2.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent, oval shape gem weighing 2.40 carat, with precise dimensions of 7.84 x 6.74 x 4.87 mm, a mixed brilliant cut, and an intense blue color intensity. The stone is graded as very slightly included when evaluated at eye level, indicating minimal visible inclusions that do not distract from the gem s overall appearance, and it has an excellent polish which enhances surface luster and light return. Origin is Ceylon Sri Lanka, a provenance with a long history of producing some of the world s most desirable blue sapphires, and the stone has undergone a standard heat treatment to stabilize and enhance its color and clarity. At The Natural Sapphire Company we inspect each gem under controlled lighting and magnification, and we report factual grading and treatment information so that educated buyers can make informed decisions.

From a gemological perspective the intense blue hue of this sapphire is created by trace amounts of iron and titanium within the corundum crystal structure, and achieving such a saturated, uniform color in a gem of this size is uncommon. Many sapphires that show deep, saturated color are found in small sizes where uniform color can be preserved, while larger rough commonly exhibits color zoning or diluted tones that require cutting tradeoffs. A 2.40 carat sapphire with this level of chroma is therefore rarer relative to more common smaller stones and to larger material with weaker saturation. The Ceylon origin is important because Sri Lankan sapphires are prized for their lively, vivid blues with a slightly lighter overtone compared with some Kashmir or Burmese examples, and this specimen displays a rich intensity that reads as classic Ceylon blue while leaning toward a deeper, more saturated presentation than is often encountered in stones at this weight.

Clarity and cutting are two critical elements for buyers focused on optical performance and long term value, and this stone s very slightly included clarity grade evaluated at eye level means that inclusions are minimal and generally not visible without magnification or careful inspection. For an educated buyer this balance between clarity and color is ideal, because sapphires often trade off perfect clarity for richer color saturation, and this gem maintains both pleasing transparency and a powerful hue. The mixed brilliant cut combines pavilion faceting designed to maximize light return with crown facets that deliver controlled dispersion, resulting in a gem that shows lively internal brilliance and even color distribution across the face up view. The dimensions produce a strong face up presence in a ring setting, and the slightly deeper pavilion contributes to color depth without sacrificing sparkle, while the excellent polish ensures crisp facet junctions and a bright surface luster that will perform well under varied lighting conditions.

From a value and usage standpoint this sapphire stands out for several reasons that will appeal to informed purchasers. The combination of 2.40 carat weight, intense blue saturation, transparent material, and Ceylon origin is a configuration that is less frequently available on the market, supporting both desirability and relative scarcity. Heat treatment is the only enhancement disclosed, and this is a widely accepted and stable treatment that improves color and clarity while remaining permanent under normal wear conditions, a fact that professional buyers understand and accept when treatment is fully disclosed. Corundum s inherent hardness and toughness make sapphire an excellent choice for everyday jewelry such as engagement rings, pendants, and signet pieces, and the stone s dimensions and cut make it adaptable to a variety of settings including classic solitaire, halo, or bezel montures. At The Natural Sapphire Company we emphasize transparent grading, careful sourcing, and precise cutting, and we are available to advise on setting styles that will maximize both the gem s optical performance and longevity. For collectors and investors looking for a Ceylon sapphire that combines rarity, aesthetic appeal, and practical durability, this 2.40 carat oval is a compelling option.
