1.60 Ct. Multi Color Crystal Opal (Jelly Opal) from Ethiopia

This listing describes a single, semi-transparent Crystal Opal Jelly Opal, weighing 1.60 carat, presented in a classic oval shape with exact dimensions of 10.16 x 7.97 x 4.77 mm. The gemstone has been faceted in a mixed brilliant cut, providing a structured play of light across the pavilion and crown, and it exhibits an excellent polish. Color intensity is assessed as medium intense, with a multi color display that ranges across green and orange flashes visible in the supplied images. Clarity is graded as very slightly included, evaluated at eye level, which is consistent with the internal features commonly encountered in high quality jelly opals. The piece has been heat treated, a disclosed enhancement undertaken to improve visual attributes, and the overall presentation is suitable for precision settings that benefit from a faceted profile.

The origin of this opal is Ethiopia, and that provenance contributes materially to its character and market desirability. Ethiopian crystal opals are noted for their transparent to semi-transparent body tone and vivid, often broad flashes of color that respond well to cutting and polishing techniques. Mines in Ethiopia have supplied notable quantities of jelly and crystal opal since the early 21st century, and stones from this region are frequently prized for their clarity, lively color play, and adaptability to faceting, attributes that are evident in this specimen. The Ethiopian origin also implies the possibility of hydrophane behavior in some individual stones, a trait that makes handling and testing important for accurate assessment, and that can be an attractive quality for collectors and designers seeking an interactive gem.

The Natural Gemstone Company provides this description to document key technical information and to assist in selection and care. Heat treatment has been applied and is disclosed, and buyers should note standard precautions for opal care, including avoiding sudden temperature extremes and prolonged exposure to harsh chemicals, and considering sealing or protective mounting in designs exposed to impact or abrasion. The combination of a precise mixed brilliant faceting, a medium intense multi color play, very slightly included clarity at eye level, and Ethiopian provenance defines the specimen as a distinct Crystal Opal Jelly Opal, suitable for use in fine jewelry where a semi-transparent, color reactive centerpiece is desired.
