0.45 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents one transparent 0.45 carat oval blue sapphire, supplied by The Natural Sapphire Company, with precise dimensions of 5.01 x 4.02 x 2.98 mm. The stone is fashioned in an oval outline with a mixed brilliant cut, resulting in a balance of scintillation and color play. Color assessment registers as intense, and polish is graded excellent, producing crisp facet junctions and lively reflections under direct and diffuse light. Clarity is described as very slightly included when evaluated at eye level, a practical designation that reflects small internal characteristics that do not materially interfere with the gem s overall transparency and visual performance. Enhancement is limited to heat treatment, a stable and industry standard procedure used to enhance color uniformity, and the sapphire s origin is Ceylon, Sri Lanka, a source long associated with appealing blue tones and consistent material quality.

The oval shape and the specific dimensions of this sapphire make it especially adaptable for custom jewelry work, offering designers predictable proportions that simplify setting decisions while maintaining a strong presence on the finger or in a pendant. The length to width relationship inherent in a 5.01 by 4.02 mm oval delivers a slightly elongated silhouette that can visually lengthen the finger when set as a center stone in a ring, or provide a refined focal point when mounted horizontally in an east west style. At 0.45 carat the gem sits in a size range that is ideally suited for delicate solitaire rings, understated three stone compositions, bezel set pendants, and fine stud or drop earrings, while also pairing well as a highlighted accent in more complex cluster or halo designs. The modest table size and proportional depth, recorded at 2.98 mm, permit both low profile bezel settings for everyday wear and prong mounts that maximize light return when a more open setting is preferred.

From the bench jeweler s perspective the mixed brilliant cut presents practical advantages in handling and setting, and it supports attractive optical performance without compromising color saturation. The cutter s approach to facet arrangement enhances internal reflections while preserving the intense blue that characterizes Ceylon material, and the excellent polish reduces surface light loss and improves overall brilliance. The clarity grade of very slightly included at eye level indicates that inclusions are minor and generally confined to areas that do not interrupt the gem s face up appearance, which simplifies the choice of setting since the inclusions will not typically be visible to the unaided eye in normal wear. The combination of compact dimensions, reliable proportions, and robust facet symmetry makes this sapphire a straightforward candidate for matched pair work or for use as a calibrated center in designs where multiple stones must align precisely.

Practical considerations for design and long term wear include the sapphire s natural durability, treatment stability, and aesthetic versatility. As a corundum species with a hardness of nine on the Mohs scale, this sapphire withstands everyday abrasion far better than most colored gemstones, which supports the selection of more open settings when desired, without unduly increasing the risk of damage. Heat treatment is stable under normal wear and maintenance, and standard jewelry cleaning and ultrasonic procedures are generally acceptable, subject to final setting configuration. The Ceylon origin contributes a market recognized blue that performs attractively in yellow, white, and rose metal palettes, enabling designers to tailor contrast and warmth by metal choice. The Natural Sapphire Company offers design consultation and technical guidance for secure mounting options, including recommended prong profiles and bezel wall heights that accommodate the stone s depth and protect its girdle during routine use. For clients seeking a refined, long lasting custom piece, this 0.45 carat oval Ceylon sapphire provides a well balanced combination of size, shape, and optical quality that integrates readily into both contemporary and traditional jewelry compositions.
