You can buy coralina stone pretty much all around the country. It’s mined here in the country.
The price depends on distance of sales point from distributor. It’s heavy and the farthest the distance, the higher the transportation cost will play in how much you pay by Sf just to buy it, without delivery fee accounted for.
I don’t mean the transportation cost from where you buy it from to your house, but the cost of goods for the retailer to source them in the first place.
Also, the amount of material Sf you purchase will play a part on the sales price.
There are some color differences on coralina. A lighter and darker shade.
Also some specialties with unique patterns and coloring.
If using for a pool deck, use the thicker bricks.
If just a patio deck covering, you can go with the 2cm tiles.
Place is called Marmotech design center.
But like I explained, you can buy from other sources -maybe cheaper- all over the country.
