Spalling of this is super common around shower floors and next to doors and windows, where there is moisture wicking into the slab. If you fill with polyester it will pop out so do not guarantee it. If there are voids you can use an acrylic grout and sand it in with a dry pad, 220, then 400 which will leave a nice hone, hit gently with a 10" 80 grit Tynex brush (careful not to dig out fill) on a hand machine to get back that sparkly look finish and blend into the floor. The acrylic grout can breathe and will not look as good but it will last a lot longer.

Jerusalem gold limestone is a sedimentary stone comprised of marine organisms,(plant and animal)
It contains skeletal remains, shells, fossils, pits and fissures.
Its full of calcite and can have issues in wet environments.
The stone is filled when processed at origin use polyester resins
Your picture only shows an open fissure or so on one tile.
The face of the tile appears in good shape as do the grout lines.
I see no signs of moisture or any spalling.
I would think that there would be some more open fissures to deal with on this floor.(this is a floor?)
It seems as John mentioned "the Nature of this particular stone"
You will fill these voids with a matching polyester resin (overfilled) and then make them flush to the surface of the stone.
The surface should then be refinished to a uniform honed finish and sealed.

Michelle,

 

What you are seeing are areas in the stone where the veins are opening up. This is not uncommon in some of these types of stone. This could be caused by the cleaning practices, polishing practices and just the natural of the stone.

Jerusalem gold antique limestone honed. Does anyone know what could cause this "peeling"?
