Serinity rhinestones non hotfix Round (2000, 2058 & 2088) in Jonquil AB are flat back crystals that can easily be applied to most surfaces with glue. Jonquil AB is a light and warm shade of yellow, often described as a pale or soft yellow. The colour is named after the Jonquil flower, which is a type of narcissus plant that produces fragrant yellow flowers. Jonquil AB is a cheerful and sunny colour that is often associated with happiness, optimism, and warmth. It is a popular choice in fashion and jewellery design for its ability to add a bright and cheerful touch to any 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).
