1.48 Ct. Bluish Green Sapphire from Tanzania

One of the most captivating offerings from The Natural Sapphire Company is this transparent 1.48 carat cushion shape bluish green sapphire, a gem that combines rare natural color, precise proportions, and uncompromised finish. Measuring 6.48 by 5.44 by 4.23 millimeters, this stone sits in an ideal size range for both classic and contemporary jewelry applications, and its proportions highlight the careful cutting choices made to preserve weight while maximizing optical performance. Originating from Tanzania, this sapphire is free of enhancement, a characteristic that immediately sets it apart from many market alternatives, because untreated sapphires with intense natural color and excellent polish command a distinct premium for authenticity and long term value. The clarity has been evaluated as slightly included at eye level, which is common for natural stones of this character and does not diminish the gem in daily wear, because the inclusions are small enough that they do not interrupt the flow of light through the pavilion, and in many cases they add a fingerprint of identity that collectors appreciate.

At the heart of this sapphire is its mixed brilliant cut, a geometric faceting scheme that has been consciously executed to produce maximum light play. The mixed brilliant cut combines the scintillating performance of brilliant faceting on the crown, with step or modified pavilion facets that return light in a dynamic and lively manner, allowing a balance of sparkle and depth. The cushion outline gives a soft, elegant silhouette, while the faceting geometry creates a beautiful interplay of flashes, contrasts, and color zoning that changes as the gem moves. Compared to stones cut only as a step cut or as a traditional old mine cushion, this gem offers more scintillation and a broader palette of reflected colors, because the small, well aligned facets break light into more discrete flashes, increasing both brightness and perceived size. The excellent polish amplifies this effect by ensuring that every facet surface is smooth and reflective, so that light is not scattered by surface abrasion, and so that the intense bluish green hue is seen with clarity and vitality from many viewing angles.

When you compare this sapphire to other options commonly available on the market, several competitive advantages become clear. Many sapphires at similar price levels are subject to heat treatment or clarity enhancement, processes that can improve color and remove visible inclusions, but which alter the natural state of the stone and reduce rarity. This Tanzanian sapphire is untreated, which enhances its desirability for buyers who value provenance and geological integrity, because untreated stones often appreciate more in value over time given their scarcity. In terms of cut, stones that are uniformly faceted for weight retention rather than for optical performance can appear dull or heavy, even when they carry good color, whereas this mixed brilliant cushion has been sculpted with light return as the priority, creating an immediate visual impact that stands out in a collection. The slightly included clarity grade is actually an advantage for many customers, because the inclusions are small and positioned so that they do not compete with the intense color, and because a perfectly eye clean sapphire of this color and size, with no enhancement, would typically command a much higher price. The combination of intense color intensity, untouched origin, and superior polish makes this gem a rare value proposition when compared to heat enhanced stones, synthetic alternatives, or even less well cut natural sapphires.

For practical considerations and design guidance, this sapphire adapts gracefully to a variety of settings that will further accentuate its geometric faceting and color. Settings that allow light to enter the pavilion, such as four or six prong mounts with an open gallery, will enhance brilliance, because light can penetrate and be reflected back through the crown faceting. A halo of small brilliant cut diamonds will increase perceived size and add scintillation contrast, while a simple solitaire in platinum or white gold will emphasize the cool bluish green tone, and a warm metal like yellow or rose gold will create a striking contrast that can make the green notes appear richer. For an engagement piece or a signature ring, the mixed brilliant cut will sparkle continuously with movement, offering a lively presence on the hand that is more engaging than a plain step cut, and at 1.48 carats this sapphire provides a perfect balance between everyday wearability and visible impact. At The Natural Sapphire Company we can provide expert mounting advice and bespoke design options that honor the stone, and our experience with Tanzanian material helps ensure that each selection reflects both geological authenticity and aesthetic excellence. If you are seeking a stone that is unique in color, honest in origin, and exceptional in optical design, this cushion shape bluish green sapphire represents a superior choice in quality, value, and personality.
