17.36 Ct. Star Ruby from Mozambique

When you are searching for a ruby that stops the search in its tracks, this beautiful natural star ruby answers that need. Many customers come to The Natural Ruby Company looking for a stone that combines size, presence, and natural character, whether the goal is a one of a kind engagement ring, an heirloom piece that will be admired for generations, or a rare specimen to add to a serious collection. This oval shape pinkish red star ruby weighs a commanding 17.36 carats, and its substantial dimensions of 14.81 by 12.33 by 9.57 mm give it an on hand presence that few stones can match. The cabochon cut is the time honored form for asterism, designed to reveal a crisp star that floats across the surface, and for buyers who want the drama of a moving star under light, this gem fulfills that desire in a direct and immediate way.

From a gemological and aesthetic standpoint this ruby is exactly what discerning clients request, a transparent material that still displays a distinct and appealing asterism. The clarity grade is included when evaluated at eye level, and that internal character is actually part of what creates the sharp star effect you see, a six ray star that sits squarely in the dome when viewed from the top. The color is best described as pinkish red with an intense color intensity, a hue that reads lively in daylight and rich under warm light, providing versatility for different settings and wear conditions. The polish is excellent, which means the surface is smooth and reflective, allowing the star to glide and focus beautifully when the gem is viewed under directional illumination. Importantly this stone has no enhancement, it is untreated, and it is from Mozambique, a source that continues to produce some of the most sought after rubies on the market today. For collectors and investors who prioritize natural state and documented origin, these factors are essential.

If you are picturing this ruby set into jewelry, imagine a high dome cabochon mounted to show the star in full effect, a design where the top view is uninterrupted and the light can bring the asterism alive. For an engagement ring, the combination of size and natural star creates drama and symbolism that ordinary faceted stones cannot duplicate, a literal shining star to represent a singular promise. For a collector, this piece offers both visual pleasure and the tangible qualities that drive long term value, transparency, strong star effect, no enhancement, and a reputable origin. The oval shape makes it flexible for a number of design directions, from a classic solitaire bezel that keeps the dome protected, to a more contemporary open gallery that allows light to travel through the stone and accentuate color and depth. Because the gem is generous in size, it can function as a center of gravity in larger bespoke work, or it can be the special signature gem in a museum style display.
