1.34 Ct.Tw.Total Carat Weight Spinel Pair from Ceylon (Sri Lanka)

This matched pair of natural Ceylon blue spinels from The Natural Gemstone Company presents a compelling balance of color, proportion, and finish. Weighing 0.64 carats and 0.70 carats respectively, each stone is a round shape, mixed brilliant cut, with dimensions of 4.85 by 4.86 by 3.83 millimeters and 4.87 by 4.89 by 4.04 millimeters. The pair exhibits dark color intensity, a clarity grade of very slightly included when evaluated at eye level, and an excellent polish. There has been no enhancement applied to these stones, and their origin in Sri Lanka, historically known as Ceylon, contributes to their stable and desirable blue hue. These factual attributes describe a pair that is close in weight and closely matched in size, which is a fundamental starting point for consistent performance in matched set applications, particularly in halo settings that demand visual symmetry and balance.

The mixed brilliant cut employed here combines a faceting style that emphasizes both scintillation and depth, giving each spinel a lively surface flash while retaining an inner richness of tone. The excellent polish ensures that facet junctions remain crisp, supporting even light return across the crown facets, and reducing any risk of dull areas that could diminish contrast when paired with accent stones. The clarity, graded as very slightly included at eye level, means that inclusions are minimal and do not interfere with overall transparency, allowing the dark blue body color to read cleanly across the table. The slight difference in pavilion depth between the two stones, as reflected in the millimeter profiles, contributes to a subtly varied optical depth that can add character when the pair is set side by side in matched earring settings or as companion stones in a multi stone ring where uniform yet lively performance is required.

When set as the central elements of a halo design, these blue spinels will assert a distinctive visual presence through contrast and proportion. A halo of smaller, bright white diamonds or high clarity white sapphires will frame each spinel, creating a pronounced edge of light that elevates the perceived size of the center stone. The dark color intensity of the spinels works to anchor the eye, producing a deep central core against which the halo stones deliver maximum scintillation. Mixed brilliant faceting enhances this effect by supplying crisp surface sparkle that plays against the halo fire, while the very slight inclusions are of a nature that does not disrupt the overall field of color under typical viewing conditions. In circular halo profiles, the matched round shapes and closely matched millimeter dimensions support concentric symmetry, ensuring that the halo alignment appears seamless and that bezel or prong spacing can be minimized for a refined finish.

Practical considerations for design and care are straightforward and align with the attributes of these natural Ceylon spinels. Their weight range and proportions suit a variety of halo formats, including single row pavé halos, micro pavé halos, and double halo treatments, depending on the desired balance between brilliance and contrast. Metal choice will influence the final visual effect, with white metals enhancing the brilliance of the halo and increasing the apparent contrast with the blue center, and warmer metals softening the contrast for a more tonal presentation. Secure prong settings or low profile bezels can preserve the stones integrity while allowing the mixed brilliant cut to interact optimally with incoming light. Routine cleaning with a mild detergent solution and a soft brush will maintain surface polish and sparkle, and periodic professional inspection will confirm setting security. The Natural Gemstone Company can provide measured photographs, matching reports, and advice on halo proportions to assist in translating these specifications into a finished piece that emphasizes the distinctive depth and compositional harmony of this spinel pair.
