This is my new favourite glass - not that I have fallen out of love with Dark Fossil or Raven Sky, but this is truly wonderful.
This is Effetre 293 - Avorio Dark Lapis. As you might guess, Avorio is Italian for Ivory, and this glass appears to be a streaky blend of Ivory and Lapis.
I have 4 Avorios to test - this is the first of them - and they appear to be a line of something plus ivory. I'm pretty excited to get to the rest of them as well.
I did experience a bit of shocking - but it wasn't extreme, and given the colours - worth it.
