1.10 Ct. Ruby from Mozambique

This specimen from The Natural Ruby Company is a transparent, round shape ruby weighing 1.10 carat, with precise dimensions of 5.71 by 5.75 by 4.11 millimeters. The stone is faceted in a mixed brilliant cut, a design that combines a brilliant style crown with a step or modified pavilion to optimize both brilliance and face up color. The clarity has been graded as very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not materially impede transparency or visual appeal. The color is described as pinkish red with vivid intensity, and the polish has been assessed as excellent, yielding sharp facet junctions and high surface luster. The ruby has undergone routine heat treatment to enhance color and clarity, and it is documented as originating from Mozambique, a source now renowned for producing strongly saturated, high quality rubies that rival traditional Asian sources.

From a gemological perspective, the combination of composition and origin explains much of this ruby's appeal. Rubies are gem quality corundum, an aluminum oxide matrix colored by trace chromium ions, and the amount and distribution of chromium determines the depth and nuance of red to pink hues. Mozambique rubies typically present a strong, vivid saturation with slightly purplish to pinkish overtones in some lighting, and they often achieve rich, even color zones after careful cutting and heat enhancement. Heat treatment in rubies is an established and stable enhancement, applied to improve clarity by altering the appearance of certain inclusions and to deepen or homogenize the color. This treatment is accepted within the trade when fully disclosed, and it does not impact the fundamental durability of corundum, which rates nine on the Mohs scale and remains an excellent choice for everyday wear.

The mixed brilliant cut of this piece is particularly important to its visual performance and collector value. The cutter has balanced crown and pavilion facet angles to produce an engaging combination of brilliance, scintillation, and color saturation when viewed face up. The mixed cut allows the stone to display strong flash and pinpoint brilliance from the brilliant crown facets, while the modified pavilion helps to retain color by returning light in a manner that emphasizes the body tone and saturation. The excellent polish enhances light transmission, making the facets crisp and contributing to a lively play of light across the table. In hand, photographs and loupe inspection reveal that the stone presents a concentrated color center, with the mixed brilliant geometry creating a lively pattern of reflections that will make this ruby read as a dramatic centerpiece in rings, pendants, or bespoke settings.

For an educated buyer, several factors combine to make this ruby a thoughtful acquisition. The carat weight of 1.10 offers a sweet spot between everyday wearability and collectible presence, and the vivid color intensity is a primary driver of value in rubies. The clarity grade of very slightly included at eye level indicates that the stone retains excellent transparency and spectacle, while the measured dimensions are consistent with a well proportioned round that will sit attractively in a variety of mounts. Origin matters in the marketplace, and Mozambique has become a respected source for rubies that match or exceed quality from other regions, creating strong demand among connoisseurs. Heat treatment is fully disclosed, and while unheated rubies command premiums, responsibly treated stones from reputable origins represent significant value due to improved availability and predictability. The Natural Ruby Company maintains transparent documentation practices and can assist with third party certification for buyers seeking formal laboratory reports.

Care, setting guidance, and acquisition considerations complete the practical picture. As a corundum species specimen, this ruby is robust and suitable for regular wear, yet it benefits from routine care, including gentle ultrasonic cleaning when securely mounted, warm soapy water rinse, and avoidance of extreme thermal shock or strong acids. When setting this 1.10 carat round mixed brilliant ruby, a well designed setting that protects the girdle while allowing light to enter the pavilion will maximize both brilliance and color saturation. Prong settings, bezel alternatives with thoughtful light apertures, and halo designs that enhance apparent size are all viable choices depending on personal taste and design intent. If desired, The Natural Ruby Company can provide additional detailed photos, videos, and assistance with third party grading services to support insurance or appraisal needs, and we will disclose all treatment and origin information to ensure you purchase with confidence.
