UNDERSTANDING COLOR-SHIFT SAPPHIRE
Sapphire belongs to the corundum mineral family, with the chemical composition Al₂O₃ and a Mohs hardness of 9. Certain natural sapphires display different colors under daylight-equivalent and incandescent illumination because their absorption of visible light varies with the light source.
This behavior is described as color shift or color change, depending on the strength and distinction of the observed colors.
RAKWANA ORIGIN AND GEOMETRIC CUT
The origin is Rakwana, a gemstone-producing area in Sri Lanka’s Ratnapura District. Sri Lanka, historically known as Ceylon, is recognized internationally for its natural sapphires and longstanding lapidary traditions.
The gemstone’s fancy geometric outline gives it an unconventional appearance compared with traditional oval or cushion cuts. Its angular facets and relatively compact dimensions offer possibilities for custom rings, pendants, collector settings, and individually designed jewelry.
