2.56 Ct. Tanzanite from Tanzania

This 2.56 carat oval blue tanzanite is an exceptional example of refined gem quality, measuring 9.47 by 7.38 by 5.21 mm, presented in a mixed brilliant cut that balances scintillation and color saturation. The stone is transparent, with a clarity graded as very slightly included when evaluated at eye level, and it displays a vivid color intensity supported by an excellent polish. Enhancement heat treated, this tanzanite shows the classic deep blue violet that collectors seek, a hue produced by controlled heating which is an accepted and stable treatment in the trade. Origin Tanzania, this gem hails from the same geological source that has made tanzanite prized and rare since its discovery, and it has been selected and cut to maximize both the face up color and the internal light return, resulting in a gem that performs beautifully under varied lighting conditions.

From a gemological perspective this tanzanite offers attributes that an educated buyer will recognize and value. The mixed brilliant cut combines pavilion facets optimized for brilliance with crown facet arrangements that enhance the vivid color, producing lively sparkle while preserving the saturation that defines tanzanite desirability. The proportions yield an overall depth of approximately sixty two percent, a range that supports stable light return without sacrificing face up size, and the excellent polish ensures clean facet junctions and optimal surface reflectivity. Clarity graded as very slightly included at eye level means that inclusions are minor and do not distract from the gem when worn, which supports both aesthetic and resale considerations. The heat treatment disclosed is stable and industry standard for tanzanite, reducing brownish tones and revealing the split blue violet hues that make this gem so sought after. For the discerning collector, this combination of weight, cut, clarity, color, and polish places the stone in a category of pieces that function well as both wearable art and as a considered addition to a curated collection.

Ethical sourcing is central to how we present this gem at The Natural Gemstone Company, and we prioritize traceability and responsible partnerships at every step. The tanzanite originates from Tanzania, and we work directly with trusted partners who operate in the Merelani region and surrounding areas, promoting fair wages, safe working conditions, and local community investment. We require documentation of legal export and chain of custody whenever possible, and we support initiatives that minimize environmental impact through best practice mining techniques and rehabilitation where feasible. Our purchasing protocols favor miners and cutting houses who are transparent about their practices, and we engage with independent auditors and community stakeholders to verify standards. For buyers who prioritize conscious consumption this means the gem you acquire comes with a clear provenance story, full disclosure of heat treatment, and a commitment that your purchase contributes to a supply chain that supports people and place.

For a buyer assembling a thoughtful collection this tanzanite offers both intrinsic beauty and responsible provenance, a rare combination that appeals to those who care about craft and conscience. Its size and cut make it versatile for fine jewelry settings such as a solitaire pendant where color is showcased, or a halo ring designed to emphasize the vivid blue violet tone while still preserving the stone as the focal point. Practical considerations include gentle daily care, avoiding ultrasonic cleaning and harsh chemicals, and removing the piece for activities that risk hard impact, as tanzanite has a Mohs hardness around six to seven and benefits from mindful wear. We at The Natural Gemstone Company are happy to provide additional detailed images, viewing videos, and independent gemological reports upon request to support confident decision making. If you would like a bespoke mounting recommendation or information on sizing and setting to complement this gem, we can coordinate with experienced jewelers to ensure the final piece reflects both the gem s natural character and your values as a conscious collector.
