What Is the Difference Between Hotfix, Non Hotfix and Sew-On Crystals?

Swarovski flatback rhinestones are available in three application types, each suited to different materials and techniques:

Hotfix flatbacks — pre-coated with a heat-activated adhesive. Apply using a hotfix applicator wand, heat press or iron (steam setting off). The standard choice for fabrics, garments, dancewear, costumes and bridal embellishment. Also sold as iron-on crystals.
Non hotfix flatbacks — no pre-applied adhesive; bond using a one- or two-component jewellery adhesive or specialist crystal glue. Compatible with glass, metal, plastic, leather and fabric — the preferred choice for accessories, nail art and mixed-media work.
Sew-on stones — pre-drilled with holes for hand-sewing or machine-stitching directly onto garments and textiles. Recommended wherever adhesive alone may not provide sufficient hold over time.

What Sizes Do Swarovski Flatback Crystals Come In?

Swarovski flatbacks use the SS (Stone Size) system, running from SS3 through to SS48:

SS3 — 1.3mm — nail art, micro-detail work
SS4 — 1.5mm — nail art, ultra-fine embellishment
SS5 — 1.7mm — nail art, fine textile work
SS6 — 2.0mm — delicate garment and accessory embellishment

SS16 — 4.0mm — fashion embellishment, dancewear
SS20 — 4.7mm — bridal wear, statement embellishment
SS30 — 6.4mm — focal stones, bags and accessories

How Swarovski Flatback Crystals Are Cut: 2000, 2058 Xilion and 2088 Xirius

Each Swarovski flatback cut is engineered to maximise light refraction at the sizes it covers:

2000 Rose Cut — 8 facets, available in SS3 and SS4. A clean, classic cut for fine detail work and micro-embellishment.
2058 Xilion Rose Cut — 14 alternating facets, used from SS5 to SS10. The Xilion geometry is specifically optimised to maximise brilliance in smaller stones.
2088 Xirius Rose Cut — 16 facets in a patented starburst arrangement, used from SS12 to SS48. Named after Sirius, the brightest star visible in the night sky, the Xirius cut delivers the highest brilliance of any flatback crystal on the market.

Frequently Asked Questions

What is the difference between Swarovski hotfix and non hotfix flatback crystals? ▾

Swarovski hotfix flatback crystals have a heat-activated adhesive pre-applied to the reverse, allowing them to be bonded to most fabrics and textiles using a hotfix applicator, heat press or iron (steam off), also called iron-on crystals. Non hotfix flatback crystals have no pre-applied adhesive and are bonded using jewellery glue or two-component adhesive, making them suitable for a wider range of surfaces including metal, glass, leather and plastic.

Do I need to apply to buy Swarovski flatback crystals? ▾

Yes. Swarovski restricts the purchase of flatback crystals and rhinestones to approved brands, businesses and professionals. You can complete our online application to request access. Once approved, you can purchase the full range of Swarovski hotfix, non hotfix and sew-on crystals directly through our online store.

What are the Swarovski flatback crystal sizes (SS sizes)? ▾

Swarovski flatback crystals are measured using SS (Stone Size) numbers. Common sizes include SS3 (1.3mm), SS5 (1.8mm), SS10 (2.8mm), SS12 (3.2mm), SS16 (4.0mm), SS20 (4.7mm), SS30 (6.4mm) and SS48 (approx. 11mm). Smaller sizes (SS3–SS10) suit nail art and fine detail work; mid-sizes (SS12–SS20) are the most popular for general embellishment; larger sizes (SS30+) are used for statement and focal embellishment.

What is the difference between the Swarovski 2058 Xilion and 2088 Xirius flatback cuts? ▾

The 2058 Xilion Rose features 14 alternating facets and is used for smaller sizes (SS5–SS10), optimised for maximum brilliance at a small surface area. The 2088 Xirius Rose features 16 facets in a patented starburst arrangement and is used for larger sizes (SS12–SS48), named after Sirius, the brightest star in the galaxy, and engineered to produce the highest possible light refraction of any flatback crystal in the world. For the very smallest sizes (SS3–SS4), the 2000 Rose Cut with 8 facets is used. At SS12 and above, the 2088 Xirius is always the cut to choose for maximum sparkle.

What glue should I use for Swarovski non hotfix flatback crystals? ▾

For fabric applications, a fabric-safe adhesive such as Gem-Tac is recommended, holding well through repeated washing. For hard surfaces such as glass, metal or plastic, E6000 or a two-component epoxy adhesive provides the strongest, longest-lasting bond. For nail art, a specialist nail crystal glue is recommended. Browse our full range of adhesives and application tools to find the right product for your surface and technique.

What if I don't qualify for Swarovski? Are there alternatives? ▾

Yes. Serinity flatback crystals are manufactured in Austria to equivalent standards, with the same Xilion/Xirius Rose-style starburst cut and platinum foiling, available to buy immediately with no approval required, at approximately 20–30% below Swarovski pricing. Preciosa MAXIMA flatback crystals are a high-quality Czech-made alternative, also unrestricted. Both use the same SS sizing system as Swarovski for easy transition.

Are Swarovski flatback crystals lead-free? ▾

Yes. All Swarovski crystals manufactured since 2012 are fully lead-free and REACH-compliant, certified to Oekotex Standard 100 and ISO 9001, making them safe for use in professional production and consumer goods worldwide.
