4.40 Ct. Cabochon Tourmaline

Thank you for considering this exceptional gemstone from The Natural Gemstone Company, one beautiful translucent 4.40 carat oval shape bi color tourmaline, a specimen that combines visual appeal with a sense of natural story. The gem measures 10.33 x 8.70 x 6.16 mm, and it has been fashioned into a graceful cabochon cut, a choice that accentuates the stone and allows its internal character to become part of the design. The clarity grade is included, evaluated at eye level, which means that the stone carries natural inclusions that are visible to the naked eye, and these inclusions serve as proof of its natural origin and add a unique fingerprint to the piece. The color intensity is described as intense, and that liveliness of hue is complemented by an excellent polish that delivers a smooth, reflective surface rich in sheen. The gem has undergone heat treatment to enhance its color stability and saturation, and the origin of this tourmaline is unknown, which gives it an intriguing provenance and makes it a versatile choice for a variety of custom pieces.

As a cabochon, this bi color tourmaline shows color in broad, supple planes rather than faceted flashes, which provides a more intimate and soft interplay of tones that will respond beautifully to changes in light and viewing angle. The bi color nature of the stone means that you will observe two distinct color zones, and in this particular specimen the transition between hues is pleasing and organic, offering designers and collectors the opportunity to showcase contrast and balance in a single gem. The excellent polish enhances the tactile feel of the stone, ensuring it is pleasing to touch and comfortable to wear, while the translucent body allows internal features to glow when backlit or placed in bright daylight. Because the clarity is included at eye level, the stone has character lines and natural growth patterns that tell a story of formation deep within the earth, and many customers find that these natural marks make the gem more interesting and emotionally engaging than a completely flawless example.

From a design and wearability perspective, a 4.40 carat, 10.33 by 8.70 mm oval cabochon sits comfortably as the focal point for a medium to large ring, an elegant pendant, or as a single statement earring. The cabochon profile lends itself to bezel settings, which protect the girdle and provide durability for everyday wear, or to decorative prong work that highlights the color transition across the surface. Because the piece is heat treated, it benefits from enhanced color, but I recommend treating the stone with the same care you would afford any gem of value, avoiding strong sudden impacts and prolonged exposure to high heat. Cleaning with warm soapy water and a soft brush will keep the polish vivid, and professional cleaning methods should be discussed if you plan to use ultrasonic or steam cleaners, as those methods are best confirmed by a trusted jeweler for each specific stone. The size and weight make it ideal for a design that shows off the bi color effect, so consider settings that allow light to interact with both color zones, such as open backed bezels or halo styles that frame the stone.
