Sapphire Gemstone come in different colours.
Sapphire Gemstone Value
Colour is the most important element in estimating the value of sapphire. Hue counts, the closer to a pure blue the better, but saturation is more important.
Top sapphires reach vivid saturation. (Many of the gems on the market are actually grayish). Tone is also an important consideration.
Dark sapphires are abundant and never reach very high values. (Of course, the same can be said for all dark gems. Too dark and they will only be moderately valuable). The pictures below are a rough illustration of differences in saturation.
Few gems have held our attention over millennia as well as sapphire. The pure blue colours and excellent durability of this gem-quality member of the corundum family make for an exceptional gemstone.
Sapphire come in all colours of the rainbow.
However, not all sapphires are blue. They come in every colour of the rainbow. Except red. All red corundum gems are considered Rubies.
Blue sapphires are simply called sapphires. Sapphires of other colours are named yellow sapphire, pink sapphire, etc. Sapphires get their extraordinary colours from traces of iron, titanium, chromium, and other elements.
