These crystal shards were mined from the rocks around Ulta Metamagicals. Tekki is using them to tune her upgraded asura gates.
— In-game description
These crystals are used to increase progress towards "Assist Ulta Metamagicals with their asura gate research", a level 24 hub in the Brisban Wildlands. The tooltip suggests that Tekki will take these crystals, but only Ulta Crystal Gatherer (near the Ulta Metamagicals Waypoint) will accept them.
