0.96 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This listing presents one transparent cushion shape purple amethyst, weighing 0.96 carat, with precise dimensions of 6.15 x 6.12 x 4.36 mm. The gem is fashioned with a mixed brilliant cut that combines a faceted crown and pavilion geometry to optimize light return and scintillation. Clarity has been graded as very slightly included when viewed at eye level, indicating only minor internal features that do not materially affect visual performance. Color intensity is described as light purple, and the gem exhibits an even distribution of tone across the table and crown facets. The polish is excellent, resulting in crisp facet junctions and bright facet reflections. No enhancements have been applied, and the origin of the material is Ceylon Sri Lanka. For those reviewing related material types, the opal type associated with our offerings is White Opal. The Natural Gemstone Company lists this specimen for customers seeking a naturally sourced, well cut amethyst with transparent clarity and unaltered treatment history.

From an optical perspective this amethyst offers a type of brilliance that differs from more commonly cited gemstones, and that difference is useful to understand when comparing options for jewelry. Amethyst belongs to the quartz family, with a typical refractive index range near 1.544 to 1.553 and a modest dispersion value, which means that its brilliance relies more on clean facet work and saturation of color than on fire or spectral dispersion. By contrast, diamond demonstrates much higher refractive index and dispersion, which generate pronounced fire and an intense return of white light. Sapphires and rubies have higher refractive indices and greater overall light return than quartz based gems, producing a denser visual brightness in comparable settings. The mixed brilliant cut of this cushion amethyst compensates for the inherent optical limitations of quartz by creating strong internal reflections and lively scintillation. The result is a stone that communicates clarity and lively surface sparkle, while maintaining a distinctly colored presence, rather than the prismatic fire associated with diamond. Compared to other colored stones such as citrine or topaz, this amethyst displays a subtler yet more consistent purple hue, and its light color intensity provides versatility in both warm and cool metal settings.

Practical considerations for the end user include setting recommendations, care guidance, and the manner in which this amethyst stands out in finished pieces. With a Mohs hardness near seven, amethyst is suitable for daily wear when secured in protective settings that guard the girdle and pavilion from impact. The cushion outline and mixed brilliant faceting make the gem an ideal candidate for bezel or four prong mounts, configurations that preserve the stone while allowing light to enter the crown and generate the intended brilliance. Paired or matched pieces may include White Opal, which offers a complementary visual contrast through diffuse body tone and play of color, however White Opal presents different care needs due to moisture sensitivity and lower hardness. The absence of treatments in this Sri Lankan amethyst enhances its value for collectors and designers who prioritize natural state material. The Natural Gemstone Company provides this description to support informed selection, and to document the gem specific attributes that determine its behavior in jewelry, including weight, dimensions, cut style, clarity observation, color intensity, polish condition, enhancement status, and geographic origin.
