Upgrading Cyrce’s Circlet
Cyrce’s Circlet, the new BiS ring you can empower with various gems, can be upgraded to Item Level 639!
To upgrade the ring, you will need 
Raw Singing Citrine. This item is currently available on a vendor called Citrinataur on the PTR, but we assume you’ll need to complete some sort of quest to get it when the patch is live.
Raw Singing Citrine increases the item level of the ring by 3 every time you use the consumable. The ring can be upgraded to Item Level 639.
