Cristaux AB

FAQS

AB crystals are rhinestones with an iridescent coating over the top. This coating reflects the colours that surround it, so against pale surfaces it shines pinks, purples, yellows and golds, and against a darker background it shines blues, greens, yellows and deeper purples. For a more detailed explanation, read our guide to the difference between Clear and AB.

AB stands for Aurora Borealis, named after the Northern Lights. Swarovski developed the effect in 1956 in collaboration with Christian Dior, and it has been a staple of costume and couture ever since. The coating gives a single crystal all the colours of the rainbow.

If a rhinestone has a colour name with AB after it, the iridescent coating has been applied over the top. For example, Fuchsia is a hot pink offering that one shade of pink. Fuchsia AB is the same hot pink crystal with the AB coating over it, so it shines with different pink tones and gives the effect of more depth and sparkle.

Choose AB when you want movement, depth and sparkle, or when you cannot find an exact colour match to your fabric, because AB will complement almost anything. Choose a solid colour when you need the shade to stay true, for example matching a team colour, a dance school palette or a specific brand colour. Plenty of costumiers use both together, with solid stones for the colour and AB scattered through for the shift.

Yes, and that is the whole appeal. On pale fabric AB tends to read as pink, gold and soft lilac. On black or navy it pushes towards green, blue and deep purple. If you are working to a brief, order a small pack first and try it against your actual fabric under the lighting it will be seen in, because stage lighting changes AB dramatically.

Exactly the same way as any other rhinestone. Use the hotfix method with heat, the non hotfix method with a suitable adhesive, or stitch on sew on stones. Gem Tac is a popular choice for applying non hotfix AB crystals to fabric.

All sorts of embellishment projects, including performance costumes, dancewear, bridalwear, nail art, cardmaking, textiles and jewellery making. AB is one of the most popular finishes for embellishing because it works with every colour, gives a huge amount of sparkle and is available in almost every shape and size.
