The Gemini Guarantee

Warranties

A guarantee with four generations behind it.

Gemini Worktops' guarantees are supported by four generations of stone expertise and an established national business with more than 100,000 installations behind it. Every Minerox® and Stonelore® worktop we make and fit is covered as standard.

Our promise

One level of cover, for the full term

Your warranty comes from us directly, the people who chose the stone, cut it and fitted it.

Every Minerox® and Stonelore® worktop comes with two warranties as standard. The 25-year material warranty covers the stone itself. The 5-year installation guarantee covers how we cut, finish, join and fix it in your kitchen.

Cover begins on the day our installer confirms your worktop is fitted, once your order is paid in full. There is nothing to register and no forms to return. The level of cover stays the same for all 25 years, rather than reducing over time, and where we replace a section we will also replace adjoining sections if a reasonable match can't be achieved.

Nothing to register

Cover starts automatically from your installation date.

No middlemen

Claims come straight to us, never passed to a third-party supplier.

Moves with your home

Both warranties transfer to the next owner for the time remaining.

Keep your invoice

It's your proof of purchase. We need it, or other proof, to accept a claim.

Care & warranty guides

Choose your range

Each range has its own care and warranty guide. The care guidelines form part of your warranty, so keep the guide with your invoice.

Care in brief

Look after it, and it will look after you

Quartz is low maintenance and never needs sealing. A few simple habits keep it looking its best, and they form part of your warranty.

Every day

A damp cloth and a little worksurface cleaner. Rinse, dry, and buff with a white microfibre cloth.

Spills

Wipe up tea, coffee, wine, oils and sauces straight away. Fresh spills lift far more easily than dried ones.

Stubborn marks

Bar Keepers Friend cream cleaner with a non-abrasive white sponge. Never scouring pads or multi-surface polish.

Heat

Quartz is heat resistant, not heat proof. Always use a trivet under hot pans.

Heavy and sharp

Always use a chopping board, and don't stand, sit or place very heavy items on the worktop.

Chemicals

Avoid stripping agents, grease removers, caustic soda and anything above pH 10.

A complimentary care kit is provided at installation. Care kits aren't available to order, so for ongoing cleaning we recommend Bar Keepers Friend cream cleaner. The full guidelines are in your range's care and warranty guide.

How to claim

Making a claim

If you think your worktop has a defect, contact our customer service team as soon as you notice it.

  1. Send your name, installation address and invoice or order number.
  2. Tell us briefly what the problem is and when you first noticed it. Photographs help.
  3. We verify the claim. If a covered defect has occurred, we repair or replace the affected sections, or re-perform the work.

Good to know

What isn't covered

  • Commercial use, or use other than as a residential kitchen worktop.
  • Minor blemishes not reasonably visible from more than 1 metre away.
  • Taps, sinks and other items that aren't the worktop.
  • Damage from direct heat, impact, excessive weight, unrecommended chemicals or prolonged direct sunlight.
  • Fair wear and tear, neglect or improper use.
  • Movement of base units, or work by anyone other than Gemini Worktops.
Natural characteristics, not defects

Dark spots. Small clusters of darker spots are inherent to engineered stone and within industry tolerances.

Light. All worktops refract light, so some areas can look duller or shadowed in certain lighting.

Mirror chips. Where cutting dislodges a mirror chip, we fill the spot with resin so the surface is even and smooth.

Transferring your warranty

If you sell your home, both warranties pass to the new owner for the time remaining. They'll need reasonable evidence that they own the property, and a letter (or chain of letters) from previous owners passing on the benefit. We'll happily supply a specimen letter.

Our warranties are in addition to your statutory rights, and don't replace them.
