1.54 Ct. Bi Color / Parti Sapphire from Tanzania

This listing describes a single, transparent 1.54 carat oval shape bi color sapphire, presented and graded by The Natural Sapphire Company, with exact dimensions of 6.94 by 6.02 by 4.25 millimeters. The stone is faceted using a mixed brilliant cut, combining a faceted pavilion with a brilliant oriented crown, and it exhibits an intense color intensity with a distinct parti color character. Clarity is graded as very slightly included, evaluated at eye level, which means that inclusions are minimal and do not detract from the overall appearance when viewed without magnification. The polish on this gem is excellent, and there has been no enhancement applied, underscoring its natural and unaltered state. The sapphire is sourced from Tanzania, a region noted for producing parti and bi color sapphires with complex and appealing color zoning.

From a gemological perspective, the mixed brilliant cut and the transparent body contribute to lively light performance, producing defined facet reflections and measured scintillation across the crown. The bi color nature of the sapphire manifests as areas of differing hue and tone, which interact with the mixed brilliant faceting to produce shifting visual interest as the stone or the light source moves. The intense color intensity supports both strong saturation in localized areas and refined transitions between tones, resulting in a visually balanced appearance rather than abrupt contrasts. The very slightly included clarity grade allows for comfortable viewing without concerns about visible surface reaching fractures, and the excellent polish maximizes the stone to metal light return when set, preserving both brightness and delineation of the parti color pattern.

This sapphire is well suited to serve as a striking gift for someone special, offering a combination of individuality and classical gem proportions. At 1.54 carat and in an oval outline, the stone provides a generous presence without being oversized, making it adaptable to a variety of jewelry settings from a center stone in a ring, to a pendant, to accent pieces in a bespoke design. Its untreated condition and Tanzanian origin lend provenance and narrative to the gift, attributes that often carry sentimental weight for recipients who value natural gemstones with clear documentation. The mixed brilliant cut ensures the gem will perform well in light, while the parti color character makes each viewing experience subtly different, a quality that tends to resonate with recipients who appreciate one of a kind pieces.

Practical considerations for ownership and presentation are straightforward. As a corundum species sapphire, the stone has inherent durability for everyday wear in standard fine jewelry settings, and the excellent polish and faceting reduce the likelihood of surface wear affecting optical performance. Routine care involves gentle cleaning with warm water and mild soap, followed by drying with a soft cloth, and occasional professional inspection of the setting to confirm secure mounting. The Natural Sapphire Company can provide additional images, facet maps, and setting recommendations to assist in choosing an appropriate mount that highlights the stone color divisions while protecting the integrity of the gem. This sapphire combines measured gemological quality with an evocative parti color expression, presenting a refined and thoughtful option for a meaningful gift.
