It all depends on how the pictures are to be used.  How will they be
printed, and how big?

MF lets you use faster film for a given grain size, and will give shallower
DoF which may or may not be an advantage.  If all else is equal, MF will let
you make a bigger enlargement - which may or may not matter, depending upon
intended use of the image - and will give you finer gradation of tone in the
image - which may or may not matter, depending on whether the printing
process is capable of representing that subtlety.

You can do this with 35 mm, with the right equipment.
Gear that may be useful:

1. macro lenses
2. extension tubes and/or rack & pinion
bellows tube.
3. diopter lenses (to attach to existing lenses)

Here as elsewhere you may need to make
exposure corrections for bellows extension
and/or reciprocity failure.

It depends on the size of the final image in the brochure, and the
desired quality of image.  You need no less than 300 dpi for decent
print quality, so a D100 should be fine for an 7 x 10 inch printed
image (providing you don't crop too much).

You will need some sort of close-up capability:  macro lens, extension
tubes, or bellows.  To be able to control the lighting, you will need
space between the camera and the subject, so a longer than normal lens
is in order for small objects.

Producing a technically correct image is only the beginning.  The
greatest challenge will be producing an attractive image through
lighting, arrangement, and set design.

Do a search for "photography" in the library.

Good luck.

The camera will do what you want. You need a good macro lens (the 60mm Nikon
is perfect.) 6MP is plenty for 1:1 shots of jewellery. You've said you have
the "lights, etc.", assuming you know what you're doing you shouldn't have
any problems.

When you say One to One, do you mean that the image must be life size at the
camera?  Or do you mean that it will be reproduced in print at life size?
The Nikon D100 is not a 35mm camera.  Its format size is about 18mmx24mm
while the 35mm camera's format is 24mmx36mm.  These details in format sizes
might be important if the image must be life size at the camera.  What is
the actual size of the jewelry pieces?  If shot at life size, will the
images of the jewelry actually fit within the camera's format.  Of course,
if shot digitally, the actual image size can be easily changed to life size
in PS, etc if the jewelry is larger than the camera format and therefore
must be shot at smaller than 1:1 at the camera.  What resolution is required
in the final image file if it is shot digitally?  If the jewelry pieces are
too large to physically fit at 1:1 magnification within the small format
size of the D100, at what magnification would they have to be shot at to
make them fit in the 18x24mm format?  Could they then be resized to 1:1 and
still maintain adequate resolution for reproduction?  Answer these
questions, and you will know if you can do the shoot with the D100.

That would depend on how large the earrings and bracelets are. 1:1 leaves
very little room for guess work. Reproduction ratio in a brochure also
leaves very little room for guesswork. Unless you consider that a
contradiction of 1:1. Shoot what you brung; it doesn't sound at all
challenging.
