1.35 Ct. Purple Cabochon Star Spinel from Ceylon (Sri Lanka)

This purple star spinel from Ceylon offered by The Natural Gemstone Company is a finely proportioned 1.35 carat round cabochon, measuring 6.61 by 6.25 by 3.59 millimeters, with an intense, saturated purple hue and an excellent polish. The gem is graded as very very slightly included when evaluated at eye level, which means it presents with exceptional clarity to the unaided eye, while still retaining the natural internal features that contribute to its optical character. There has been no enhancement to this stone, a fact that enhances its appeal to discerning collectors and connoisseurs who prioritize natural material and traceable origin. The cabochon cutting style is deliberately chosen to maximize the asterism, and under a single overhead light this spinel displays a distinct six rayed star that sears across the dome, the rays appearing crisp and well centered against the deep purple body color. The star is a natural asterism produced by densely aligned internal inclusions that reflect and scatter light along specific directions, an effect that moves subtly with changes in the light source and appears most vivid when the gem is viewed face on, confirming both the quality of the crystal and the skill of the lapidary work.

For customization this 1.35 carat round cabochon is exceptionally versatile and lends itself to a wide range of fine jewelry settings, from a classic bezel or frame that protects the dome to a selective open back mount that intensifies the color, depending on the design intent. It is ideally suited to single stone settings for rings and pendants where the star can be oriented to face upward toward typical light sources, and it also adapts beautifully to halo or split shank designs where smaller accent stones provide contrast and scale. For a modern aesthetic the gem works well in low profile bezel rings and in cufflink or signet style pieces for men, while paired mounts make elegant earrings and matched sets. Metal choice will influence the perceived depth of color, with warm yellow gold enriching the purple tone and platinum or white gold offering a cooler contemporary contrast. Because the dome is the defining feature, we recommend the setting be designed to protect the table and maintain easy viewing of the asterism, and that installation be handled by an experienced jeweler familiar with orienting star stones. Sourced, unenhanced, and expertly finished, this star spinel is a rare natural specimen that combines gemological integrity with strong design potential, an ideal selection for the educated buyer seeking a distinctive, wearable treasure.
