A topazian person is attracted to non-binary people and/or prioritizes their attraction to non-binary people over other attractions they may have. Topazian is an umbrella term, like sapphic and achillean, though it can also be used as an identity by itself.
Topazian was coined by the now deactivated Tumblr user Saturnic-vapour. The flag was also designed by them some time around June 23, 2018. The colors on flag represent both being male and female (pink and blue) and loving non-binary people (yellow) as well as being the colors of topaz.
