1.17 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

One transparent 1.17 carat emerald cut bi color sapphire, measuring 6.77 by 5.53 by 3.16 millimeters, presents a refined combination of clarity, color, and proportion. The stone shows a vivid color intensity that reads as deep blue with a subtle secondary hue that can read differently with changes in light and orientation. Cut to the emerald shape, the faceting emphasizes a broad table and step facets that allow the gem to present a calm, even color field while also revealing internal character across the pavilion. Clarity is graded as very slightly included when evaluated at eye level, indicating that any inclusions are minimal, well centered within the stone, and do not detract from the visual appeal when set in jewelry. The polish is excellent, producing crisp facet junctions and strong surface luster, and the sapphire has not been subject to any enhancement, a condition that preserves its natural state and contributes to its long term stability and value. Origin is Ceylon in Sri Lanka, a classic source known for producing high quality sapphires with clean color and consistent crystal growth patterns.

The emerald cut format is a considered choice for a stone with bi color character and very slight inclusions at eye level, because the step facets and elongated outline control the way color zones appear, allowing a wearer to show either side of the hue depending on how the gem is set and oriented. The dimensions of 6.77 by 5.53 by 3.16 millimeters provide balanced face up presence for a 1.17 carat gem, suitable for ring heads, solitaire pendants, and refined three stone settings. Excellent polish complements the gem architecture, maximizing the available light return from the broad facets and enhancing the perception of depth and saturation. The lack of enhancement means the sapphire retains original diffusion of trace elements and internal zoning, factors that appeal to connoisseurs and collectors who value natural provenance and geological authenticity. The Ceylon provenance adds an additional layer of interest, as Sri Lankan sapphires are often sought for their clarity and lively color, attributes that are evident in this example.

As a generational heirloom, this sapphire has the material and aesthetic qualities that support long term stewardship and legacy. Corundum is second only to diamond in hardness with a Mohs hardness of nine, which confers strong resistance to abrasion and surface wear for daily use when properly set and maintained. The absence of heat or other treatments reduces the likelihood of color instability or unexpected reactions to routine cleaning, preserving the stone in its original state for successive owners. To create an heirloom piece that endures, consider commissioning a robust mounting that protects the girdle and corners, for example a four or six prong head with protective bezel accents, or a low profile pavilion guard in a custom ring design. Documentation from The Natural Sapphire Company that details the gem specifications, origin, and treatment status will form part of the historical record for the piece, and professional appraisal and registration with an insurer will protect its monetary value.

Beyond physical durability, the intangible attributes of provenance, natural state, and refined cut support intergenerational appeal. The emerald cut provides a timeless, architectural silhouette that adapts to changing styles, and the bi color character gives the stone a living quality that will invite attention and conversation from successive generations. Simple maintenance, periodic professional inspection, and sensitive repairs when needed will ensure that settings remain secure and that the gem continues to display its vivid color and excellent polish. The Natural Sapphire Company can assist with recommended setting designs, conservation grade mounting techniques, and documentation practices that convert a single exceptional sapphire into a curated family treasure. When assembled with care, this 1.17 carat Ceylon sapphire will perform as a durable wearable object, an authenticated artifact, and a meaningful heirloom to pass forward.
