13.46 Ct. Cabochon Rutilated Quartz from Ceylon (Sri Lanka)

I am pleased to introduce a remarkable specimen from The Natural Gemstone Company, a transparent bluish grey rutilated quartz of exceptional charm and character. This stone weighs 13.46 carat, and presents a classic oval shape that reads as both elegant and organic. The cabochon cut allows the internal scenery of fine rutile needles to take center stage, creating a living pattern that shifts with every slight movement. Originating in Ceylon Sri Lanka, this gem brings a provenance of quality and tradition, and its light color intensity ensures that the bluish grey tone remains subtle and versatile. Whether you are a collector seeking a distinctive addition or a jeweler drafting a bespoke piece, this rutilated quartz offers a compelling balance of visual intrigue and wearable size.

For those who appreciate exacting details, the dimensions of this gem are 18.31 x 13.62 x 7.50 mm, a comfortable size for a statement ring or an eye catching pendant. The clarity grade is very slightly included when evaluated at eye level, which in rutilated quartz is a cherished attribute because it enhances the contrast and definition of the needle like inclusions without obscuring the overall transparency. The stone has an excellent polish, providing a smooth, reflective surface that accentuates its internal needles and the bluish grey hue. There has been no enhancement applied to this gem, and we stand by that description. The combination of transparency, cabochon cutting and very slight inclusions results in a gem that appears both ethereal and dramatic, ideal for designs that celebrate natural patterns rather than conceal them.

Rutilated quartz is prized for the unique, hairlike rutile inclusions that form intricate patterns inside the crystal, and this stone is an outstanding example. The needles appear as delicate, almost metallic streaks that intersect and disperse light in ways faceting does not permit, giving the gem a three dimensional tapestry. The bluish grey base color provides a cool backdrop, allowing the rutile to read as silvery or slightly darker, depending on the viewing angle and lighting. Designers will find this gem particularly adaptable, as it complements white metals such as platinum and white gold for a modern look, while yellow gold lends a warm contrast that highlights the needles. The oval cabochon shape suits a variety of settings, including bezel settings that protect the edges, low profile prong mounts for rings, and simple solitaire pendants that let the interior pattern remain unencumbered. For those creating heirloom pieces, the stone is large enough to serve as a focal point in a pendant or cocktail ring, and its polished domed surface photographs beautifully, showing depth and movement in studio lighting as well as natural light.

In terms of care and wearability, this rutilated quartz is robust enough for regular wear with thoughtful handling. Quartz has a Mohs hardness of seven, which offers reliable resistance to everyday scratches, but as with all gemstones, avoid abrupt temperature changes and exposure to harsh chemicals which can affect the surface over time. We recommend cleaning with warm soapy water and a soft brush, followed by a gentle dry with a soft cloth. Ultrasonic and steam cleaners are generally not recommended for gemstones with prominent inclusions unless tested and approved by a professional, because internal features can sometimes respond unpredictably to such treatments. Store the gem separately from harder stones to prevent surface marks, and consider protective bezel settings for rings that will see daily use. The Natural Gemstone Company guarantees the stone is natural and untreated, and we can provide documentation of origin and condition upon request to assist with appraisal or insurance.

This 13.46 carat oval bluish grey rutilated quartz from Ceylon Sri Lanka represents a rare opportunity to own a stone that is both visually arresting and versatile in design.
