"We purchased a bulk bag of 'black ice' containing 2 different coloured stones, black basalt and blue ice. We have previously used this product, although from a different supplier, to cover our front garden and the product from the Stone and Garden Company is only vaguely similar. You would think that 2 different stone types mean a 50/50 mix, which is certainly what our 3 previous bulk bags have been, but the product from Stone and Garden Company contains a majority of black basalt so looks nothing near to what we have previously used. When the delivery came I initially sent it back as it looked like a whole bag of black basalt. I had to wait several days for the pictures to be sent showing that it was indeed 'black ice'. This caused me having to pay a redelivery charge of £18 for a product that I am not completely satisfied with. We have had a small area done now for a month and a half, as well as the open bag being left on our driveway but despite all the rain that we have had ,the 'dust' that the company said was the cause of it looking the way it did has remained. Please see the photos that accompany this review; the first one is a screen grab from their website, the second is the bulk bag not long after it had rained and the third photo is the small area we have done showing the older product to the front of the photo and the product from the Stone and Garden Company in the background. THINK TWICE BEFORE ORDERING BLACK ICE FROM THIS COMPANY."
