16.35 Ct. Orange Cabochon Sapphire from Ceylon (Sri Lanka)

This 16.35 carat cushion shape orange sapphire from The Natural Sapphire Company is a rare and memorable offering, with dimensions of 16.12 x 12.85 x 7.01 mm, cabochon cut, and a translucent body that brings a warm, honey like glow to life. Compared to the more common faceted sapphires and smaller accent stones, this piece reads as a true center stone because of its size and presence. The intense color intensity and excellent polish produce a deep, even orange that is more evocative and wearable than many synthetic or heavily altered alternatives on the market. Where faceted stones rely on light return and sparkle, this cabochon excels by presenting a uniform, luminous surface that flatters contemporary and vintage settings alike, and the very slightly included clarity grade as evaluated at eye level means it retains visual purity while reflecting natural character. Origin Ceylon Sri Lanka is a mark of provenance that collectors seek, and the heat treatment enhancement used here is a standard, stable process that enhances color without compromising durability, a clear advantage over diffusion or glass filled options that can be fragile or less reliable over time.

When comparing this orange sapphire to competing orange gems such as spessartite garnet, fire opal, or treated topaz, a sapphire stands out for long term value and resilience. On the Mohs hardness scale sapphire ranks at nine, which is markedly harder and more wear resistant than garnet and opal, making it a better choice for rings and pieces intended for daily wear. Many orange alternatives can be striking at first glance, but they often lack the combination of color saturation, clarity, and toughness that this Ceylon sapphire provides. In addition, the size of this stone at over sixteen carats is exceptional for orange sapphires, and that scale alone elevates its rarity and collectible appeal. The cabochon form also offers design opportunities that faceted stones cannot replicate, delivering a smooth tactile quality and a soft, internal glow that adds depth to the color, especially when set in warm metal tones. From a value perspective, heat treated natural sapphire, responsibly sourced and expertly finished, typically outperforms mass produced or heavily treated alternatives on both price retention and market desirability.

For buyers considering a distinctive statement or an heirloom piece, this sapphire is particularly compelling, and The Natural Sapphire Company stands behind its selection and presentation. The excellent polish enhances the cabochon silhouette and ensures that light skims across the dome in a flattering way, while the translucence allows a subtle play of internal color that changes with orientation and lighting, giving the gem a living quality that many faceted orange stones cannot match. Design recommendations include a bezel or high cabochon setting to protect the surface and highlight the stone's luminous color, or a custom pendant where the smooth dome can catch ambient light and warm the wearer. For collectors and designers who value authenticity, this gem offers both aesthetic superiority and sensible practicality, since natural Ceylon origin, visible but minor inclusions, and conventional heat treatment are all features that indicate a responsibly traded, stable gem rather than a laboratory modified or fragile simulant. If you are comparing options across the market, consider the combination of size, color intensity, polish, origin, and durability that this cabochon orange sapphire delivers, and contact The Natural Sapphire Company for any additional details, viewing options, or bespoke setting ideas.
