17.28 Ct. Yellow Sapphire Crystal from Ceylon (Sri Lanka)

When you are searching for a gemstone that answers both the heart and the eye, this unique yellow sapphire from The Natural Sapphire Company is the kind of find that ends the search, not continues it. Many clients come to me looking for a stone that reads as both rare and wearable, something bold enough to be the centerpiece of a bespoke engagement ring, and refined enough to satisfy a serious collector. This semi transparent yellow sapphire, weighing 17.28 carat, offers exactly that balance. Its various shape and rough crystal cut give it an organic, one of a kind silhouette, with dimensions of 24.73 by 11.75 by 8.34 millimeters that make it substantial on the finger while still offering a comfortable profile for a pendant or a signature cocktail ring. The medium color intensity means the yellow is lively without being garish, and the excellent polish allows each natural facet and surface plane to catch light in a way that feels both natural and luminous.

For clients who prioritize natural, untreated beauty, this sapphire is especially compelling, because it has no enhancement. That fact alone places it in a different category from many commercial stones, offering a true collector grade specimen with provenance from Ceylon Sri Lanka. The clarity grade is very very slightly included, evaluated at eye level, which translates to a stone that reads clean to most observers, while retaining the internal character that tells the story of its geological journey. The rough crystal cut is a design advantage if you want a stone with personality. It is not a mass produced, perfectly faceted copy, it is instead a gem that shows growth lines, terminations, and natural planes, which are enhanced rather than obscured by the excellent polish. For someone seeking an engagement ring that feels singular, or a collector wanting a display piece that sparks conversation, these qualities are essential. The substantial 17.28 carat weight gives presence, and the semi transparent nature provides a warm glow when set near light, allowing the yellow to deepen and the stone to breathe with movement.

When thinking about how this sapphire will perform in everyday wear and in design, the material benefits of sapphire are reassuring. Sapphire is a member of the corundum family, renowned for its durability and resistance to scratching, which makes it an excellent choice for a piece intended for regular wear such as an engagement ring or an heirloom pendant. Because this stone is untreated, you are getting the natural color and structure as it formed in the earth, which for many clients is a moral and aesthetic preference. The various shape and rough crystal cut invite creative settings, and I can suggest several directions that showcase the stone while protecting it. A bezel setting will echo the stone s organic outline and offer maximum protection at the edges, while a softly scalloped prong setting will allow more light to enter and emphasise the stone s natural facets. For collectors who plan to keep the stone loose, a custom display mount that cradles the terminations will allow its crystal geometry to be appreciated from multiple angles. In all settings, the excellent polish gives surface brilliance that reads as refinement, while the medium color intensity ensures the stone remains wearable and versatile with many metal choices, from warm 18 karat yellow gold that will harmonize with the yellow, to 18 karat white gold or platinum for a modern, contrasting presentation.

At The Natural Sapphire Company we pride ourselves on guiding clients from selection through to finished design, and this sapphire is a prime example of the kind of natural gem that benefits from our bespoke service. We can provide high resolution images, additional viewing angles, and if you desire, a video showing the stone in different lighting conditions so you can see how its semi transparent body and medium color intensity perform in daylight and in warm indoor light. If certification or a full gemological report is important to you, we can assist with that process and recommend trusted laboratories. For the client who is seeking investment quality, the no enhancement origin of Ceylon Sri Lanka is a significant selling point, and the 17.28 carat weight places the stone in a size category that is rarely found untreated and unheated. If your priority is creating a memorable engagement ring, this gem will give you a narrative to tell, a piece that is unmistakably natural, and a silhouette that will not be replicated easily. If your priority is collecting, you will appreciate the crystal form, the natural growth features, and the provenance, all of which contribute to both emotional and market value. When you are ready, I am available to discuss setting ideas, expected timelines for bespoke work, and any questions about care and insurance that will help you feel confident that this sapphire is the conclusion to your search.
