13.40 Ct. Purple Amethyst from Ceylon (Sri Lanka)

From the heart of Ceylon Sri Lanka where ancient trade routes met tropical soils, this purple amethyst began its story as a slow crystallization deep within volcanic rock. Over eons iron atoms and natural irradiation coaxed a regal purple to emerge, a color prized by kings and artisans for centuries. Our miners work in small, respectful operations where knowledge is passed down through generations, and each piece is chosen for its character and clarity. The rough that became this gem showed a promise, a deep vivid tone that sung even before the first facet was mapped. At The Natural Gemstone Company we trace that journey from the earth to your hands, honoring the origin with careful documentation and with craftsmen who understand how to reveal a stone without losing its story. This amethyst carries with it the warmth of Ceylon sunlight, the patience of geological time, and the quiet dignity of stones that have been part of human adornment for millennia.

The transformation from rough to the finished 13.40 carat cushion shaped amethyst was an exercise in restraint and vision. The cutter chose a mixed brilliant cut to balance flash and depth, to open the vivid purple while maintaining the gem weight that gives presence in a finished piece. The finished dimensions 18.03 by 11.97 by 9.95 mm were achieved by preserving generous pavilion depth and a well proportioned crown, resulting in an interplay of light that produces scintillation and color constancy. The gem is transparent, with a clarity grade described as very very slightly included when evaluated at eye level, meaning the inclusions do not detract from the gem s beauty to the naked eye. An excellent polish completes the work, allowing table to facets to sing with every movement, and there has been no enhancement applied to alter its natural hue. The result is a stone that reads as utterly authentic, a vivid purple amethyst that retains the geological signature of its Sri Lankan origin while offering every optical attribute a jeweler looks for.

Because of its generous weight and the classic cushion silhouette, this amethyst is an ideal choice for custom jewelry. The dimensions and cushion outline translate beautifully into a wide range of designs, from a bold solitaire ring that sits as a modern heirloom to a low profile bezel pendant that moves gracefully on a chain. This size is also perfect for halo settings where diamonds or other accent stones frame the cushion to amplify brilliance, or for three stone compositions where matching side pieces can be chosen to harmonize with the vivid center. The mixed brilliant cut gives a lively face up appearance, making the stone read larger than the carat weight alone might suggest, and the eye clean clarity means settings can be designed with open galleries to increase sparkle without the need to hide imperfections. For designers seeking contrast and softness, pairing this amethyst with White Opal as accent stones creates a poetic counterpoint, the opal s milky play contrasting with the amethyst s saturated purple, producing depth and movement across the piece. At The Natural Gemstone Company we are happy to advise on setting choices that preserve weight while showcasing the cushion form, and to provide CAD sketches or sample mountings to ensure the final piece matches your vision.

Imagine this amethyst set and worn, the way its facets catch morning light and deepen in evening, a color that complements a wide palette of metals and gemstones. In a warm yellow gold it takes on a vintage romance, in a cool white metal it reads as contemporary and graphic, and with rose gold it finds a soft feminine conversation. The stone s origin in Ceylon adds a narrative for the wearer, a conversation starter about place and provenance, and the fact that it is untreated gives confidence to collectors who value natural integrity. If you are commissioning a custom engagement ring, a statement ring, or a unique pendant, this cushion amethyst offers a rare combination of presence and versatility.
