Does Purely Cosmetics Diamond Powder stand up to the test?

I won this product from Enkore at IMATS. I follow Purely Cosmetics on twitter but I have not had the opportunity to try out the products. One of the most popular items from Purely Cosmetics is their Diamond Powder. It is often compared to MUFE HD powder at a fraction of the cost.
Diamond Perfect Finish is a unique product made with real diamonds and a patented diamond complex to create a flawless finish. Your face will have an airbrushed look.With nearly a carat of diamonds in each full sized jar, Diamond Perfect Finish works perfectly for photography and high definition, and is superior in performance to products such as Makeup Forever's High Definition Finishing Powder.
As a WOC, I really have to watch out for powders that will make me ashy. 
Scratch that..
Actually this can happen to anyone. 
Exhibit A:

First I have applied my favorite HD foundation on the top of my hand

Then I dabbed the powder on my hand.
I did it heavily, so you all can see the finish of the powder.
 I used my Sigma F80 to buff in the powder.
This picture is the determining factor to see if it gives me an white cast :|

Question:
Do you stay away from white powders?

FACEatelier Lip Glaze Swatch in Shiraz- Perfect for fall

I have received a good amount of requests to see swatches of my IMATS haul. I'm going to start out with one of my favorite lip glosses right now- FACEatelier Lip Glaze in Shiraz.
This glaze was picked out for me personally by the President / CEO Debbie. After our talk about their gorgeous lipstick in Revenge, she suggested a glaze to compliment it or wear alone. Click here to check out my lip swatches of Revenge.

Isn't Shiraz such a fab color! This swatch is on bare lips

This is Shiraz layered over a Berry lipstick

So ladies if your searching for a great plum gloss check out FACEatelier.

I need help! What are you spending your Sephora gift Card on?

As you all know Sephora sent out gift cards to all Beauty Insiders! $15 of any $40 purchase. Since I will be going to USA this week, it would be best to spend it in a Sephora which carries all the brands :D

BUT my issue is I'm stuck!! Soooo many things to buy. I need help narrowing it down or choosing something else. My bugdet is Under $50...minus the giftcard I will be spending $35.

There are my top picks!

Sephora by OPI set: 18 shades

Sephora Flashy Liner Waterproof Eye Pencil Set


GDH Dazzle Gift Set

Korres Long-Wear Age-Repair Lip Kit
