1.05 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This gemstone is a beautifully transparent 1.05 carat blue sapphire, presented in a classic oval shape with precise dimensions of 6.82 x 5.53 x 3.19 mm, and a mixed brilliant cut that combines step and brilliant faceting for both depth and scintillation. The stone displays vivid color intensity, and an excellent polish that enhances surface luster and light return. Its clarity is graded as very very slightly included when evaluated at eye level, meaning the stone reads very clean to the naked eye while retaining natural internal characteristics that confirm its identity and origin. Enhancement by standard heat treatment has been applied, a widely accepted and stable practice in sapphire finishing, and the origin of this material is Ceylon, Sri Lanka, a historic source renowned for producing highly sought after cornflower to vivid blue sapphires.

From a gemological perspective, the mixed brilliant cut used on this oval sapphire is an intelligent choice for maximizing visual performance in a gem of this size and shape. The mixed cut blends a faceted pavilion of step facets beneath a crown with brilliant facets, balancing depth and reflection, which helps to preserve color saturation while promoting scintillation. At 1.05 carat and with the given dimensions, the pavilion depth and crown angles have been optimized to provide a generous face up appearance, so the stone looks proportionally larger than many round stones of similar carat weight. The very very slightly included clarity grade, assessed at eye level, indicates that inclusions are minimal and not distracting, ensuring the sapphire will read as clean in most jewelry settings, while still presenting natural features that informed buyers associate with authenticity. The excellent polish is a key factor for mounting, because sharp facet junctions and a smooth surface increase brilliance and make the stone easier to set without losing optical performance.

This sapphire is particularly well suited to custom jewelry because the oval outline combines classical elegance with practical versatility, and the dimensions are ideal for a wide range of bespoke designs. The 6.82 x 5.53 mm face up area offers a pleasing elongation that flatters fingers and creates a visual impression of length when set in rings, while remaining comfortable for daily wear. For engagement rings, an east west orientation can accentuate the oval profile for a contemporary look, while a traditional north south orientation with four or six prongs will emphasize symmetry and durability. The mixed brilliant cut and vivid color intensity respond exceptionally well to open prong settings, halo designs in which smaller diamonds can frame and intensify the central blue, and bezel settings that highlight the stone when a sleeker, more protective mount is desired. In pendant or drop earring applications, the oval shape maintains a graceful silhouette that swings and catches light, and the moderate thickness at 3.19 mm gives enough depth to facilitate secure prongs or a light bezel without overwhelming the profile.

For the educated buyer who values both aesthetic and technical quality, this sapphire represents a balanced investment in beauty and wearability. Its Ceylon origin is significant, because Sri Lankan sapphires often present a bright, vibrant blue that sits between the softer cornflower tones and the deeper royal blues of other sources, making them highly versatile for pairing with different metals. Heat treatment, when properly disclosed as it is here, stabilizes and enhances the stone while being a widely accepted industry practice that does not diminish long term durability. The very very slightly included clarity grade supports resale and certification, since microscopic or minor internal features are expected in natural stones and help gemological labs confirm origin and natural formation. At The Natural Sapphire Company we emphasize transparent disclosure, and this sapphire has the technical attributes that custom jewelers and discerning clients seek, including ideal proportions for faceting, a high polish grade that improves setting outcomes, and a vivid color that translates well into photographic and in person presentations. For custom work we recommend reviewing setting mock ups and metal choices in person or via detailed CAD imagery, because the way the metal reflects into the pavilion can subtly shift perceived color, and because the oval form offers multiple stylistic directions to suit an individual design brief.

Care and long term stewardship are straightforward, because sapphires are among the hardest gemstones used in jewelry, and this 1.05 carat Ceylon stone will tolerate daily wear when set securely. Routine cleaning with warm soapy water and a soft brush will maintain brilliance, and periodic inspections of prongs or bezels will protect the stone from accidental loosenings, especially in more active wearers. When commissioning a custom piece, consider matching color temperature with white gold for contrast, yellow gold for warmth, or platinum for a contemporary, durable setting that complements vivid blue tones. For clients seeking certification, independent gemological reports that confirm origin, treatment, and dimensions will reinforce provenance and value. If you prefer a bespoke design consultation, our team at The Natural Sapphire Company can advise on mounting styles, complementary accent stones, and metal finishes that enhance the sapphire s unique optical properties, ensuring the finished piece reflects both the gem s technical excellence and your personal aesthetic.
