While certain necklace types are more classic or conventional, a timeless kind of necklace will be something you adore and never want to take off. A pearl necklace, like a diamond pendant necklace, epitomises eternal elegance and may be passed down through generations. A heart necklace is another classic design that has been around for a long time. Another timeless option that may be readily combined with other jewellery is a sterling silver or gold initial necklace.
