Serinity Flatback Crystals

A Bluestreak Crystals Brand

Serinity is a brand built by Bluestreak Crystals, launched in direct response to the industry's need for a premium, unrestricted alternative to Swarovski following changes to Swarovski's distribution model.

What Are Serinity Flatback Crystals?

Faceted in Austria using the same cutting infrastructure as the world's leading crystal brands, each Serinity flatback features platinum foiling on the reverse to amplify colour depth and light refraction, and is produced to consistent sizing and colour standards across every batch. The range covers sizes SS3 to SS48, spans three precision-cut designs and is available in over 150 colours, effects and finishes, all lead-free and EU REACH-compliant.

Are Serinity Flatbacks as Good as Swarovski?

Serinity flatback crystals use the same article reference codes and SS sizing system as Swarovski, so sizes, shapes and product types translate directly with no need to redesign patterns or templates. Manufactured in Austria to matching technical specifications for faceting, foiling and light refraction, Serinity flatbacks are comparable to Swarovski in brilliance and consistency, at around 10% lower prices and with no restricted purchasing process.

Hotfix, Non-Hotfix and Sew-On: Which Type Do You Need?

The Serinity flatback range includes three application types, each suited to different materials and techniques. Choosing the right type before ordering avoids adhesion problems and rework.

• Hotfix flatbacks — pre-coated with a heat-activated adhesive for fast, secure application to fabrics and textiles using a hotfix applicator wand, heat press or iron (steam off). Also known as heat-set or iron-on crystals. Ideal for dancewear, costumes, bridal embellishment and fashion garments.
• Non-hotfix flatbacks — no pre-applied adhesive; bonded using a one- or two-component jewellery glue or specialist adhesive. The most versatile option, suitable for glass, metal, plastic, leather, fabric and mixed-media surfaces. Widely used for nail art, glue-on crystal work and accessories.
• Sew-on crystals — pre-drilled for hand-sewing or machine-stitching directly onto garments and textiles, ideal where adhesive alone may not provide sufficient holding strength for high-movement designs.

Crystal Cuts: 2000, 2058 and 2088 Explained

Serinity flatback rhinestones are available in three cut designs, each engineered to maximise light refraction at their respective size ranges.

• 2000 Rose Cut — 8 facets, available in SS3 and SS4. A clean, classic cut ideal for fine detail work, micro-embellishment and nail art.
• 2058 Xilion Rose Cut — 14 alternating facets, used for SS5 to SS10. Optimised for maximum light capture in smaller stone sizes, popular for intricate nail art and close-detail embellishment.
• 2088 Xirius Rose Cut — 16 facets in a patented starburst arrangement, used for SS12 to SS48. The most brilliant cut in the range, delivering Swarovski-matching light refraction for high-impact fashion embellishment, stage costumes and bridal couture.

Available Sizes: SS3 to SS48

Serinity flatback crystals are sized using the SS (Stone Size) system, covering SS3 (approximately 1.3mm) through to SS48 (approximately 11mm), from ultra-fine micro crystals for nail art to large focal stones for statement embellishment.
