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

This matched pair of natural rubies from The Natural Ruby Company presents exacting gemological qualities that will satisfy an educated buyer seeking both beauty and technical integrity. The stones weigh 0.25 carat and 0.26 carat respectively, and measure 3.70 by 3.69 by 2.46 millimeters, and 3.67 by 3.71 by 2.67 millimeters. Each is fashioned in a round shape with a mixed brilliant cut, delivering strong light return and lively scintillation. Color is described as a pinkish red with intense color intensity, and polish is graded excellent. Clarity is assessed as very very slightly included, evaluated at eye level, which indicates minimal inclusions that do not detract from face up appearance. Enhancement is by heat treatment, a widely accepted and stable treatment that improves color and clarity, and origin is Mozambique, a source increasingly recognized for high quality ruby material.

From a gemological perspective these rubies combine the attributes collectors and designers prize, color and clarity working together to create vivid saturation and strong presence in small sizes. The mixed brilliant cut is chosen to maximize brilliance and return of light for round stones of this diameter, making them particularly effective for pierced earring settings where symmetry and paired matching are essential. The very very slightly included clarity grade means that the stones will present a clean face up window at normal viewing distances, while retained internal characteristics testify to natural formation and provide identification markers when examined under magnification. Heat treatment is fully disclosed, and is considered a stable enhancement that improves long term appearance without compromising structural integrity, which is important for settings that will be worn daily.

The Natural Ruby Company follows a clear and accountable approach to sourcing from Mozambique, emphasizing traceability, ethical labor practices, and environmental stewardship. Our procurement begins with established relationships with responsible producers and vetted trading partners who operate in compliance with local regulations and internationally recognized standards. We maintain documented chain of custody records from mine to consumer, and we require suppliers to demonstrate fair labor conditions, transparent wage practices, and measures to limit environmental impact during extraction and processing. Where practical we support community development initiatives in mining regions, including education and health programs, and we encourage suppliers to implement rehabilitation plans for disturbed land. All treatments and the country of origin are disclosed up front, and we can provide traceability documentation or independent laboratory reports on request to support due diligence and buyer confidence.

For practical use these rubies are well suited to a matched pair of stud earrings, minimalist settings, or as accent stones in bespoke designs, where their intense hue and polished facets will complement both white and yellow precious metals. Rubies are durable, ranking high on the Mohs hardness scale, and with routine care they will retain brilliance for generations, making them appropriate for personal commissions and heirloom pieces. We invite buyers to request additional photographs under daylight and controlled lighting, and to obtain a third party report if desired, as we welcome independent verification of the attributes we describe. The Natural Ruby Company stands behind transparent disclosure, quality matching, and ethical sourcing, and we are available to advise on mounting options, matching tolerances, and long term care to ensure these Mozambique rubies perform beautifully in your finished jewelry.
