price check cluster jewel - affliction

https://steamcommunity.com/profiles/76561198354499069/screenshot/2475361870248198739//

Just got this jewel in affliction and still pretty new to game so unsure of price.

In case link doesn't work,
Large Cluster Jewel
- 8 passive skills
- 2 jewel sockets
- small passives give 10% spell dmg
- 1 added passive is Arcane Heroism
- 1 added passive is Essence Rush
- 1 added passive is Seal Mender

Any advice would be appreciated!

Thanks!
