HOW TO CHOOSE

As with all types of fancy-shaped diamonds, the first consideration in choosing a marquise should be the quality of its overall appearance. It goes without saying that you should select a stone with high transparency that sparkles brightly. Take care, however, not to be mesmerized by brilliance and neglect considering the beauty of the gemstone's appearance and shape.

When selecting a large marquise, it is best to choose an appropriate shape while keeping in mind an image of the finished jewelry. Since gemstones are created by nature, demanding too much of a stone is unreasonable. Choosing a stone that impresses you as beautiful will ultimately lead to a good purchase. In any case, it is important to choose a jeweler that fully understands the quality of gemstones.

The value of a one-carat-size marquise-cut diamond of jewelry is approximately US $6,000 for the stone alone. (2001)
