Hi, I m supposed to receive Lab-Craeted Sapphires, but what I ve received is pure blue glass imitating as sapphires. Sapphires has the quality to be very cold stones regardless of the surroundings, while glass is picking up the temperature of the surroundings. Your stones are not cold, but room temperature and not even cooling down, which indicates that what I ve received is blue glass. Please give me a full refund. Best regards, Istvan
