It was a conscious decision costume designer, Catherine Martin, made to use real gems and jewelry in the filming of “The Great Gatsby” which hit theatres last weekend. She admitted to Elle Magazine in September that is was much more about making sure the right image was conveyed rather than the chance to be surrounded by expensive gems and jewels all day.
Many films these days that are shot with regular 2D cameras, use fake stones and less expensive jewelry because they are all considered props, hence the name costume jewelry. Designers can find any types of jewelry that will imitate the real stone’s look, but Martin felt that since the movie was being filmed in 3D and HD that the audience would be able to tell if a stone was real or fake. Camera tests are often done with costumes, make up, and set designs to insure that the scene is coming across perfectly, therefore Martin must have noticed in the camera tests that the fake cubic zirconia diamonds were not as brilliants as real Diamonds. The idea that a real diamond sparkles more than a cubic zirconia is a fact. A diamond sparkles with a refractive index, the index used to measure how a ray of light is bent and travels through an object, of 2.42, while a cubic zirconia is 1.18. Obviously a diamond has more reflection and therefore more sparkle.
