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

When you are searching for a pair of gemstones that will resolve a long standing quest for balance, beauty, and lasting wearability, these cobalt spinels from The Natural Gemstone Company answer that call. Each stone presents a rare and vivid blue that reads as intensely saturated without appearing heavy or dark, making them immediately wearable and adaptable to many styles. The pair weigh 3.09 carats and 3.04 carats respectively, and their oval shape delivers a classic silhouette that flatters the finger, the ear, or a pendant. The dimensions are 9.68 x 7.63 x 6.02 mm and 9.36 x 7.52 x 5.94 mm, and the mixed brilliant cut gives them a lively play of light across the table and through the pavilion. At eye level the clarity grade evaluates as very slightly included, which means they are clean enough to sparkle freely while retaining natural character. The polish is excellent and the color intensity registers as intense, with no enhancement, originating from Ceylon Sri Lanka. The untreated nature of these stones enhances their appeal for clients who want authenticity, and the combination of brilliant cut and excellent polish ensures they reflect light with a crisp, energetic fire that will integrate seamlessly with fine jewelry.

If your goal is to match these spinels to existing pieces in your collection, they offer a perfect starting point because their color reads as a flexible, jewel tone blue that harmonizes with both white metals and warm tones. For clients wanting continuity with white gold or platinum pieces, the cool blue will sing against those metals and the mixed brilliant cut will complement the sparkle of diamonds without being overshadowed. If your existing collection favors yellow gold or rose gold, the blue will pop beautifully, producing a complementary contrast that elevates both the metal and the stone. Because the weights are closely matched, they sit as an even pair for stud earrings, for a two stone ring layout, or as matching accents in a bespoke three stone engagement design. If you already own sapphires or tanzanites, these cobalt spinels make elegant companions, and we can advise on side stone choices and proportions that maintain visual balance. The slight difference in size between the two stones is within normal matched pair tolerances and can be managed in the mounting stage so that the finished piece reads perfectly symmetrical to the eye.

Customization is where these stones truly become personal, and The Natural Gemstone Company excels at tailoring the final design to your needs. We can recommend settings that hold each oval in identical orientation to ensure perfect face up symmetry, or offset them in a complementary layout for a modern, asymmetrical look. For a classic matched pair of studs, a four prong or six prong basket will maximize light return and secure wear, while a bezel setting will give a contemporary, low profile look that is ideal for daily wear. For rings, consider a halo of small brilliant diamonds to intensify the perceived color and size, or a tapered baguette shoulder to create a sleek, elongating effect. If your existing jewelry has a particular metal tone or engraving style, we can replicate those details to create a cohesive set. We can also design mounting cups or bezels to accommodate the exact dimensions, ensuring the stones sit flush and centered. For collectors who prefer minimal alteration, we provide secure setting options that require no recutting or repolishing, preserving the stones in their natural, untreated state. For clients who desire precise dimensional matching, our lapidary recommendations include careful re profiling within safe limits, however most clients prefer to retain the original excellent polish and mixed brilliant faceting to maintain the lively optical performance that these spinels show.

Working with The Natural Gemstone Company means you will have a straightforward path from selection to finished jewelry, with attentive guidance at every step so that these cobalt spinels integrate seamlessly into your life and your collection. We offer personalized consultations to review your existing pieces, to create CAD visuals that show how the new stones will look in your chosen setting, and to discuss metal choices, accent stones, and practical details such as prong height and bezel lip, all to ensure a harmonious match. Our sourcing from Ceylon Sri Lanka is documented and our dedication to natural, unenhanced gemstones means you receive a pair with genuine color and character. These spinels are durable enough for everyday wear, and their intense color, matched faces, and excellent polish make them both a statement and a subtle enhancement of what you already cherish.
