4.03 Ct. Ruby from Mozambique

This transparent 4.03 carat oval ruby from Mozambique presents a balanced combination of size, shape, and optical performance. Measuring 10.83 x 8.16 x 4.60 mm, the stone’s proportions offer an ideal platform for bespoke settings, with a mixed brilliant cut that enhances both scintillation and depth of color. The ruby displays vivid color intensity that reads true in a variety of lighting conditions, supported by an excellent polish that maximizes surface reflection and visual appeal. Clarity is graded as slightly included at eye level, a common and stable characteristic that is typically unobtrusive in finished jewelry. The gem has been heat treated, a standard and stable enhancement, and it retains strong transparency and saturation after treatment. This combination of attributes reflects The Natural Ruby Company’s commitment to presenting natural rubies with clear, verifiable information for informed design decisions.

For custom jewelry, this oval 4.03 carat ruby is particularly well suited due to its versatile outline and comfortable table size. The length and width balance allows designers to consider a wide range of mounting styles, including classic four or six prong solitaire settings, elegant halo compositions that increase perceived size without obscuring the stone, and low profile bezels for everyday wear. The 4.60 mm depth provides sufficient pavilion for secure bezel seats and allows experienced setters to optimize light return while minimizing visible inclusions. Its mixed brilliant cut produces a lively face up appearance, making it an excellent center stone for rings and pendants where brilliance and color are priorities. When integrated into bespoke pieces, the ruby’s vivid red tone pairs effectively with both warm metals such as yellow and rose gold and with cool metals such as platinum and white gold for contrasting presentations. The slightly included clarity recommends considerate orientation of the stone in the setting to conceal or minimize inclusion visibility when viewed face up. Presented by The Natural Ruby Company, this ruby is an excellent candidate for custom commissions and high quality repairs, offering a substantial presence on the finger or in a pendant while providing the practical considerations that experienced jewelers require for precision setting and long term wear.
