November-born ladies will fall in love with our 9ct yellow gold sky blue topaz stud earrings, part of our birthstone collection. Featuring 5mm genuine topaz gemstones, these studs have a dainty 8mm x 8mm face size (smaller than your fingernail) and weigh just 0.6 grams. That means you can wear them comfortably all day long. Party time, anyone?
