No wonder the saying 'slower than molasses in January' is so true. You ever try and pour cold molasses? When I think January, I think cold, then I think garnets!
Garnet is January's birthstone as we all know, but did you know that garnets come in a range of colors? Here are examples of some. I found examples of all of these different garnets online. Click on the picture and it will take you to the site for more gemstone information.
Almandine - Deep, dark, rich red to purplish red to orange red (probably the most common)

Demantoid - Medium green to slightly yellowish green

Hessonite - Brilliant yellow to yellowish brown (one of my favorites)

Pyrope - Deep, dark, rich red to slightly purple red

Rhodolite - Shades of pink through reddish lavender (absolutely stunning)

Spessartite - Medium orange to reddish orange (sometimes called mandarin garnet and makes me stupid happy)

Tsavorite - Medium, intense green to slightly yellowish green (now ya know why emeralds are the alternate birthstone for January)

Uvarovite - Bright green (most of the examples I found for this garnet were all druzy's)

Now I know you are all wondering "Where can I get garnets?"
