This borders on ostentatious. Like true tanzanite, it is not purple and not blue. It is also not Tanzanite. It may be set in silver, that much may be true, though anyone can stamp metal 925 and plate it. True tanzanite shows colors of rose and blue in purple. I've owned it. This stone is almost royal blue. It's pretty enough,  nicely shaped, the ring is comfortably sized. For that it gets an OK rating. For truth in advertising, it flunks.
