According to fishcakes :
Hello - We got about a quarter inch round chip in our Uba Tuba Granite
when a glass salt shaker fell from the top cabinet. Does anyone have
any suggestions or home remedies that the do it yourselfer could try
to fill the chip. I noticed there may be some professional granite
fill products, but they seem complicated. I'm not too worried about
an exact color match, just looking for something to fill the hole as
it is unfortunately in a very noticeable section of the counter. I
was thinking like clear silicon, but then thought that may not stick
to it or be good for a food prep area. What is generally done about
chips of this size, or is the answer simply leave it alone and live
with it.

Probably the best "amateur" fix for this would be to use epoxy, mixed
with small amounts of dye/color (eg: artist dye powders) to make it less
glaringly obvious. 5 minute epoxy would do, but it'd be better to
use one of the longer open time formulations that's not nearly
as thick. The West Systems sample kit (around $10 at marine supply,
canoe builder supply, many woodworking hobby stores etc) probably has
enough material to do the job.

If you use something thick, you'll need to force it level (eg:
wax paper under a wooden block) and squeeze out will be a PITA.
West will self-level. If you end up having to sand it, you'll
have to polish the result to get some gloss back.

After a day or two, the repair will be almost as hard as the rest
of the countertop. Silicone is just too soft.
