Inspiredesign Jewelry - Rock Island L D: I proposed to my girlfriend of 4 years 2 months ago and our custom rings from Inspiredesign are PERFECT! The black stone is black spinel and purple is amethyst and both are in white gold. The turn around time was insanely quick and the quality is phenomenal. We constantly get complements. They’re everything we wanted and more! Can’t thank this place enough for the amazing job they did!
