16.51 Ct. Cabochon Tanzanite from Tanzania

Hand selected by our gem specialists at The Natural Gemstone Company, this one beautiful translucent violet tanzanite weighs 16.51 carats, and presents in an elegant oval shape with dimensions of 17.12 x 12.63 x 8.47 mm, a size that brings presence without overpowering. The gem is cut as a cabochon cut, allowing light to play across its smooth dome and reveal a deep and inviting violet hue. Clarity is graded as included, evaluated at eye level, which gives this stone its authentic personality and character, tiny internal features that tell the story of its natural formation. Color intensity is intense, a rich violet that captures the gaze and holds it, while polish is excellent, giving the surface a lustrous finish that feels almost silky to the eye. This tanzanite has been heat treated, a common and accepted enhancement that refines the color and brings out the best of the natural material, and its origin is Tanzania, a birthplace renowned for producing the most sought after tanzanites. From the first glance you will see why collectors and designers alike are drawn to such a remarkable specimen, and because it comes from The Natural Gemstone Company you can trust the expertise behind every facet of this gem.

Imagine the moment you hold this 16.51 carat violet jewel in the palm of your hand, the way light seems to gather and sing beneath its cabochon curve, the sense of wonder that rises as the intense color moves with each tilt. This stone is not merely an accessory, it is a companion for moments that will become memories, a promise waiting to be fulfilled. Picture it set into a necklace that rests near the heart, a piece that turns ordinary days into celebrations of love, or imagine it as the center of a bespoke cocktail ring that sparks conversations and quiet compliments. The inclusions visible at eye level are a reminder that this is a natural treasure, formed over eons, and that imperfection is often the mark of true authenticity. Whether you are celebrating a milestone, marking a new chapter, or gifting something that says more than words can capture, this tanzanite carries emotion in its color, a soft but intense violet that evokes serenity, devotion, and creative spirit. Our clients often tell us that gemstones like this one seem to remember the moments in which they are worn, and that thought makes each pairing, presentation, or design feel tender and intentional.

As a gemstone specialist I want to share practical things that matter when choosing a piece like this, the technical qualities that assure lasting beauty and confidence. The cabochon cut enhances the tanzanite by emphasizing color over faceting, making it perfect for designs where a smooth, luminous surface is desired, and the 17.12 x 12.63 x 8.47 mm size offers excellent versatility for rings, pendants, or even a bold pair of earrings if matched with a companion stone. The clarity graded as included, evaluated at eye level, means that small internal features may be visible, especially under close inspection, but they do not diminish the gem they instead testify to its natural origin and add to its story. Heat treated enhancement is standard for tanzanite and is stable under normal wear, bringing out the intense violet color that catches the eye, and our excellent polish ensures the surface will continue to reflect light beautifully. When setting this gem, we recommend secure bezel or partial bezel settings that protect the cabochon dome while showcasing its color, and choosing metals that complement violet tones such as warm 18 karat yellow gold for contrast, or cool platinum for a modern elegant look. We advise gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemicals or steam, and daily wear should be mindful of sharp impacts that could chip the dome, while regular checks with your jeweler will keep your treasure safe and radiant.

There is something quietly triumphant about owning a tanzanite that carries provenance and personality, and The Natural Gemstone Company is honored to present this gem with both expertise and heart. We source responsibly and provide detailed information so you can choose with clarity and confidence, there is care in every step from selection to shipment, and an openness to help you design the perfect setting that will transform this stone into an heirloom.
