Meaning
A white sparkle shape with a few points, set on a green square. It stands for sparkle or shine, presented more like a button than the loose star cluster of ✨.
People use it as a cheerful bullet point, to highlight something new or freshly cleaned, and for neat lists in green colour themes: “❇️ Room cleaned and ready for guests” If you want the magical, glittery mood, ✨ is the usual choice; ❇️ reads more like a label.
