In Brief:

Among all types of metal detecting, Beach Hunting or Beach Combing and Underwater Metal Detecting are the most productive for finding valuable gold and silver jewelry items.
Nevertheless, relic hunting and coin shooting, especially at the picnic grove hunt sites, also provide opportunities to unearth jewelry which, of course, is not as modern and valuable as the jewelry found on the beach or along the surf line in the ocean, but is still a pleasant addition with some historical value to one's collection of metal detecting finds.
