9.34 Ct. Ametrine from Ceylon (Sri Lanka)

One exquisite transparent 9.34 carat oval bi color ametrine is presented by The Natural Gemstone Company, a gem of notable presence and compositional beauty. The stone measures 16.08 x 12.85 x 7.29 millimeters, and it is fashioned in an elegant oval outline with a mixed brilliant cut that combines the scintillation of brilliant facetting with the depth of step elements. The piece displays medium color intensity with a distinct division between golden citrine tones and the violet hues of amethyst, resulting in a classic ametrine bi color effect. Clarity is graded as very very slightly included when evaluated at eye level, indicating that the gem appears essentially clean to unaided vision, and the excellent polish enhances its table brightness and overall light return. This specimen has undergone heat treatment, a stable and commonly accepted enhancement for quartz family gems, and its stated origin is Ceylon Sri Lanka, giving it a clear geographic provenance that can carry both aesthetic and market significance.

From a strict gemological perspective the combination of weight, cut, clarity and polish is a primary driver of value for an educated buyer. At 9.34 carats this ametrine sits in a weight class that is attractive for both collectors and jewelry designers because it allows a substantial presence without overly compromising durability or requiring an unusually large setting. The mixed brilliant cut is chosen to balance fire and brilliance, with crown facets that disperse light and a pavilion arrangement that returns light efficiently through the table. The very very slightly included clarity grade, evaluated at eye level, confirms that there are no distracting inclusions visible to the unaided eye, which preserves both visual appeal and light performance. The excellent polish further refines facet junctions and surface smoothness, meaning minimal light scattering from surface blemishes and optimal sparkle. Heat treatment in quartz is generally aimed at improving color uniformity and reducing undesirable tones. When disclosed, as it is here, such treatment is considered an acceptable enhancement, and it does not adversely affect the stability of the gem under normal wearing conditions.

Why this particular ametrine will appeal to a discerning buyer is a matter of both aesthetics and provenance. The Ceylon Sri Lanka origin is notable because Sri Lanka has a centuries long reputation for producing high quality gems with even color distribution and superior cutting standards, and provenance can be an important value component for those who prioritize traceable supply chains. The medium color intensity of the golden and violet zones offers a versatile palette that reads richly in most lighting environments, and the clear demarcation between the two colors creates a dramatic, yet wearable, visual contrast. From a market perspective, larger, eye clean ametrines with excellent polish and a well executed mixed brilliant cut are less common than smaller or heavily included pieces, which supports premium pricing for specimens with these attributes. The gem is also practical from a jewelry manufacturing standpoint, as its proportions and table size allow it to be set as a statement cocktail ring, an elegant pendant, or a central piece flanked by accent stones without requiring excessive modifications to standard settings.

When considering how this ametrine will complement different skin tones and how best to set it, its bi color nature offers a high degree of versatility. The warm golden yellow zone flatters warm and olive skin tones by echoing underlying golden undertones, producing a harmonious and luminous effect when set in yellow gold or rose gold. The purple amethyst zone complements cooler skin tones by providing a flattering contrast to blue and pink undertones, and it reads beautifully against white gold or platinum for a cleaner, more contemporary look. For customers with neutral undertones or an interest in maximizing versatility, a two tone setting that pairs yellow gold prongs for the citrine side with white gold or platinum accents near the purple zone can emphasize the stone s natural dichotomy and create a cohesive transition between colors. In terms of design, an open prong setting will allow more light to enter and reveal the subtle shift between colors, while a bezel or partially bezel setting gives a modern profile and additional protection for the girdle. For rings, the dimensions of 16.08 by 12.85 millimeters translate to a bold yet wearable face size on average hands, ideal for a signature ring or a statement pendant that allows the bi color presentation to be viewed from multiple angles. Light direction will affect the appearance of the color zones, so designers and wearers should consider orienting the stone to showcase the desired hue more prominently in typical lighting conditions.

Care and service considerations are straightforward for quartz family gems, with the ametrine s Mohs hardness around 7 providing reasonable resistance to everyday wear, though the cut and size make secure mounting advisable for rings intended for frequent use. Ultrasonic cleaning is generally acceptable for clean, heat treated quartz, but avoid prolonged exposure to extreme heat or strong chemicals. At The Natural Gemstone Company we recommend a standard gemological report to document weight, dimensions, cut, clarity observation, color intensity, treatment disclosure and origin when provenance is an element of personal or resale value. We can also advise on metal choice, setting style and design options that will best showcase the distinct yellow and purple zoning. For the educated buyer seeking a sizeable, eye clean, and attractively faceted ametrine with verifiable origin and professional finishing, this 9.34 carat Ceylon Sri Lanka example represents a compelling blend of aesthetic drama, wearable proportions, and market respectable attributes.
