I purchased the fabled "Amber Diamond" powder as a splurge after a following a rather austere budget for a while - and what a luxury it felt like! The packaging of Dior products is second to none - when that gorgeous blue compact slid out of the dustbag, I knew whatever might be inside would just be gravy.
Amber Diamond quickly became my go-to highlighter for 90% of my days. The glow it imparts is lovely and natural, and I enjoy that in a pinch, the colors can be used individually as eyeshadows. I do not experience fading from this product until at least hour 8 of wear, which I consider exceptional from a supplemental powder. And I know - tagging this a "great value" when the price tag is as hefty as it is? I would be remiss not to, however - I've been working on mine for a year and a half with no sign of hitting pan in the imminent future.
