Comment: Cold, hard and not easy to understand (but to know him is to love him). This mix of blue and green is a rare but classic color in sapphire. It needs time and light to penetrate in all its beauty (which always is a sign of a great gem). Inclusions visible (one that is) only under the lens. The main picture shows the maximum color and brilliancy on a sunny day (without direct sunlight) and indoors. It is difficult to say if it is more green or blue then, perhaps just equal. Challenging! Character stone for a men's ring. With MD80 this gem is as dark as Kashmir blue - not expect a shiny bright gem. Perfect dimensions, great proportions. These Tanzanian sapphire usually are usually found in smaller sizes only, around one carat, so three carat is fat.
