We have synthesized large (0.7–1.0 mm) crystals of anhydrous, water-bearing, and Fe-bearing wadsleyite by means of growth from solution in the thermal gradient field. Nearly anhydrous (<68±4 wt ppm H₂O) Mg₂SiO₄ crystals were grown using K₂Mg(CO₃)₂ as a solvent at 16.5 GPa and 1700 °C. (Mg_0.92Fe_0.08)₂SiO₄ crystals containing 84±17 wt ppm H₂O were grown using 92K₂Mg(CO₃)₂-8FeCl₂ as a solvent. Crystals of Fe-free wadsleyite with 1496±117 wt ppm H₂O were synthesized at 1400 °C and 15.5 GPa by using 2KHCO₃-Mg(OH)₂ as a solvent.
