How to say "sparkling" in Japanese

• キラキラCommon
  adverb (with と), suru verbCovers bright, continuous sparkling and glittering: light on water or jewelry, twinkling stars, eyes sparkling with excitement. This is the mimetic word for steady, eye-catching sparkle.
  星ほしが空そらにきらきら輝かがやいている。↗

  The stars are twinkling in the sky.
• ちらちらCommon
  adverb (with と), suru verbReally describes flickering or glimmering — light appearing and disappearing intermittently. As 'sparkling' it suits only faint, on-and-off glints; for bright, steady sparkle it is seldom the word you want.

Choose 「キラキラ」 for bright, continuous sparkling — glittering surfaces, twinkling stars, sparkling eyes; reserve 「ちらちら」 for faint, intermittent glinting, since its core sense is flickering or glimmering on and off rather than steady brilliance.
