1.69 Ct. Bluish Green Sapphire from Tanzania

This sapphire is a finely proportioned, transparent 1.69 carat emerald cut bluish green sapphire, with exact dimensions of 7.46 x 5.41 x 4.18 millimeters, offered by The Natural Sapphire Company. The stone displays a vivid color intensity that immediately separates it from paler examples, and its emerald cut presents a broad, elegant table and step facets that emphasize its depth of hue. The clarity grade is very slightly included, evaluated at eye level, indicating that any internal features are minimal and do not distract from the gem when set. The polish is excellent, producing clean facet junctions and a smooth surface that enhances the stone s ability to reflect light. Importantly for informed buyers, this sapphire has no enhancement, meaning it is in its natural, untreated state, and it is documented as originating from Tanzania, a region known for producing distinctive, richly colored sapphires.

From a gemological perspective, the emerald cut is particularly well suited to this stone because its linear facets and expansive table reveal both the richness of the bluish green color and the high degree of transparency. The step facet arrangement tempers excessive brilliance in favor of a refined, velvety flash that highlights color nuances across the stone. Because the clarity is very slightly included at eye level, the emerald cut was a deliberate choice, as step cuts tend to display clarity rather than mask it, which speaks to the quality of this rough material prior to cutting. The excellent polish aids in light return without introducing surface abrasion, and the absence of enhancement adds measurable value for collectors who prioritize natural state material. Origin matters in the trade, and Tanzania s deposits have produced sapphires with a captivating range from deep teal to bluish green, attributes that seasoned buyers recognize and prize.

When set in jewelry, this sapphire s vivid bluish green will command attention in any metal and design, while responding differently to contrasting environments in ways that can be creatively exploited. In white metals, the blue component will read as a cooler teal, producing a crisp, modern look that pairs beautifully with diamond accent stones. In yellow or rose gold, the green aspects will appear warmer and more luminous, creating a rich, vintage aesthetic. The emerald cut lends itself to solitaire settings that celebrate clean geometry, to halo settings that introduce scintillation without overpowering color, and to bezel mounts that protect the girdle for everyday wear. For a wearer who wants maximum color impact, low profile prong work will allow light to enter the pavilion freely, while for those seeking durability, a bezel can offer added security. Care for this sapphire is straightforward, with routine cleaning in warm soapy water and a soft brush recommended, and professional inspection advised if the piece is to be worn daily. At The Natural Sapphire Company we emphasize provenance, treatment disclosure, and precision grading, and we are pleased to provide further gemological details and photography on request, so that educated buyers can make an informed purchase decision that balances aesthetic appeal, rarity, and long term value.
