2.03 Ct. Spinel from Tanzania

This exquisite heart shaped blue spinel weighs 2.03 carats and measures 6.96 x 8.27 x 5.10 mm, a size that balances presence with wearability, and it arrives to you as a transparent gem with dark color intensity and a mixed brilliant cut. Originating from Tanzania, this stone is fully natural and untreated, no enhancement, which is an important consideration for an educated buyer seeking verifiable provenance and intrinsic value. The mixed brilliant cut has been executed to accentuate the stone’s depth and light return, while the heart shape introduces a classic romantic silhouette that is both wearable and collectible. The clarity grade is slightly included when evaluated at eye level, a realistic and honest assessment that allows the gem to remain visually appealing while retaining natural character, and the overall polish is recorded as excellent, which speaks to the high level of lapidary skill that transformed the rough into this refined, finished gem.

When you examine this spinel, the interplay of cut and finish is immediately evident, the precision of the mixed brilliant faceting maximizes scintillation while preserving the saturation of the deep blue tone. Mixed brilliant cuts combine the best properties of brilliant faceting with carefully considered pavilion geometry, creating a balance between sparkle and color retention, and in this heart shaped example, that balance is exceptional. The excellent polish eliminates surface irregularities that can scatter light poorly, so each facet edge reads clean and crisp, and the result is a stone that appears to glow from within when viewed from multiple angles. While the clarity is slightly included at eye level, these natural inclusions do not detract from the gem when set, because the cutter positioned facets strategically to mask and minimize the visual impact of internal features, this is a hallmark of skilled cutting that enhances the perceived purity and depth of the stone without altering its natural identity.

For the discerning buyer, several technical attributes increase this spinel’s appeal and long term value. Spinel is notably robust, with a hardness around eight on the Mohs scale, which makes this heart shaped gem suitable for a range of jewelry applications including rings and pendants that are intended for regular wear. The size at just over two carats places it in a weight class that is both attractive for bespoke design and significant enough to be considered an investment quality stone by collectors. The Tanzanian origin carries geological interest and growing market recognition, as East African spinels have produced notable finds and desirable hues, and the fact that this piece is untreated means its color and luster are entirely natural, a premium attribute in the marketplace. Dark color intensity in blue spinel can command higher prices when transparency and cut quality are maintained, because the saturation communicates rarity and depth, and because the mixed brilliant cut in this gem preserves both sparkle and color depth, it performs well under various lighting conditions.

From a practical perspective, the gem’s heart outline and proportions, combined with the excellent polish, create an impression of flawless finishing work even though the stone retains natural inclusions, and this quality of finish is what allows the gem to present beautifully from every angle. When set in a well designed mounting, the heart shape will read clearly on the hand or at the throat, and the mixed brilliant faceting will give flashes of blue and lighter reflective accents that animate the stone with movement. We at The Natural Gemstone Company ensure that each gem is photographed and documented so buyers can assess proportions, color and facet performance prior to purchase, and we are available to advise on settings that protect the stone and maximize visual impact, for example a partial bezel to shelter the apex and lobes or a four prong mounting to expose light return while securing the piece. With proper setting and routine care this Tanzanian blue spinel will retain its beauty and deliver elegant performance for years, making it an excellent choice for someone who values natural provenance, thoughtful cutting, and enduring wearable quality.
