What Are Serinity Hotfix Crystals?

Serinity Flatback Crystals (also known as rhinestones) are lead free, laser-cut glass crystals with a faceted front designed to catch the light and a flat side that is designed to sit flush on a flat surface, perfect for rhinestone embellishment.

Serinity Hotfix Crystals can come in a variety of finishes, the most used option is foiled crystals (F) that have a silver foiling on the back just like standard glass mirrors. This backing helps reflect the light up through the coloured glass of the crystal, enabling the colour to pop to its fullest dazzling effect.

When a crystal is unfoiled (UF) it has no foiling on the back, therefore you can see through the crystal, this often results in a more delicate twinkle of colour. Another style is the lacquered effect, which has a boldly pigmented lacquered backing that gives a truly solid pop of colour and all sparkle results from the cut of crystal and not any foiled affect.

Round Hotfix Crystals

Round flatback crystals are measured differently to other shapes of crystal, which follow the usual rule of ‘length x width’ in mm. You will notice round cut crystals are classified with SS numbers like SS5 or SS20, “SS” means “stone size”. On our product pages we have converted these numbers into mm measurements that cover the diameter of the crystals circular surface area.

Round flatback crystals also come in a few different facetted designs (2000, 2058 and 2088) which are determined by the size of the crystal because the larger crystals have more space on them to allow for extra facets. The most famous design is the Xillion Rose Cut that can be found in SS12 – SS48 and boasts an iconic starburst appearance. The other easily recognizable cut is the Chaton Rose which is a simpler but still stunning design.

Both Xillion and Chaton Rose contain ‘Rose’ in the name because they are circular designs. This type of “Rose” refers to the cut of the crystal, not the colour, the colour of the glass will be specified separately on the wholesale pack.
