Rose Gold Star Studs with Rubies
These 14 K rose gold studs are measure 9mm and I centered the posts as much as possible, directly above the opening for the gemstone.
The little gems in the center are 2mm heated rubies. I could use other gems as well (I can get these castings in rose, white and yellow gold). I think they are actually meant for diamonds.
Ruby is the birthstone of July.
