The variety is amazing! Everything from historic, museum-quality Ottoman necklaces to traditional gold, diamonds, rubies, emeralds, and contemporary, state-of-the-art modernist pieces in silver, gold and precious stones.
Istanbul's Grand Bazaar has several streets devoted to jewelry, and Nuruosmaniye Caddesi, the street east of the bazaar on the way to Sultanahmet, is lined with more jewelry shops, as are the side streets off of Nuruosmaniye.
In fact, in any town of any size in Turkey—and certainly in all covered bazaars—there will be jewelry shops.
But the best variety is likely to be in Istanbul.
