Glass velvet is the 2026 version of cat eye nails. The magnetic effect stays. The base underneath turns sheer, so the line of light sits inside the colour instead of on top of it.
Classic cat eye draws a bright streak across an opaque background. Glass velvet lets you see through to the nail, which softens the edges of that line and gives the whole nail more depth. It reads well on short nails and on natural nail shapes.
The difference in four lines
What glass velvet means
Two things happen at once. The colour or top coat is translucent, and a magnetic effect is drawn through it while the product is still wet. Once it cures, the line stays where the magnet put it.
Because the colour around it is see-through, the line has somewhere to sit. You get depth instead of a flat stripe. The name comes from how it photographs: light travels down the nail and gathers in one band, the way it does across a length of glass.
The fastest way in
A magnetic top coat goes over a colour you already own, which makes it the cheapest way to try the look. Semilac has two, and both are soak off and TPO free.
Semilac describes the T35 result as a glass nail and glazed nail effect, created with a magnetic wand rather than chrome powder. T36 does the same job with a holographic finish, so the line shifts through rainbow tones as the light moves.
Or put the effect in the colour
If you would rather have it built into the shade, four magnetic gel polishes cover silver, soft pink and raspberry.
Beyond those four, the shades with Gloss in the name are semi-transparent cat eye colours, which is the quality glass velvet depends on. 661 Linen Gloss through 665 Blueberry Gloss cover the pale end, 940 Taupe Gloss and 944 Glazed Cinnamon take it warmer, and 947 Basic Gloss is the sheer silver option.

The commercial case
One top coat, a cat eye version of every shade you stock
That is the argument for T35 and T36 over buying magnetic colours one at a time.
The finish changes with where the line sits, so agree the direction with the client before the first nail rather than after it.

Questions people ask about glass velvet nails
What are glass velvet nails?
A magnetic gel manicure on a see-through base. The magnet gathers the effect into a band of light, and because the colour around it is translucent, the band looks like it sits inside the nail rather than on the surface. It is the same magnetic principle as cat eye, applied to a sheer shade instead of an opaque one.
Is glass velvet the same as cat eye?
It uses the same magnetic principle. The difference is coverage. Cat eye is traditionally done on opaque colour, glass velvet on a sheer one, which is what softens the line and adds the depth.
Do I need chrome powder for a glass nail effect?
No. Semilac Top Coat Silver Gloss T35 is designed to give a glass and glazed effect using a magnetic wand instead, so there is no powder and no dust.
Does it work on short nails?
Yes, and it is one of the better options for them. A line running lengthways down a short nail gives the eye something to follow without adding visual bulk.
Can I do this at home?
Yes. The only part that takes practice is holding the magnet steady while the coat is still wet. Try it on one nail before committing to ten.
