Hourglass has these highlighter/blush hybrids using Ambient Lighting Powder and are available in 7 shades. They use Photoluminescent Technology to create depth and a soft focus. I've bought 2 shades from Sephora: Diffused Heat and Mood Exposure.
All the blushes come in these gold, plastic containers that I'm not a big fan of, they're very light and I would've preferred them to have a bit of weight.
Diffused Heat
Diffused heat is a vibrant, poppy coloured blush combined with the Diffused Light ambient lighting powder. It's my absolute favourite and my holy grail blush for every day use! It looks intense in the pan but with a light swipe, you get a soft coral pink on your cheeks. It doesn't look as bright, warm or sparkly once applied! This shade should be flattering for most skin colours, I've tested this on my friend who's between NC40-50 and it looked great on her. Diffused Heat is pinker than Nars Orgasm Blush (another cult classic), which is far peachier.
Mood Exposure
Mood exposure is a soft plum blush mixed with Mood Light ambient lighting powder. It looks a bit flat in the pan, but mixed with the highlighter gives a soft, bright complexion. This shade can look very different on various skin colours. It may be more rosey for some, or look more bronze/plum for others (like myself). This is definitely a gorgeous shade, but I would try it on at your nearest Sephora before buying it.
Swatches
Both swatches are done with a heavy hand and look different on my face. Diffused heat is less pink and mood exposure is less bronze. You can enlarge the photos by clicking them.

Here's a close-up of the swatches:
Hourglass Ambient Lighting Blush retails for $41 CAD. It also comes in 5 other shades: Dim Infusion, Ethereal Glow, Luminous Flash, Radiant Magenta and Incandescent Electra (which was previously only available in the blush palette and I will probably end up buying).
They're available at Sephora! :)
