So I recently raided my local Discount NI and this was 1 of the wondrous gems that I found for 99p.
Purple Diamond is a linear holo. A pale purple polish with the most beautiful sparkle. 2 coats achieved full opacity.
Unlike the only other linear holo I own by Gosh the application was perfect, no patchiness or bald spots.
For some reason without the flash tonight my pics look really washed out =/
Hoping to get up again to nab a few more gems.
