Shape is an important consideration when buying a diamond as it directly influences price. Round diamonds tend to be priced higher than other shapes because of their incredible brilliance, market demand, and increased manufacturing costs. Non-round diamonds are referred to as fancy shapes. Blue Nile offers nine fancy options, including princess, emerald, Asscher, cushion, marquise, radiant, oval, pear and heart.
“Buy shy” to save money. Select a carat weight slightly below the whole and half-carat marks. For example, instead of a 2.00 carat diamond, consider buying a 1.90 carat weight. This will save a considerable amount of money, and the slight difference will never be noticed.
