Frequently Asked Questions

What is granite?

Granite is an igneous stone which consists of Quartz (35%), Feldspar (45%) and Potassium. There are many different quarries on every continent around the world and this gives the variety of colours. Much of the granite available today was formed about two million years ago. It typically measures 6 on the Hardness Scale of rock. Diamonds measure 10 on the same scale.

What is marble?

Marble is crystallised limestone, made up primarily of calcium and dolomite. It measures 3 on the hardness scale of rock. We don’t recommend marble for heavy wear areas such as kitchen bench tops.

What is Quartz?


Quartz (also known as engineered stone) is made from 91-95% natural quartz chips and fillers, with a 5-9% resin binder. These are combined together and “cast” and then cured to produce sheets of stone. Several different trading names are used, and the stone supplier will have detailed specifications of testing. The main advantage of engineered stone is that it has a more uniform look, especially in lighter colours.

How much will a stone bench top cost?

Material is priced on a per square metre rate and there can be a large variation in price between stone types, depending on colour and availability around the world. The fabrication costs include cutting, polishing, templating and installation. Therefore we treat every job individually and will quote specifically for your design or plan.

What colours are available?

Grace Stone Granite & Marble import and maintain a stock of 16 to 20 of the most popular colours in granite, and we also have access to major suppliers in New Zealand and overseas. If we don’t have the colour you want, we will source it for you. We also stock a range of Quantum Quartz and Caesar Stone, in 14 colours.

Where does your stone come from?

We choose the best quality granite from Italy, India and Brazil. Engineered stone comes mainly from Vietnam.

What about the edges?

There are a variety of edge types. The most popular and cost-effective are Square Edge and Pencil Arris. All showing edges are polished.

How long will it take to get my bench top?

Once your quote is confirmed, it will take between 10 and 15 days from templating and final measurements to installation.

Will the bench top scratch?

Under normal conditions, no. Granite and quartz are largely scratch resistant. However, diamond or tungsten implements can scratch the surface.

How do you clean the bench top?

You can use most household glass and surface cleaners. Granite can also be polished with aerosol polishes such as Pledge.

How thick is the stone?

Standard slabs are 20mm and 30mm thick. Not all types of stone are available in both 20mm and 30mm.

What is mitred?

This is when two pieces of stone are cut on an angle and joined together. Very thick edges can be achieved by laminating or mitre-laminating along the front edges of the bench top. In this way, drop-apron fronts of 40-200m deep bench edges can be achieved, giving the appearance of a much ticker block.

Is there a restriction on the size?

As a rule of thumb, granite slabs are 3 metres long by 1.8 metres wide. Quartz is 3 metres long by 1.4 metres wide. Anything bigger than this will require joining.

Where will the joins be located?

This depends on the slab size and the location of hobs, sinks and the design of your kitchen. We will attempt to place any join where it will have the least impact both aesthetically and functionally.

Will the join be noticeable?

Our joins are 1-2mm wide. They are filled with a matching coloured epoxy to make them unobtrusive.

Are there any defects in the stone?

Any defects that detract from the appearance or quality of the stone will be removed at cutting. However, being a natural product, slight occlusions and veins may occur on the stone. At times, slight colour variations can occur between batches and shipments. If you are concerned, you may call us and inspect your slab of stone before we start cutting it.

Are there any special requirements of the joinery beneath stone tops?

No. Standard kitchen joinery will support a stone bench top. However, special support is needed for overhangs of more than 35cm.

How does the process work if I want to order a stone bench top?

First, you can either visit our showroom at 61 Williams Street, Kaiapoi, or send in your plan by fax or email for an obligation-free quote. Once you are satisfied with the details of your quote and design, you will need to sign a specification sheet and return it to us. You can also specify an expected delivery date. We then schedule your project for production at our Kaiapoi factory. The next step is to make a template of your new bench top, make it and install it!
