The Story
The inside
of a shell
Nacre is not a pigment, it is an architecture — layers thinner than the wavelength of light, stacked so that colour appears only where the light bends. Mixed into a lacquer it dies, because a mixed pearl points every direction at once and therefore none. So the atelier stopped mixing it. On Ivory Sheen the nacre is floated in a single direction beneath the glaze, drawn from cuticle to free edge, and the sheen it makes is a band that travels when the hand turns rather than a shine that sits still.
The dust is the second decision. One glitter grade reads as a craft supply; three read as light. Gold for warmth against the skin, silver for the cold edge that keeps ivory from turning yellow, and clear for the flashes with no colour at all — scattered by hand, never poured, so no two tips catch alike. The set is cut in two lengths because the same band of light behaves differently across a shorter nail than a longer one: medium keeps the sheen close and discreet, long lets it run the whole tip.
Not a colour — a direction the light agrees to travel.
