I could help with the weapon ideas, if you'd like.

Aquamarine + Spinel = Larger crossbow perhaps? Maybe some sort of staff that fires rounds of ice.

Aquamarine Sodalite = [url=http://fc01.deviantart.net/fs51/f/2009/284/a/6/Speed___Halberd_01_by_Sylvain_Klein.png]Halberd[/url], maybe double sided or can become double sided.

Emerald + Spinel = [url=http://pre15.deviantart.net/8fd8/th/pre/f/2013/022/1/f/monster_hunter_sword_by_zer7rax-d5sbnsp.jpg]Double bladed sword thing[/url]. Bolts of energy fire from between the two blades.

Emerald + Sodalite = [url=https://www.screenused.com/images/mummyreturns/mummy_returns_sword_4.jpg]This???[/url]

Amber + Spinel = [url=http://img-new.cgtrader.com/items/75094/large_battle_hammer_3d_model_stl_1176440b-2c29-46fd-aa38-6e774b0f6f54.jpg]Battle Hammer on a chain.[/url] The chain can extend or shorten at will, and two could be used at a time due to size.

Amber + Howlite = [url=http://www.thelandofshadow.com/wp-content/uploads/2014/01/UC3015.jpg]Mace?[/url] Other blade-based bludgeoning device?

Amber + Evenkite = [url=http://orig07.deviantart.net/3417/f/2011/027/9/2/926eed890b4ba73ce252f3020ce26d88-d386rkj.png]bladed hammer.[/url] The neck of the weapon could be much larger than shown in the picture.

Amber + Sodalite = [url=http://vignette2.wikia.nocookie.net/orcsmustdie/images/0/0a/Weapon_Vampiric_Gauntlets.png/revision/latest?cb=20120423155331]Heavy bludgeoning gauntlets I guess.[/url]

Spinel + Howlite = [url=http://pre07.deviantart.net/92a2/th/pre/f/2014/242/a/e/futuristic_battle_axe_concept_by_alphaprimesaviour-d7x8o4p.jpg]This thing[/url]

Spinel + Zircon = [url=http://thecooleststuffever.com/sites/default/files/styles/product_main/public/fantasy_curved_knife.jpeg?itok=l3MoQ54h]???[/url]

Spinel + Evenkite = [url=http://krimg.joymax.com/property/silkroad/silkroadonline_6/gamedata/item/Europe/crossbow_view/14.jpg]crossbow staff pike.. thing.[/url] It would act as a regular staff/pike, but the arms of the crossbow would swing out from the staff itself.

Spinel + Sodalite = I'm thinking some sort of gauntlet shield with a the crossbow built into it.

Howlite + Zircon = hmm....

Howlite + Evenkite = [url=http://img2.wikia.nocookie.net/__cb20130102231332/runescape/images/3/3a/White_halberd_detail.png]??[/url]

Howlite + Sodalite = Just a heavy axe similar to Howlite's would do I guess.

Zircon + Evenkite = nothin'

Zircon + Sodalite = nothing once more...

Evenkite + Sodalite = once again nothing...
