Three Stone Greyish Blue Sapphire Ring 1.60 Ct., 14K White Gold

This ring centers a 1.60 carat oval greyish blue sapphire, cut as a cabochon with dimensions of 6.50 by 6.40 by 3.41 millimetres, originating from Ceylon, Sri Lanka. The cabochon cut is a deliberate choice to emphasize the stone’s bodycolour, silky luster, and any optical phenomena inherent to the crystal, rather than the scintillation produced by faceting. The gently domed surface and precise oval symmetry of this sapphire create a continuous plane for light to interact with the stone’s outer surface and its internal structure. With a medium colour saturation and a clarity grade assessed as very very slightly included at eye level, the cutter has oriented and shaped the cabochon to present an even wash of colour and to maximise the apparent depth and uniformity of tone. The 3.41 millimetre dome height is balanced to allow incident light to be captured and reflected back to the viewer in a controlled, soft manner, producing a strong, mirror-like surface sheen while preserving the stone’s internal character. Excellent polish further enhances this effect, ensuring that reflected light is uninterrupted by surface abrasions and that the cabochon displays a clean, continuous highlight across its dome.

The design incorporates two tapered baguette natural diamonds, together weighing approximately 0.08 carats, graded colour F and clarity VS1 to VS2. Tapered baguettes employ step facets that reflect and refract light in linear planes, creating measured flashes and a crisp edge contrast to the sapphire’s rounded form. Placed on either side of the cabochon, these stones serve both to frame the central sapphire and to introduce angular reflections that catch the eye, directing attention toward the centre. The VS clarity and F colour ensure that the baguettes contribute brightness without colour bias, while their cut and proportion have been selected to complement the cabochon’s size and profile. The setting allows light to reach the diamond facets from multiple angles, where the step-cut geometry returns controlled brightness to the eye and establishes a visual bridge between the cool white luminance of the diamonds and the greyish blue depth of the sapphire.

The entire composition is executed in 18 karat white gold, a metal choice that supports the optical goals of the piece by offering a reflective, neutral backdrop. The polished white gold prongs and open gallery are configured to maximize light transmission to and from the gemstones, permitting reflections from the metal to reinforce the perceived brightness of both the cabochon and the baguettes. The prong and basket architecture lifts the cabochon sufficiently to allow light to graze the dome and interact with internal features, while the tapered diamond settings are oriented to channel reflected light toward the centre. Attention to proportion, stone orientation, and finishing is evident in the way surface reflections on the cabochon appear clean and continuous, and in the manner the baguettes return linear highlights that frame and enhance the central sapphire. Crafted and presented by The Natural Sapphire Company, this ring demonstrates how a cabochon cut, when executed with precision and combined with complementary step-cut diamonds and a reflective white gold setting, can maximise perceived brilliance and create a composed, luminous presentation that emphasises luster, colour integrity, and optical harmony.
