I recently read a column suggesting that the wearing of any precious stones, especially sparkly ones, is not appropriate until after six (excluding one's wedding and engagement rings.) I was quite surprised to hear this, so of course I had to consult my jewelry-loving friends here. Now I agree that huge cocktail rings or diamond tennis bracelets are probably better reserved for evening, in addition to long dangly diamond earrings. However, I own a pair of 1.5 carat total weight diamond studs (princess cut) that I often leave in 24/7! I always thought of them as a classic work accessory. What do you girls think? Are diamond studs appropriate for day? Does size have something to do with it? Or cut? I look forward to reading your opinions!
