A pair of the most perfectly minimalist stud earrings, that you can wear every day because the posts are solid gold and will never bother your ears! What it Represents: Rainbows can hold so much meaning... representing a baby after loss, or just a reminder of sunshine and love especially after hard times. These match perfectly to our Hugging Rainbow Ring. The Materials: I wanted to make these as hypoallergenic AND as good of a price as possible. So the post in every pair (aka the part that you don't see, the part going through your piercing) is SOLID 18k gold + you can choose if you want the Rainbow front to be Rose Gold Filled, Gold Filled, or Solid Sterling Silver. We chose 18k for the posts because that's a really pure gold and really unlikely to cause any allergy to people with metal sensitivities. With SOLID gold being used, the materials to make these are very very pricey. But the high quality metal is worth it! This item is ready to ship. Refer to FAQ for processing times. xox Kelsey
