Lab Wakefieldite Fancy Cut Gems aka Yttrium Orthovanadate Nd:YVo4

These are faceted lab-grown wakefieldite, also known as yttrium orthovanadate.  This material is very rare as a gem!  Each is individually photographed. For calibrated stones see https://store.turtleshoard.com/products/lab-wakefieldite-loose-gems-aka-yttrium-orthovanadate-nd-yvo4-copy YVO4 is best known for its role in some very specialized lasers.  Like the more usual Nd:YAG it is a powerful lasing medium, but it has puts off a different wavelength and has other properties that make it preferable in some contexts.  Nanoparticles of medical-grade YVO4 have also shown promise as a treatment for wounds, promoting healing and reducing scar formation, and potentially even for general longevity, though the research is still in very early stages. As a gem it is a challenging cut, difficult to polish with a relatively low hardness of 5 (same as apatite and some glasses) and two directions of perfect cleavage.  However the reward for cutting it are exceptional optical properties (refractive in
