1.51 Ct. Red Cabochon Almandine Garnet from Ceylon (Sri Lanka)

This piece is a translucent round almandine garnet, precisely cut as a cabochon, weighing 1.51 carats, with exact dimensions of 6.17 by 6.22 by 3.76 millimeters. The cabochon form presents a full domed profile with a measured height of 3.76 millimeters, providing a pronounced silhouette that emphasizes body color and internal light transmission rather than faceted brilliance. Color is classified as medium intensity red, exhibiting the characteristic warm brownish undertone of classic almandine garnet from Ceylon Sri Lanka, and the polish is graded excellent, producing a sharp, glassy luster across the dome. Clarity at eye level is described as very slightly included, with minute needle and pinpoint features visible only upon close inspection under strong lighting, and no surface-reaching fractures or significant cleavage are present. This gem is natural and untreated, with enhancement status documented as none, and the combination of translucency and internal reflection yields a deep, uniform internal glow when backlit or set in an open backed mounting.

From a jeweler s perspective this cabochon offers straightforward and versatile options for custom mounting, due to its precise round outline and robust dome height. The most protective and traditionally appropriate option is a full bezel setting, which secures the girdle along a continuous metal lip, preserving the dome and reducing exposure to knocks and abrasion. For maximum visual depth consider an open back bezel or a collet with a recessed gallery, which allows transmitted light to enter the pavilion area and enhances the stone s translucency and warmth. When designing a ring, specifying a bezel seat depth closely matching the 3.76 millimeter dome height is recommended, and a seat tolerance of approximately 0.1 to 0.3 millimeters will permit adhesive or mechanical retention without rocking. For more contemporary aesthetics the cabochon can be set in a partial bezel or a low profile half bezel with four evenly spaced secure prongs that are shaped to follow the curvature of the dome, these prongs must be smoothly radiused to prevent stress concentrations on the stone. As a pendant, the stone benefits from an open back or a gallery window, which will maximize the lantern effect, and it can be mounted within a halo of small faceted accent stones to create optical contrast between the cabochon s soft glow and the sparkle of pavAŠ set diamonds or sapphires.

Design versatility extends to pairs and mixed media combinations even though this listing describes a single stone, the shape and scale are ideal for central motifs in rings, solitary pendants, cufflinks, single stud earrings where a single cabochon can read as a bold stud, and as the focal bead in a custom bezel linked bracelet. Metal selection will materially alter the perceived hue, yellow or rose gold will warm and intensify the brown red undertones, while white gold or platinum will mute warmth and emphasize the clearer red component for a cooler modern palette. Considerations for mounting include providing an inner cushion or soft polymer lining when producing cufflinks or high wear designs, specifying a hard seat and unobstructed gallery in pendants to allow light passage, and avoiding extreme mechanical stress during setting to preserve the excellent polish and prevent chipping at the girdle. When commissioning a custom piece from The Natural Gemstone Company discuss whether you prefer a flush, low profile mount for everyday wear, or a high crown and open gallery to maximize perceived depth, we can provide CAD mockups and seat dimension recommendations based on the exact 6.17 by 6.22 by 3.76 millimeter proportions. This cabochon s combination of natural Ceylon origin, unenhanced status, precise round geometry, and excellent polish makes it especially well suited to bespoke designs that balance protective setting techniques with aesthetic strategies that exploit translucency and color, and our lapidary team can advise on complementary accent stones and metal finishes to produce a finished piece that showcases the garnet s intrinsic character.
