Spectra Fine Jewelry Ceylon Sapphire Diamond Halo Cocktail Engagement Ring 19.28ct

Beautifully crafted by Spectra Fine Jewelry in the 21st century, 2019, this Ceylon Sapphire Diamond Halo Cocktail Engagement Ring is both resplendent and restrained, balancing all elements in pleasing harmony. The ring is crafted in platinum and features an oval blue sapphire with an estimated weight of 19.28 carats. The sapphire is accompanied by report no. CS 67889 dated 20 May 2015 from the America Gemological Laboratories (AGL) stating that it is a natural corundum blue sapphire of Ceylon (Sri Lanka) origin with no indication of thermal treatment. Unheated sapphires are valuable and rare, as the majority of colored gemstones on the market are heat-treated to improve color saturation and clarity. The center stone is accented with rose-cut and baguette diamonds weighing approximately 3.00 carats total of G color, VS clarity, arranged in a striking and unusual double halo.

During the Edwardian era (1901-1915) and subsequent Art Deco period, it was popular for garlands, ribbons, and wreaths to be depicted in jewels, and their bright sparkle in this contemporary example matched with gleaming platinum gives this halo its retro charm. The skillfully realized pattern has a pleasing mathematical precision and is a testament to Spectra Fine Jewelry’s studied eye and fine artisanship . Four tapered baguette diamonds coincide with 4 talon prongs placed at ordinal points around the center stone creating a geometric counterpoint to the 32 rose-cut staggered diamonds.

The baguette-cut diamond was at its height of popularity in the 1920s. In fact, the rectangular shape of this fancy cut stone helped to develop the symmetrical geometric style that is synonymous with the Art Deco movement. The rose-cut diamond dates back to the early 15th century and was first popular in the 1700s. Rose-cut diamonds are individually unique, more luminous than sparkly, and allow the light to move through and across the stone, giving a more transparent glow and subtle shine. With a flat base and a faceted domed profile, round rose-cut diamonds usually have 24 facets, compared to the 58 facets of a round brilliant cut. Adding interest and texture, the two halos are progressively angled away from the sapphire, creating varied planes for the diamonds to catch the light.

The three most famous regions for blue sapphire are Kashmir, Myanmar (Burma), and Sri Lanka (Ceylon). Ceylon sapphire have nuanced variation in color, density, composition, translucence, and purity, but were originally celebrated for their vibrant medium blue hues, as exemplified in this ring’s faceted center stone. The wreath-like diamond surround not only serves to deepen and enrich the glorious blue of the center stone by contrast, but the white diamonds dance with a light show that is soft and dazzling, working together in such a way as to emphasize the qualities of each other so beautifully.

Size US 6.25, can be resized. Center oval sapphire of Ceylon origin with no indication of thermal treatment (unheated), weighing 19.28 carats, certified by AGL. Accented by 32 rose-cut diamonds and 4 baguette-cut diamonds, weighing approx. 3.00 carats total; estimated G color, VS clarity. Overall weight approx. 14.31 grams, made in platinum. Circa 2019.
