CONT

Le chatoiement est un phénomène propre à certaines pierres à texture fibreuse qui réfléchissent la lumière d'une façon particulière.

CONT

La chatoyance ne se retrouve que dans les pierres en cabochon [...] le phénomène, qui est dû à la façon dont la lumière est réfléchie par de minuscules inclusions cristallines parallèles, se présente comme une ligne semblable à la pupille contractée d'un œil de chat.
