0.47 Ct. Ruby from Mozambique

This Mozambique origin ruby offered by The Natural Ruby Company is a precisely executed emerald cut, weighing 0.47 carat, with dimensions 5.25 x 3.03 x 2.58 mm. The stone presents as transparent with a medium intense red color intensity, and it has been heat treated to optimize tone and saturation in a manner consistent with established industry practice. The proportions of the rectangular emerald cut are compact yet elongated, creating a visually larger face up presence relative to the measured weight. The table is broad and flat, and the step facet geometry produces a well defined table reflection plane that emphasizes the body color rather than scintillating brilliance, which is characteristic of this faceting style. This combination of small carat weight and efficient face up area makes the specimen particularly impactful as a single stone statement element in contemporary fine jewelry.

From a cutting and finish perspective the gem exemplifies careful craftsmanship, with an excellent polish that yields crisp facet junctions and minimal surface haze. The emerald cut executed here includes well aligned crown and pavilion step facets that run parallel to the long axis, producing the classic hall of mirrors effect that accentuates color zoning and internal clarity characteristics. The pavilion steps are evenly spaced to control light return and deepen the apparent saturation when viewed table up. The stone was evaluated as very slightly included at eye level, which indicates the presence of small, localized internal features that do not materially interrupt transparency or the integrity of facet planes. Those inclusions are sufficiently minor to allow clean facet reflections and to permit the emerald cut to perform as intended by enhancing color tone without distracting brilliance break up.

Color and stability are central to this rubys appeal, and the medium intense grade recorded aligns with a vivid red that remains versatile in various mounting contexts. Heat treatment has been applied, which is a standard and stable enhancement for Mozambican rubies, improving color uniformity and reducing absorbent or altered inclusions without compromising structural stability. The stone demonstrates an even distribution of color across the table and shoulders, with slightly deeper saturation along the pavilion edges, a response that is consistent with step cut refractive behavior in corundum. When tilted under directional light the gem reveals the expected slight anisotropic response common to rubies, where hue and tone can vary subtly off axis, offering a controlled dynamism that is attractive to connoisseurs who prefer color modulation rather than excessive flash.

Given its dimensions, clarity, and finish, this 0.47 carat emerald cut ruby is exceptionally well suited to function as a focused statement piece. The elongated rectangle translates elegantly to ring centers with minimal bezel metal intrusion, and it also adapts cleanly to solitaire pendant settings where the broad table can be showcased. Because the emerald cut emphasizes color and clarity over dispersion, this ruby will read larger than its weight might suggest, and it will provide a strong visual anchor in designs that favor architectural lines and modern minimalism. For jewelers and end buyers seeking a piece where precise cutting, stable enhancement, and source transparency are priorities, this ruby from Mozambique offered by The Natural Ruby Company presents a balanced technical profile that supports confident design decisions.
