The photos form part of the description. Like all colored stones there is a color variation that occurs in different lighting conditions both inside but also outside, even the time of day can make the color of a stone appear a little different. We do our best to show colors as we see them. Color perception is highly individual and some people can perceive more colors than others, also colors can appear somewhat different on different screens and devices due to variations in screen hardware and device display settings.
Comment:
Unfortunately, in the last two decades many sapphires seen in modern jewelry have had the color induced by high temperature heating in chemicals such as beryllium. This is called diffusion treatment and includes surface diffusion, bulk diffusion, lattice diffusion, deep diffusion and beryllium treatment. In recent years sapphires have been clarity enhanced by filling any fissures or cracks with molten lead glass, sometimes the glass is colored as well, with time the filler falls out or goes cloudy ruining the stone. Polymer resins can be used in a similar way. Colored coatings can be applied to the back of a sapphire. These treatments are undesirable and such treated stones are of very low value. We do not sell sapphires with these treatments. The stunning midnight blue natural sapphires in this special vintage bracelet are unheated and untreated just as mother nature made them making this bracelet a perfect choice for an engagement, wedding or anniversary celebration to be handed down in your family for generations to come.
