Below is a comparison of just a couple of the shades (Earthly Harmony and Jade Dragon). I did not swatch the rest of the collection, but more photos can be found at All Lacquered Up.
Have a good weekend all!
There is a significant difference between Particuliere and Earthly Harmony. Earthly Harmony is more grey toned and has flecks of gold shimmer (which show up when photographed with a flash but are sadly not really noticeable on the nails), and has more of a dull finish. Obviously, Particuliere is a lot darker, with more brownish-taupe tones and has a smoother finish.
Sorry, I misspelled Lippmann in my labels! (left out an the "n" at the end)
Deborah Lippmann's Don't Tell Mama is darker (it almost appears black in some lighting) and looks to have teal green shimmer, whereas MAC's Jade Dragon has more of a forest green base, with pretty dark greenish-blue glitter. If you are a fan of dark polish you may love these! (I don't own the Lippmann shade--just tried it on in Nordstrom today.) Be forewarned: the glitter/shimmer in these is not really apparent once you've had them on for a while. It is the kind of shimmer that shows up only under direct lighting and at certain angles. This may be a plus or minus depending on your level of love for shimmer! (I just happened to be trying on SOPI's Run With It earlier today at Sephora, so that one is just randomly included with the others :).
