Miss Potton turned red and pale and pink, and blotchy combinations of all three, and finally settled on the mousseline de soie, for which Lydia then bought a pair of white satin slippers, kid gloves, and a thin gold chain with a pendant of rose quartz and earrings to match.

Quartz and rock crystal, suffused with Plattnerite, glimmered about the framework, giving the whole a sense of unreality and skewness.
