At Yoni Crystals it is our opinion that we do not sell ANY crystals that are unsafe for our sacred yoni temples. Rose Quartz can sometimes have a bad reputation because it is a more delicate stone than Jade, though she is 100% safe if used properly.Rose Quartz is more susceptible to thermal shock. Unlike Nephrite Jade which can resist quick changes in thermal temperature—like boiling in water to clean the egg—the molecular structure of Rose Quartz is more delicate and can crack or fissure when it goes through a drastic change in temperature. When an egg has a small crack or chip, this area is more susceptible to bacteria build-up which can cause infection.In any Yoni Egg practice, it is important to take delicate care of one's crystals and to thoroughly cleanse any place that can hold bacteria. This includes all drilled eggs, it is important to clean all drill hole areas (Jade, Rose Quartz, Obsidian ++) EACH time the egg is used. There is a convenience to Jade because it is structurally 'less porous' so you can boil the egg to disinfect it. However, other minerals that are more sensitive to thermal shock, like Rose Quartz or Obsidian, can be disinfected using other methods such as warm running water and organic soap.Although more attention must be used for these minerals we offer them because they are POWERFUL healers. Yoni Crystals and our Partners find it 100% worth the effort as we have an incredible array of crystal options for our healing and pleasure.
