Some people today have decorative weapons on their walls. They would be useless in real battles, but look good. Some become antiques and heirlooms even.
Why assume our ancestors were different to us?

...(clear quartz is stone, not "crystal")
Quartz is an igneous rock made out of molecules of silicon and oxygen atoms held together in a crystal pattern. All of the silica and oxygen that make quartz came originally from the insides of stars, and it shot out of the stars when the stars exploded as supernovas. Then the silica formed part of a nebula, a dust cloud floating in space.
...There are many different kinds of quartz, depending on exactly how it cooled down. Some kinds have large crystals, and some have very small crystals. Small amounts of other materials that get into the stone can give it colors - quartz with a little iron in it is a pink color or a purple color called amethyst. Some kinds of quartz are nearly transparent (you can see through them).
...Most glass is made by melting sand made of tiny bits of quartz. People also use quartz crystals in various religious ways.
Quartz also often becomes a part of other kinds of rocks. Some igneous rocks, like granite, have quartz in them. Some sedimentary rocks, like sandstone and limestone, also contain quartz. And some metamorphic rocks, like marble, have quartz in them too.

It is certainly a offering or funerary gift, but it was not found with the body, but in an upper chamber,
So I think it is a remembernce type gift to the dead, from a crasftsman.
The quartzite is not native to the area, but comes from "several hundred Km away from Valencia", I have read that knappers in the region have a history of using quartzite for points, even when cherts and flints are nearby and more readily available. This preference goes all the way back to Solutrean times.
Quartz is a rock or stone. It's crystal too.

That would be pretty tough to make... I wonder if these were used specifically for sacrifices, etc...

Yup!
Cool, huh? Love it that the silica and oxygen that make quartz came originally from the insides of stars, and it shot out of the stars when the stars exploded as supernovas.

Same for Cobalt, Nickel, Zinc, Gold, Tin, Silver, Lead, Arsenic, Iodine, and every other element heavier than iron.
The pressures and heat needed to nucleosynthesize an element heavier than iron requires a supernova.
Oxygen and silica doesn't require a supernova to be nucleosynthesized; they are made inside a star hear the end of its life, and can be released in a nova event -- but they do come out of a supernovae, too.
