Help with yarn

I am looking to find this yarn. No one seems to know what it is. It is defined as “Shimmery crochet thread”. Any ideas?

On the left you’ll see “crochet thread” with several brands. Some of them looked like they could be it…one was called DMC Brilliant.

It could also maybe be tatting thread?

looks like number 10 crochet thread: in michaels it is separate from the yarn: in JoAnns it is near the cottons. DMC makes a few glittery shades… and Aunt Lydia’s also makes some gold/silver mixed colors.

I think I found it. I looks to be OmegaCrys.

Does anyone know where I can find Omega Crochet threads in person? I’ll look at Joanns and Michaels tonight.
