Tom Ford Beauty Surge Lip Spark is a deeper gold with larger, chunkier flecks of glitter paired with a warmer, more brown base. It had more semi-opaque coverage when I swatched it, but on my lips, it seemed more semi-sheer to medium in coverage. The texture was sparkly; I could feel the edges of the glitter as I applied the lipstick and if I pressed my lips together. This shade seemed to have the largest particles, and it also applied the worst in the range where the glitter clumped up and emphasized my lip texture. It did not go on evenly either. It stayed on decently for three and a half hours and was lightly moisturizing while worn.
Tom Ford Beauty Thrust Lip Spark is a medium, rosy copper with warmer, brown undertones and flecks of pink and gold glitter. It had semi-opaque color coverage that applied evenly and smoothly across my lips with just the barest amount of texture (from all the glitter). The texture was lightweight, emollient without being heavy or slippery, and comfortable to wear. It had a very high-shine, reflective finish with enough glossiness that prevented the more metallic/glittery finish from emphasizing my lip texture. It wore well for four hours on me and was lightly hydrating over time.
