Serinity rhinestones non hotfix Round (2000, 2058 & 2088) in Sapphire AB are flat back crystals that can easily be applied to most surfaces with glue. Sapphire AB is a deep and rich shade of blue that is named after the precious gemstone of the same name. It is a sophisticated and elegant colour that is associated with wisdom, loyalty, and truth. Sapphire AB can vary in shade, ranging from a deep, dark navy blue to a brighter, more vivid hue. It has a calming and soothing quality that makes it a popular choice in costume design, fashion, and other creative applications. Sapphire AB is often used to create a sense of tranquillity and serenity, or to add a touch of sophistication and refinement to a design. The AB (Aurora Borealis) effect is an iridescent coating that covers the top of the crystal, making it shimmer like a rainbow. The base colour of the crystal can still be seen underneath but there is a noticeable pink and blue shine to it as it hits the light.

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