Serinity rhinestones non hotfix Round (2000 Rose, 2058 Xilion & 2088 Xirius) in Cool Blue are flat back crystals that can easily be applied to most surfaces with glue. Cool Blue is a versatile colour that can be used in various design contexts to create a feeling of openness, purity, and a modern, airy aesthetic. This colour is characterised by its light and crisp appearance, reminiscent of a clear sky or the surface of icy glaciers. Cool Blue typically has a subtle hint of blue, sometimes with a touch of grey or silver, creating a clean and calming effect.

Serinity flat back crystals are available in three types of cut: 2000 Rose Cut with 8 facets (SS3 and SS4); 2058 Xilion Rose Cut with 14 facets that optimises the light reflection of smaller sized crystals (SS5 to SS10); and 2088 Xirius Rose Cut with 16 facets and a unique star cut design which provides the ultimate brilliance (SS12 to SS48).
