Barossa Stone - 42 - Professional Biab builder gel - 15ml
Sophisticated, earthy, and inspired by the ancient stone terraces of South Australia's legendary Barossa Valley wine region, this is a warm taupe-mauve with subtle shimmer that catches light like polished granite. Named for the heritage vineyards where generations of craftsmanship have defined Australian wine excellence, Barossa Stone captures the essence of refined tradition with contemporary elegance. The builder gel formula creates structure while the delicate shimmer adds dimensionality without ostentation.
Barossa Stone is the shade of someone who understands that luxury whispers. Wear it to wine tastings, professional dinners, gallery events, or any moment when understated sophistication proves your authority. The BIAB structure ensures nails stay strong through refined evenings and busy days alike, while the shimmer finish catches light beautifully in photography and conversation. This is professional elegance with depth.

How To Use
Start with clean, dry nails. Remove any existing gel, polish, or product completely using an appropriate remover.
Removes natural oils, dust, and any moisture — all of which cause lifting. Then apply nail bond or primer if needed.
Apply a thin, even layer of OPAL Gel Base Coat over the entire nail. Cure immediately under your LED lamp.
Using the OPAL Builder Gel brush, scoop a small bead, place it in the centre of the nail and allow it to self-level for 2–3 seconds before spreading. Cure under LED for 60 seconds.
Apply a second, slightly larger bead for your desired strength and length extension. Cure for 60 seconds.
Using a 100/180-grit Opal nail file, shape the free edge to your desired finish — square, oval, almond, coffin, or round. Work in one direction to prevent cracking.
If applying gel polish colour, apply a thin, even first coat and cure for 60 seconds. Follow with a second coat for full opacity and cure again.
Apply OPAL Gel Top Coat in a smooth, even layer over the entire nail surface. Cap the free edge to seal the product and prevent tip wear. Cure for 60 seconds.
Pro Tip
Allow each bead to self-level for 2–3 seconds before spreading. Work in thin, controlled layers — it’s easier to add thickness than to remove it. Always cap the free edge with your top coat to prevent tip wear.
