Hi,
I'm just new to this forum and I was wondering, is someone able to please tell me what a 'flameball' is? Also, by exotics, are you referring to the pearls being 'rare' or an 'exotic colour', or is it in reference to another descriptive term such as 'the orient' used to describe difraction? (Have read the optics post and am more science based so just trying to understand the selling terms?)
I have never heard anyone use these terms before IRL. Thanks!
