Methods, apparatus, and systems for fabricating diffractive structures on gemstones for high optical performance are provided. In one aspect, a method includes obtaining a plurality of gemstone characteristics of a gemstone, determining that the gemstone exhibits each of the plurality of gemstone characteristics within a respective predetermined range, identifying a diffractive structure setting associated with a combination of the respective predetermined ranges for the plurality of gemstone characteristics, and fabricating diffractive structures on the gemstone according to the diffractive structure setting.

Fabricating diffractive structures on gemstones for high optical performance

Methods, apparatus, and systems for managing optical characteristics of gemstones with diffractive structures are provided. In one aspect, a method includes obtaining a three-dimensional model of a gemstone including representations of surfaces of the gemstone, identifying a region on a surface of the gemstone having an optical value higher than one or more other regions on the surface of the gemstone by analyzing the three-dimensional model of the gemstone, and determining a diffractive structure to be arranged on the identified region of the surface of the gemstone, such that the gemstone with the diffractive structure has a higher optical performance than the gemstone without the diffractive structure. The method can also include fabricating the determined diffractive structure on the identified region of the surface of the gemstone.
