - 10 per world and hopping. Shopscape bad, thematic alternative good.
