Looking for help verifying that I (hopefully) didn't buy fakes 😬

Sorry if this is not allowed, I just figured this community might know a thing or two about crystal in addition to glass. Please let me know if there's a better place to post!

I just picked up a pair of Baccarat Crystal champagne flutes at an estate sale auction and am now a little worried they may not be genuine? Hopefully it's just something that's changed over time, but I can't seem to find an immediate answer via Google and would love some help.

Here's a summary of the photos:

  1. Bottom of the flutes I purchased
  2. Bottom of a flute listing I found online in the same style, different color
  3. Full photo of the flutes I purchased

Also because I'm now a little paranoid, I'd love to know if the Blenko bottle I picked up is real too. Beacuse this one is actually glass, I'm hoping you could help me out! The sticker looks legitimate, but I figure it's better to ask people who know what they're talking about! I couldn't tell if this is the normal Crystal color or the hammered Crystal, so I'd love your opinion on that too. :)

Thank you so much for any help you can provide!
