It costs 900 jewels to build and 1500 jewels to upgrade to Lv2. You use it to upgrade or downgrade awakening materials.

Lv1 upgrades:

- 4x Stone (S) + 400k Gold + 400k Ether + 400k Iron --> 1x Stone (M)

- 5x Stone (M)  + 500k Gold + 500k Ether + 500k Iron --> 1x Stone (L)

 - 9x  Stone (L)  + 700k Gold + 700k Ether + 700k Iron --> 1x Orb

Lv1 downgrades:

- 1x Stone (M) +  400k Gold + 400k Ether + 400k Iron --> 1x Stone (S)

 - 1x Stone (L) + 5 00k Gold + 500k Ether + 500k Iron --> 1x Stone (M)

 - 1x Orb +  700k Gold + 700k Ether + 700k Iron --> 2x Stone (L)

 According to the upgrade screen, at Lv2 the S->M and M->L numbers change to:

 - 3x Stone (S) + 300k Gold + 300k Ether + 300k Iron --> 1x Stone (M)

 - 4x Stone (M)  + 400k Gold + 400k Ether + 400k Iron --> 1x Stone (L)

 I haven't upgraded mine yet so that's all the information I can access at the moment.
