1.35 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent oval blue sapphire weighs 1.35 carat and measures 7.74 x 6.02 x 3.45 mm, presenting a classic and highly versatile oval footprint for custom jewelry. The gem has been expertly fashioned with a mixed brilliant cut, combining a faceted pavilion and a proportioned crown that optimizes light return while preserving weight for a substantial face up presence. Clarity is graded as eye clean when evaluated at eye level, offering uninterrupted color and brilliance to the unaided observer. Color intensity is vivid, yielding a saturated blue that reads lively across varied lighting conditions, and the stone displays an excellent polish that enhances surface luster and reflective contrast. Enhancement is heat treated, a well established and permanent practice that improves color and clarity without compromising stability. The origin is Ceylon Sri Lanka, a source long esteemed for producing sapphires with a resonant blue character and attractive saturation. This sapphire is presented by The Natural Sapphire Company, where provenance, cutting quality, and accurate grading are core to our selection.

Understanding how cut, clarity, and origin translate into practical value will help a collector or a bespoke buyer assess suitability for a specific design. The mixed brilliant cut on this oval creates a lively balance between sparkle and color depth, enabling the vivid blue to remain strong while facets return bright pinpoint highlights. Eye clean clarity means the stone will perform exceptionally in open settings such as prong mountings and halos because inclusions are not visible to the naked eye, which preserves both visual purity and resale value. Heat treatment is a standard, documented enhancement that stabilizes color and is widely accepted by gemological laboratories and serious buyers, and the Ceylon Sri Lanka provenance adds a desirable narrative because stones from this region are known for their clear, vivid blues that appeal to sophisticated tastes. The excellent polish ensures crisp facet junctions and minimal surface disturbance, which is important for custom work where close viewing under lights and loupe is common during design approval.

From a design perspective this sapphire is ideal for custom jewelry because the dimensions and oval shape offer significant design latitude while keeping a refined silhouette. At 7.74 x 6.02 mm the gem sits in a size range that is comfortable for a central solitaire ring, an elegant pendant, or a focal element in a fine pair of drop earrings, providing a strong visual impact without overwhelming delicate settings. The modest depth of 3.45 mm combined with the mixed brilliant cut gives a well balanced table and pavilion relationship that suits both bezel and prong settings, and the vivid color will hold its presence even when surrounded by diamonds in a halo configuration or paired with color accent stones for contrast. For engagement rings this sapphire offers excellent daily wear characteristics, thanks to corundum hardness and a stable heat treatment, and the oval outline flatters many finger shapes and allows creative orientations such as east west setting or elongated east west design elements that visually lengthen the finger.

When commissioning a bespoke piece The Natural Sapphire Company can provide guidance on mounting options that maximize the sapphire visual return while protecting the stone. A clean oval such as this will take a variety of metal choices gracefully, from warm yellow gold that adds contrast to cool platinum that emphasizes the blue saturation, and our bench can recommend prong counts and bezel profiles that balance security with light performance. We document source and treatment and can arrange independent grading on request for buyers who require formal certification as part of their purchase. This sapphire represents a rare combination of vivid color, eye clean clarity, and a practical oval size, making it an excellent candidate for a discerning client seeking a bespoke engagement ring or a refined personalized piece that will be worn and treasured for years.
