Kevin,
Geminal diols >C(OH)2 are very rarely stable enough to put them onto the table in pure crystalline form. An example is 
chloralhydrate CCl3-CH(OH)2 or the reagent ninhydrine. They are stable only if strong electron attracting groups are 
attached to the carbon atom. However, in aqueous solution they can exist in equilibrium form with the corresponding 
keton or aldehyde.
