These are possibilities for Moonstone and Agate as far as weapons:

And of course there would be two of them. As for their gem fusion I would say Desert Rose personally, I like the description for it.

For me and Jade I'd say the following for weapon:

It's kind of hard to find something though because Jade has a blade throwing weapon which is considered ranged and can be used for melee technically speaking, so that only thing I can think of is changing the form to make it easier to hold and throw. :/

As for Moonstone and Jade, how about a weapon themed after a rail twirler? Its would basically be two swords that has a groove along the dull edge and in the groove you could roll a bladed ring like Jade's along it and between the two swords and then swing the sword to throw the bladed ring at them. And while they try to block/defend against it you would swoop in with the swords and attack.

Also, I think the Ajoite would be a good gem fusion for Jade and Moonstone.
