Bobbi Brown Rose Gold is a slightly warm-toned, light-medium copper with a frost finish. It is a limited edition highlighter that retails for $46.00 and contains 0.4 oz.
Bobbi Brown Rose Gold Shimmerbrick ($39.00 for 0.40 oz.) is supposed to create a "soft, warm pink glow." Each shade can also be used as an eyeshadow. When blended together, it takes on a warm copper with just a hint of pink/rose. It has a frosted shimmer-sheen and has enough pigmentation to give cheeks a little color (more in the form of warmth) as well as highlight. Laura Mercier Rose Rendezvous is a little darker but similar. MAC Redhead looks nearly identical to me.
The original Shimmer Brick Compact. This shimmering, brush-on powder creates a deep, bronzy glow. Works well with neutral and deep blush shades. To apply: Sweep the Face Blender Brush through all five shades and dust lightly on cheekbones after blush. Focus on applying shimmer on the top of cheekbones. To add a highlight to eyes, apply the lightest shade in the compact just under browbone with fingertips or the Eye Smudge Brush.
