3.76 Ct. Star Ruby from Vietnam

One exquisite oval star ruby of 3.76 carats is presented by The Natural Ruby Company, a remarkable example of natural beauty and classic gemstone appeal. This stone measures 11.18 by 8.84 by 3.68 millimeters, a comfortable size for a statement ring or an elegant pendant. The gem is cut en cabochon to reveal and enhance its star asterism, producing a crisp moving star when viewed under a single light source, and the body color is a refined pinkish red that reads as vivid and lively in daylight and incandescent light. The piece is opaque as is common for high quality star rubies, and has been evaluated as slightly included at eye level, which contributes to its strong star effect without detracting from its overall visual impact. The polish is excellent, providing a smooth, glossy dome that allows the star to glide across the surface with movement, and the stone is entirely natural with no enhancement, sourced from Vietnam, a locality known for producing attractive star rubies with character and depth.

Optical performance is one of the strongest attributes of this gem, the combination of rich color and a pronounced star creates an immediate eye catching presence, even at modest carat weight. Because the stone is cabochon cut, the interplay of light and the internal silk inclusions produces asterism that appears centered and readable, providing a steady six ray type star under direct illumination that shifts gently with motion. The clarity grade of slightly included at eye level is typical for asteriated rubies, and in this specimen those inclusions act as the medium for the star rather than as a detractor, giving the gem its unique optical identity. The intense color intensity enhances the contrast of the star, allowing the white ray to stand out against the warm pinkish red field, and the excellent surface polish deepens the hue and contributes to a lively, reflective sheen. Because the stone is untreated, collectors and connoisseurs who prioritize natural, unenhanced material will appreciate the rarity and integrity of this Vietnamese star ruby, as it requires both the right natural internal structure and skilled cutting to display such a pronounced star without heating or other modification.

From a design and setting perspective this 3.76 carat oval cabochon is versatile and well suited to several applications, and The Natural Ruby Company can assist with custom settings to showcase its star to best advantage. For daily wear and to protect the dome, a low bezel or partial bezel is often recommended, keeping the stone secure while allowing the star to be illuminated from above. For a ring that emphasizes the gemstone as a focal point, a classic solitaire with a smooth bezel or a refined halo of diamonds set slightly below the dome can create a stunning contrast and elevate the perceived intensity of the pinkish red body color. For a pendant, a simple open top mounting that permits light to play across the surface will keep the star vivid and dynamic. Metals such as warm yellow gold or rose gold enhance the red tones, while white gold or platinum provide a neutral backdrop that allows the color and star to be judged purely on their own merits. Because this ruby is slightly included at eye level, secure prong work or a bezel is preferable to prevent impact on exposed edges, and The Natural Ruby Company can recommend experienced jewelers who understand how to set cabochons to preserve their optical properties.

Care and long term enjoyment of this natural star ruby are straightforward, and simple handling will preserve its luster and star performance for generations. Avoid harsh chemical cleansers and prolonged exposure to extreme heat or steam, because although this stone is not heat treated, aggressive cleaning is unnecessary and could compromise a mounting. Routine cleaning with warm soapy water and a soft brush is effective, followed by gentle drying with a soft cloth. Ultrasonic cleaners are generally not recommended for heavily included cabochons, because the vibrations can sometimes affect the stability of certain internal features or the setting, therefore gentle manual cleaning is the preferred approach.
