If she wanted a more noticeably pink quartz heart, could she not have contacted the seller and asked if they had any darker pink pieces? There are pictures of everything on Etsy, so it's not like she didn't see what the item looked like before making a purchase.
A cursory glance at other sellers' items turned up some $10 bright pink heart-shaped gems (moissanite) that may have been more suited to Moo's picky bullshit needs. So she just had to not be lazy, or she just had to understand that quartz is not a deeply colored stone and to look for something different.
I wish gender reveals would fucking die already. At best, the Moos get so shitty about the pink not being pink enough or the blue not being blue enough (because it's never the Duhs who give a fuck). At worst, these bitches have started forest fires and even killed people with their extravagent displays that share the gender of their imminent mistakes instead of just using their mouths to tell people.
