Spatial Note
An unheated sapphire of this saturation and size is presented perhaps once a year. Held to morning daylight, the silk reveals itself in the table.
A rare padparadscha sapphire holding the lotus balance between pink and orange. Under daylight the warmer tones lead. Under incandescent the pink turns intimate. The colour reveals more as you look at it longer.
A blue sapphire of cornflower saturation with the fine silk that gives the colour its characteristic depth. The clarity is exceptional. Selected at source for the evenness of saturation across the table.
A chrysoberyl that shifts from green in daylight to red under incandescent light. The colour-change is among the rarest phenomena in gemmology, native to fewer than a handful of gem species. A collector's piece in the strict sense.
