Water ring
A faint ring left behind after a glass or bottle sits on the surface.
How to spot it
- Faint circular outline matching a glass or bottle base
- Sometimes lighter (etch ring), sometimes darker (mineral residue)
- Often appears in clusters where drinks were left
Often confused with
Etch
If the ring is dull and lighter, it is technically a light etch.
Sealer flaw
Sealer rings are usually larger and more uniform across an area.
What causes it
Hard water minerals or trace acid in beverages dwelling on the stone.

Do NOT use on this damage
Vinegar to descale
Acid eats into calcium-based stone and creates a real etch.
Lime/scale removers
Most are acidic and made for ceramic, not stone.
Prevent it next time
- Use coasters — every drink, every time.
- Reseal annually so water beads instead of soaking in.
- Dry the area after spills and condensation.
Always test any product on a small, hidden area first. Cost ranges are general estimates and vary by region and stone.
