Hourglass Ghost is a limited edition cheek palette that retails for $58.00 and contains 0.16 oz.
Hourglass Ghost (Holiday 2019) Ambient Lighting Blush QuadHourglass Ghost (Holiday 2019) Ambient Lighting Blush Quad ($58.00 for 0.16 oz.) is a new, limited edition palette that features two brand-new shades, one repromote (but never sold individually), and one permanently available shade (Brilliant Nude). Most of the shades had buildable pigmentation (as marketed), natural-to-luminous finishes, were blendable and easy to use, and performed consistently with past shades in the formula.
Hourglass' blushes retail for $40.00 for 0.15 oz. or $266.67/oz. They also sell miniature sizes in four shades, which retail for $24.00 for 0.04 oz. or $600.00/oz. (pretty small--0.04 oz less weight than the average, full-sized eyeshadow). Based on the standard-sized product, the quad has a retail value of $42.67. If you use the miniature size as the base, then it is like getting four minis in one ($96 worth).
I think Hourglass has heard from me along with many others over the years that we'd like to see a second (or even a third!) option. Especially with the blush quad release, I actually think quads might have been the perfect way to offer the right variety to hit on ranges of skin tones - I could very much see a really go-to, travel-friendly set of quads for light, medium, dark, and deep (I know four might as well be asking for the world). You could have one Ambient Lighting Powder (finishing powder), two blushes, and one of the Strobe Lighting Powders (highlighting).
But at the very least, the quad format leaves me puzzled why they didn't release a deeper version for darker skin tones. It's such a fantastic formula, but I feel like the depth of colors in the range--both permanent and what's released in palettes--could be so much better.
