noun
facet; faceted object

Edo-style cut glass has beautiful fine facets.

カットグラス is a loanword for cut glass in general, while 切り子 specifically refers to the traditional Japanese faceting technique and objects.
Compound of 切り (kiri, 'cutting') + 子 (ko, diminutive suffix), literally 'little cut thing'. The exact historical derivation is uncertain, but the term has long been associated with faceted glassware.
