0.35 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes one transparent 0.35 carat oval blue sapphire offered by The Natural Sapphire Company, presented with precise dimensions of 4.53 by 3.82 by 2.37 mm. The gem exhibits a mixed brilliant cut that balances pavilion faceting with a carefully faceted crown, producing lively scintillation within a compact profile. Its color is reported as vivid in intensity, delivering a saturated and eye catching Ceylon blue that remains strong even in small proportions. Clarity is graded as very slightly included when evaluated at eye level, indicating that minor internal features are present but do not detract from overall appearance under typical viewing conditions. The surface finish achieves an excellent polish, aiding light return and maintaining crisp facet junctions. Enhancement is heat treated, a stable and widely accepted practice for improving tone and saturation in natural sapphires. The origin is Ceylon Sri Lanka, a source renowned for producing sapphires with pure, vivid blue coloration and excellent transparency.

The stone size and oval outline make this sapphire particularly well suited to custom jewelry applications where proportion and versatility are priorities. At 0.35 carat and with millimeter measurements slightly over four by three point eight, the gem reads as delicate when set alone, and as a refined focal point when paired with accent stones. The oval shape naturally elongates the visual axis, making it an attractive choice for slender engagement ring designs and for east west orientations that broaden design options. Its compact depth of 2.37 mm supports lower profile settings that sit comfortably for daily wear, while the mixed brilliant cut ensures lively sparkle that complements both open prong mountings and bezel settings. Designers will find the vivid Ceylon blue responsive to different metal choices, with cool white metals emphasizing brightness and warmer yellow tones enriching the stone body color. For halo and three stone configurations the stone size allows for proportional arrangements without overwhelming the overall aesthetic, and for multi stone pieces this sapphire can serve as either a tasteful center or a distinguished accent.

From a practical standpoint the combination of very slightly included clarity, excellent polish, and a durable corundum hardness makes this sapphire a reliable candidate for bespoke pieces that are intended for frequent wear. Heat treatment in this instance is permanent under normal wearing conditions, and it enhances visual attributes while preserving the natural origin and structure of the stone. When planning a custom mounting, consider settings that protect the girdle and pavilion given the shallow to moderate depth, and select prong profiles that secure the oval outline without obscuring the color zone. The Natural Sapphire Company can assist with recommendations for setting styles, metal selection, and proportion studies to ensure the stone performs optimally in its intended design. For makers and clients seeking a refined, small scale blue sapphire with authentic Ceylon provenance, this gem offers a balance of vivid color, precision cutting, and dimensions that make it exceptionally adaptable for rings, pendants, and matched earring pairs in custom jewelry work.
