Matte: As you'd expect, matte shades have a dull finish, without any shimmer or sparkle.
Pearl: Another fairly standard term, these shades have a satiny to slightly shimmery frost finish, but are devoid of separate particles of glitter.
DS: Stands for Double Sparkle, these are satin (semi-matte) based shades with an added dose of fine glitter, though most of the people I've spoken to that own these say the base reads as a matte.
AMC: Stands for "advanced makeup component", This collection is perspiration resistant, contains vitamin E, and is talc-free. From what I could gather, the majority of AMC shades are a matte base with glitter, with the exception of #63, which is complete matte black without shimmer or glitter
AMC Shine: Same as AMC above, but more finely milled so these have a bit more sheen to them. According to the breakdown I was given, shades 24-36, 39, 41, and 43-49 compare to MAC's Veluxe Pearl finish, which is a soft metallic finish overlaid with pearl. In other words, shimmery, frosty or metallic, but not glittery. Other shades in the line have a high-frost to glittery finish.
