39.24 Ct. Amethyst from Ceylon (Sri Lanka)

One exceptional transparent amethyst is presented, a 39.24 carat trillion shape gem with precise dimensions of 23.90 x 23.54 x 14.92 mm, cut in a classic trillion style to emphasize symmetry and optical performance. This stone is notable for its vivid color intensity and eye clean clarity when evaluated under normal unaided viewing, attributes that contribute to a strong visual presence without the need for enhancement. The polish is graded excellent, providing sharp facet junctions and a highly reflective surface that enhances brilliance and color saturation. Origin is Ceylon Sri Lanka, a source known for well formed crystals and consistently appealing color profiles, and the gem is supplied with the assurance that no treatments or enhancements have been applied, preserving natural origin and properties.

The combination of large dimensions, significant weight, and the triangular silhouette makes this amethyst particularly well suited to central roles in bespoke jewelry, while its excellent polish and vivid tone allow for both modern and traditional interpretations. In a ring application this stone will create a commanding focal point, ideally set to show the table face up where the color and facet pattern can be fully appreciated. As a pendant the generous face up area will catch light and provide a bold centerpiece, while as a brooch or statement cuff the substantial mass and precise cut will lend presence without the need for additional stones. The eye clean clarity ensures that the visual impact is driven by color and cut rather than by visible inclusions, giving designers flexibility in how much metal and additional accent work are used to support or contrast the stone.

When planning custom settings, several approaches enhance both aesthetics and security, and these can be tailored to the intended use and wearer lifestyle. For rings and pendants that receive regular wear, protective V prongs positioned at each point of the trillion shape, or a partial bezel that shields the corners while allowing light to enter the pavilion, are recommended to minimize risk to the apex points. A halo of small diamonds or colored gemstones will amplify perceived size and color intensity, and can be used to create contrast or continuity with the chosen metal. For modern designs, a tension style or three prong solitaire can emphasize clean lines and the triangular geometry, while a cluster or three stone composition can integrate the amethyst as the central element with complementary side stones for balance. Mounting considerations include an open gallery to maximize light return when brilliance is a priority, or a closed back to concentrate color for settings where deeper tone is preferred, and metal choices such as platinum and 18 karat white, yellow, or rose gold will influence the perceived warmth and contrast of the purple hue.

The Natural Gemstone Company can assist at every stage of customization, providing detailed measurements and high resolution imagery to help designers and clients plan proportions and settings with precision. Our experience with bespoke projects supports the creation of balanced shanks and engineered settings that compensate for the stone mass and ensure long term wearability, and we can advise on prong profiles, bezel heights, and secure mounting techniques that respect the trillion form. For collectors and designers seeking documentation, we provide origin disclosure and treatment statements, and can coordinate additional gemological reports if required. This amethyst presents a rare opportunity to craft a singular piece, whether as a signature cocktail ring, a refined pendant, a striking brooch, or a custom set that pairs smaller accent stones to complement the dominant triangular profile, and our team will work to translate technical specifications into enduring jewelry that highlights the natural beauty and structural elegance of the gem.
