I’ve been wearing Maria Tash 3.5 mm studs in my second and third piercings for a while. Recently, I finally caved and got the 4.7 mm for my first piercings. The price is obviously steep compared to buying loose stones, but after years of considering other options, I decided to take the hit and get what I truly liked. No other setting looks quite like Maria Tash’s invisible diamond. In fact, because there are no prongs, the stones actually seem larger. I initially considered the 5 mm, but the height difference from 4.7 mm to 5 mm was surprisingly significant. I didn’t love how the earrings stuck out due to that, so I went with the 4.7 mm instead.
