The slightly included clarity gives the gem personality and veracity, a humanizing detail that will feel familiar to a descendant who inherits the piece generations hence. Properly set and cared for with periodic professional cleaning and inspections, the stone will require no special tempering or treatment to maintain its presence. Its Tanzanian origin lends an additional layer of story to hand down, the memory of a place and of the earth that produced a color so intense it can make a room feel quieter and a moment feel more significant.
