0.56 Ct.Tw.Total Carat Weight Ruby Pair from Mozambique

This matched pair from The Natural Ruby Company consists of two transparent princess shape red rubies, each weighing 0.28 carats. The stones measure 3.44 x 3.42 x 2.04 mm and 3.45 x 3.44 x 2.22 mm respectively, and both are finished in a precision princess cut with an excellent polish. Clarity is graded as very slightly included, evaluated at eye level, indicating minimal internal features that do not compromise overall transparency or light return. Color is classified as intense red, exhibiting saturated hue with strong chroma and good tone balance across both stones. Enhancement disclosure is heat treated, which is a stable and widely accepted enhancement that optimizes color saturation and reduces silk or rutile dispersions, and origin is Mozambique, a source known for producing vivid and clean ruby material with consistent crystallographic habit.

From a lapidary and setting perspective these princess cuts demonstrate tight symmetry and controlled pavilion depth, which support efficient light performance and focused scintillation. The first gem has a depth of approximately 59.3 percent relative to its width, calculated from 2.04 mm over 3.44 mm, and the second has a depth of approximately 64.3 percent relative to its width, calculated from 2.22 mm over 3.45 mm, yielding slightly different pavilion proportions that nevertheless harmonize visually when paired. The crown and pavilion facet architecture is executed to emphasize a square outline with crisp facet junctions, resulting in clean table reflection and defined crown facet patterning. Facet alignment and girdle uniformity are consistent with precision cutting goals, ensuring predictable behavior under both direct and diffused lighting. The excellent polish enhances microfacet integrity, improving contrast between flashes and broad zones of vivid red, and the minimal visible inclusions serve as natural fingerprint characteristics without interrupting optical continuity.

These princess rubies are highly versatile for a wide range of jewelry applications, from classic stud earrings and channel set bands to more intricate halo pendants and bespoke three stone designs. Their square geometry makes them ideal for paired settings where mirror imaging is required, and their dimensions are well suited to tight bezel seats, low profile prong baskets, and precision channel rails used in contemporary settings. The intense red saturation pairs elegantly with white metals to maximize contrast, and with warm metals such as yellow or rose gold to enrich perceived depth of color, offering designers latitude in metallurgical choices. For manufacturing tolerances, bench technicians will appreciate the minimal variance between the two stones, allowing for a typical setting allowance of one to two tenths of a millimeter for seat clearance while maintaining square alignment. As with all fine rubies from The Natural Ruby Company, provenance and treatment are fully disclosed, and these stones are supplied with detailed measurements and grading attributes to facilitate informed design decisions and to ensure predictable performance in final fabricated pieces.
