1.86 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.86 carat oval shape blue sapphire, measuring 8.13 x 6.75 x 4.13 mm, offers a rare combination of size, color, and clarity that sets it apart from most market offerings. This Ceylon origin gem displays a vivid color intensity that is unusually deep for Sri Lankan material, and the mixed brilliant cut brings exceptional fire and life to every facet. The clarity grade is very slightly included when evaluated at eye level, which means the stone is effectively eye clean and presents a pure window of color without the visual distractions common in many commercial sapphires. The excellent polish enhances surface luster, and the heat treated enhancement is a standard, stable practice that unlocks the stone true potential without compromising long term stability. At The Natural Sapphire Company we prioritize stones that combine beauty and integrity, and this sapphire exemplifies that commitment, offering a distinct alternative to both smaller, weaker colored stones and larger stones with dull or cloudy appearance.

When compared to other blue sapphires on the market, this 1.86 carat oval stands out for its proportional balance and uncommon hue. Many Ceylon sapphires are prized for their lighter cornflower tones, but vivid deep blue examples in this size are less frequently encountered, creating rarity by both color intensity and carat weight. This piece avoids the two common extremes of the market, which are tiny vivid stones that lack presence, and large stones that show heavy zoning or inclusions. The oval shape with dimensions of 8.13 x 6.75 x 4.13 mm sits in an ideal range for elegant ring designs, offering enough table area to show the gem color while maintaining a comfortable profile on the finger. The mixed brilliant cut is intentionally used to maximize scintillation and to distribute color evenly, providing a lively face up appearance that compares favorably with step cuts and traditional mixed cuts that often fail to marry depth and brightness as successfully.

Value wise, this sapphire presents a compelling proposition compared with other options that either sacrifice beauty for size, or color for clarity. Heat treated sapphires are industry standard and represent excellent value when the treatment is straightforward and durable, as with this stone. The combination of vivid color intensity and eye level clarity means buyers achieve a strong visual impact without paying the premium reserved for fully untreated stones that are also flawless. In practical terms this sapphire delivers the look of a higher price tier while maintaining sound market value, making it a smart choice for both connoisseurs and clients seeking a special everyday jewel. Origin matters in the trade, and Ceylon sapphires have long been recognized for their appealing tonality and lively character, but finding a Ceylon stone with this degree of saturation and eye cleanliness at 1.86 carat is uncommon, which elevates its desirability and long term collectibility.

For design and ownership considerations, this sapphire adapts beautifully to classic solitaire rings, halo settings that enhance perceived size, or bespoke pieces where the stone color remains the focus. The proportions of 8.13 x 6.75 x 4.13 mm allow for secure bezel or prong settings while preserving the optical performance that makes the gem sing. Collectors seeking rare color and strong face up presence will find this stone a rare find, and bespoke clients will appreciate the way the mixed brilliant cut adds lively sparkle without overstepping the elegant, deep blue character of the gem. The Natural Sapphire Company stands behind our description and grading practices, and we encourage comparison with other listings in the market to appreciate how this sapphire combines proportion, polish, and vivid color in a way that few comparable stones do. For anyone seeking a high impact, rare Ceylon blue sapphire with solid value and exceptional visual appeal, this 1.86 carat oval is an outstanding choice, and our team is available to provide additional images, setting suggestions, and certification details to support a confident purchase.
