In the Gemmery, you can fuse four jewels of one type to create one jewel of a higher class.

Fuse jewels for Gold, instantly, or for Silver, which takes time. When your VIP status reaches level 17, the ability to fuse simple jewels instantly and for free will become available. Level up your VIP status in order to unlock free instant fusion of other types of jewels.

To obtain legendary jewels of levels I, II, and III, you will need to fuse other jewels. You can fuse them instantly in exchange for Gold, or spend some time fusing them. At certain VIP levels, you'll be able to fuse upgraded legendary jewels instantly and for free.

Adomi jewels don't have any types or levels, and you cannot receive or find them – you can only create them using other jewels.

Adomi jewels are always displayed in the Storeroom tab if you have at least one regular jewel of any type.

Adomi jewels can be created instantly for Gold, or for free, which takes some time. At certain VIP levels, you'll be able to create Adomi jewels instantly and without expending any resources at all.

If you have eight or more jewels of the same type, you can perform a bulk fusion. When you tap the "Fuse" button, an additional window will open in which you can fuse an unlimited number of jewels.

For example, if you have 12 Corals of usual type, then one bulk fusion will produce 3 Corals of unusual type.

In addition, you can change the number of jewels for bulk fusion using the special slider at the bottom of the window.
