    Try these sites 

    http://www.barrancadiamond.com/lap/bld_303_con.html 
    and 
    http://www.ukam.com/diamond_tile_blades.htm 

    I have 2 blades I really like, a Barranca BD 303 in .025 kerf and the
    Ukam in .032 were I to pick a favorite, it would probably be the Ukam.
    

    The Barranca I use with oil lube, it was the recommendation of the
    store I bought it at. 

    On the Ukam, they recommended a water based lubricant and a light
    feed. They have a lot of information on their site that is well worth
    the time reading. 

    Depending on the size of your saw, both of the above would provide
    very good service for the rock you plan on opening. If you have a
    larger saw, like a 10 to 14 inch and do boulders :-) I am trying the
    Harbor Freight blade, specifically the 10" Tile saw blade, it has a
    much faster turning speed than normal ( like 3 times), be prepared to
    force feed lubricant to it at its full rated speed and use a light
    feed rate of 2 to 3 pounds. I have only had it in service since
    November so I am not sure how well it will last yet, but at the price
    it was worth the try and so far the cutting has gone very well on
    some pretty hard material. 

    The only blades I have found that I am totally dissatisfied with no
    matter the manufacturer, lubricant or feed rate are the blades with
    the little steps around the rim.
