Not getting one. And even if I did, would buy man-made. They are a fraction of the cost and no normie or person off the street can or will be able to tell the difference. And, you do not support the ridiculous players in the industry.

Got lucky that significant other could quite easily care less for diamonds.

Fun fact: Israel is the world's Mecca for diamond Jewellers and must diamond cutting is done there or off there via business partnerships. It is not a stretch to say that if you want to support the Palestinian cause, then do not buy diamonds the usual way. Go figure how these things work.
