Have you ever heard of a pocta diamond or gemstone?
Unlike ordinary pear-shaped gemstones, this octagon + pear-shaped diamond has been cut with great engineering skill, so there is little to no window in the gemstone!
Pear-shaped gemstones have a commonly found effect known as the bow-tie effect where light is not reflected but is absorbed by the diamond, thus forming dark patches in the diamond like the shape of a bow. These dark patches are a cause of value depreciation; therefore, gem cutters need to ensure minimal bow-tie effect.
This beautiful no heat pinks sapphire has been sourced from South Africa is definitely an engineering perfection!
