5.44 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified Blue 5.44 carat radiant shape blue sapphire is a standout gem for the discerning buyer, offering a combination of size, color, and provenance that is rare in today s market. The stone measures 10.42 x 8.98 x 6.19 mm, it is transparent, and it has been cut in a faceted radiant style that maximizes both face up presence and light performance. The color displays an intense blue saturation typical of fine Ceylon sapphires, with a lively balance of depth and vibrancy that reads beautifully in daylight and in artificial light. Clarity is graded as slightly included when evaluated at eye level, which is consistent with natural sapphires of this quality and size, and which has minimal impact on the stone s visual appeal and structural integrity. The polish has been graded excellent, so the facets present crisp reflections and a lively play of brilliance. The sapphire has been heat treated, a widely accepted and stable enhancement in the trade that improves color saturation and clarity without compromising the gem s durability. The documented origin is Ceylon Sri Lanka, a provenance prized by collectors and experienced buyers for its historical association with some of the world s most desirable blue sapphires. The Natural Sapphire Company presents this gem with full transparency about its grading and treatment, giving educated buyers the factual basis to assess both aesthetic and investment attributes.

The radiant cut is particularly well suited to custom jewelry work, because it combines the light return of brilliant style facets with the clean outline and depth distribution of step facets. The result is a gem that reads larger than its weight might suggest, with strong scintillation and a broad table that showcases the intense blue color across the face of the stone. At 10.42 mm by 8.98 mm, this sapphire is an ideal center stone for a wide range of custom designs, from classic solitaires to vintage inspired halo settings, three stone rings, or bold cocktail pieces. The rectangular radiant outline also offers design flexibility, as it can be oriented vertically for an elongating effect on the finger, or set horizontally for a contemporary look in a pendant or bracelet. The slightly included clarity grade means inclusions are present but not intrusive to the naked eye, allowing for secure setting options such as four or six prong heads or bezel settings when additional protection is desired. The excellent polish and precise faceting ensure predictable light performance after setting, which is critical when working with bespoke mounting geometries and accent stones.

For custom design considerations, the size and shape of this sapphire make it exceptionally versatile. In an engagement ring context, the stone s dimensions pair well with tapered baguette diamonds, round brilliant side stones, or a full halo to enhance apparent size and contrast color. The intense blue of the sapphire pairs beautifully with both cool toned metals like platinum and 18 carat white gold, which emphasize brilliance and contrast, and warmer metals such as 18 carat yellow gold or rose gold, which enrich the perceived depth of the blue and create a striking, vintage inspired palette. The radiant cut s faceting pattern allows for confident gem setting, with even pavilion depth and table proportions that minimize unexpected light leakage. Because the gem has been heat treated it is stable for all common jewelry settings and for normal wear, while its natural hardness places it among the most durable gemstones for everyday jewelry. Routine care recommended for heat treated sapphires is gentle cleaning with warm soapy water and a soft brush. Professional inspection and maintenance are advisable for any prong or bezel settings to ensure long term security.
