Hi - I am so sorry but I don't think they are available any longer. I do not remember the name( it was 4 years ago) but I did try and obtain it again for another job and was told it was no longer available. Depending on your location you can take the photo to your local stone yard and perhaps they can do a search for you. Blue is the most difficult quality in a stone to find. Good luck!
