The pictures are large (and clickable) to show detail, so they may take awhile to load. Most of the pictures are hiding behind the cut.
Let's get the non-golds out of the way.
The first two (Haley's Comet and Teal of Fortune) are similar, but the Wet 'n' Wild has fewer of the larger glitter particles. It also has tiny iridescent glitter (there is some of this in the Orly, also, but it's not as noticeable) that flashes gold to orange. Because there is less glitter, or at least less glitter that rises to the surface, and the interesting flashes of orange, Teal of Fortune has more depth. It also appears darker, though I'm not sure the base color is actually darker. I tried several different light sources, but couldn't manage to capture the orange flash, but I promise it's there.
Based on how they appear in the bottle, I would choose Haley's Comet (or it's proper dupes, Charla and Catch Me In Your Net), but I really love Teal of Fortune on the nail. Luckily, I don't have to choose just one!
The golds, part 1
The bottles are set in the order I applied them, left to right, thumb (or index finger, if there are only four) to pinkie.
I realize that Tipsy is obviously copper, rather than gold, but I remember someone suggesting that it was an affordable dupe of Golden Ticket. This just isn't the case. I love them both. Ipnotico gold probably could have stood two or three more layers of top coat. All of the matte glitters from Borghese's Scintillare collection eat topcoat like I eat ginger candy. It's not pretty, well, actually they are quite pretty, once they've had their fill.
under lamp to show holo
I intended to take these photos outside, to show of the holo as much as possible, but my camera died, and by the time the battery was charged up, the sun was gone. The lamp acted as a reasonable facsimile. As you can see, GR8 is the only linear holo, though Mega Bite may be in ideal lighting conditions. The holo particles are large, and more sparse than those in GR8, though not as large, or sparsely distributed as 3D. Donner and the snowman are both gold bases with holo glitter, and I'm inclined to lump 3D into that category as well.
That's all for now, I hope to have Part 2 up tomorrow.
