This listing presents a translucent 4.27 carat pear shape carnelian, displaying a warm orangey red hue. The gem measures 12.09 by 8.10 by 5.99 millimeters, and it is fashioned as a cabochon to emphasize color saturation and surface luster. Clarity is evaluated as eye clean at normal viewing distance, and the stone exhibits intense color intensity and an excellent polish. The material originates from Brazil and has undergone dyeing as a disclosed enhancement to achieve and stabilize its rich tone. The Natural Gemstone Company supplies this specimen with full disclosure of its characteristics and treatment history.

Carnelian is a variety of chalcedony with a long history of use across cultures, valued for its durable silica composition and its stable, vivid warm colors. In antiquity carnelian was widely employed for signet rings and carved amulets, where the opaque to translucent body and steady color responded well to detailed carving and engraving. The pear cabochon format carried practical advantages for pendants and seals, as the rounded back and smooth dome shed wear and highlighted the surface sheen. Historically artisans also used heat and infusions to enhance color, and modern dyeing follows that same practical tradition with controlled procedures to produce an even, long lasting hue that remains compatible with traditional settings.

From a gemological and practical perspective this carnelian is well suited to wearable design. Its weight of 4.27 carats and its measurements allow confident planning for a fine bezel or custom prong setting, with the cabochon top allowing a secure seat and a luminous face up presentation. Carnelian has a hardness that is typically between 6.5 and 7 on the Mohs scale, which means routine care should avoid strong abrasives and high impact, while regular cleaning with warm soapy water and a soft brush will preserve the polish. The eye clean clarity ensures that the surface and body present an even visual field, and the excellent polish enhances luster and color depth. For collectors who appreciate historical continuity, the stone invites use in rings, pendants, and seals where the warm orangey red will read consistently in both daylight and incandescent illumination.

Provenance and transparency are central to the value offered by The Natural Gemstone Company, and this carnelian is supplied with origin information and treatment disclosure. The gem comes from Brazil, a source known for producing well colored chalcedony varieties, and the disclosed dyeing is intended to produce a stable, uniform appearance consistent with historical practices of color enhancement. For reference within our broader selection we note that opal types in our inventory include White Opal, a material distinct in structure and optical behavior from chalcedony based gems. White Opal is characterized by a pale body color with potential play of color, and it occupies a different design and care paradigm compared with carnelian. Should you require additional measurements, certification recommendations, or setting options, The Natural Gemstone Company is prepared to provide further technical detail and visual documentation to assist in responsible design and acquisition.
