Baguette-cut diamonds are step cut diamonds with a long, rectangular shape. They are mainly used as side stones and come in small weights, usually less than one carat.
This diamond cut emerged in the early 20th century, reflecting the geometric styles popular in design and architecture during that era. Baguettes were first used in costume jewelry, but the simple, clean lines of the baguette cut and the ability to set them side by side with no gaps inspired jewelers to use them to make jewelry pieces. A baguette-cut diamond usually has only 14 facets, so it should be of high quality as its unique cut easily reveals any blemishes.
