AI-assisted summary
Description from the seller
OPAQUE BLUE OPAL – 925 SILVER PENDANT – ARTICULATED BUCHE BAIL – TRADITIONAL JEWELRY
1. Piece overview
The blue of the ocean transformed into a jewel.
Spectacular opaque blue opal pendant in an intense sky-blue hue, with delicate whitish formations reminiscent of clouds over a tropical sea.
Its elegant oval cabochon cut, 925 silver setting, and traditional articulated BUCHE bail create a jewel with great character.
A piece that combines mineral beauty, elegance, and craftsmanship details rarely found in today’s commercial jewelry.
2. The mineral: blue opal
Blue opal belongs to the common opal family, a group of mineral materials known for their attractive colors and hydrated silica structure.
Unlike precious opal, common opal does not need to display play-of-color to be appreciated in jewelry.
Its beauty lies in its color intensity, texture, and the natural patterns of each specimen.
3. Gemological characteristics
Mineral: common blue opal, commercial identification based on visual examination.
Chemical composition: SiO₂·nH₂O.
Family: hydrated silica.
Hardness: approximately 5.5–6.5 Mohs.
Color: intense sky blue with whitish areas.
Transparency: completely opaque.
Cut: oval cabochon.
Finish: glossy polish.
Setting: 925 sterling silver.
Bail: traditional articulated BUCHE.
4. A cut that enhances the color
The oval cabochon cut provides a broad, continuous surface that showcases the intensity of the blue and its subtle whitish variations.
Unlike a faceted gemstone, this type of cut puts the focus on the color and the beauty of the material itself.
Its convex surface adds volume and a particularly elegant presence.
5. 925 sterling silver setting
The mineral is framed by an oval 925 silver setting, an alloy composed of 92.5% fine silver.
The contrast between the intense blue and the silvery sheen creates a highly appealing combination.
The setting follows the outline of the cabochon and allows the stone to take center stage.
6. Traditional BUCHE bail: distinction and functionality
One of the most valuable features of this jewel is its articulated BUCHE bail, characteristic of traditional jewelry.
It differs from conventional rings through its broad structure, volume, and more labor-intensive craftsmanship.
Its main advantages are:
It accommodates thicker chains thanks to its wide opening.
It reduces the pendant’s tendency to turn, providing greater stability.
It helps the jewel stay in place and face forward, displaying its main side.
It gives the overall piece greater presence and character.
This system is uncommon in today’s commercial manufacturing, where simpler, more economical bails predominate.
The BUCHE is not merely an accessory: it is a jewelry feature that adds functionality, personality, and distinction.
7. Color and presence
The pendant features an intense sky blue, accompanied by soft, cloud-like white formations.
Its coloration is opaque, with no appreciable light passing through the stone.
The glossy polish enhances the surface and allows you to appreciate its color contrasts.
A particularly appealing combination for those who appreciate richly colored jewelry.
8. Mineralogical origin
Common blue opals are found in different regions around the world.
Peru is especially known for its ornamental blue opals, although materials from this family are also found in other countries.
The specific geographic origin of this specimen is undocumented, so it is not attributed to any particular deposit.
9. History and tradition of opal
Opal has attracted interest since antiquity for its variety of colors and appearances.
Although precious opals are known for their multicolored flashes, common opals have been used for generations to make cabochons, beads, and ornamental objects.
Blue specimens stand out for their distinctive aesthetic, especially appreciated in contemporary jewelry.
10. Condition
Pendant with polished cabochon and complete setting, as shown in the photographs.
The mineral has a uniform-looking surface, with color variations characteristic of its ornamental appearance.
The images show the design of the setting and articulated bail.
11. Dimensions and weight
Shape: oval.
Cut: cabochon.
Thickness: approximately 0.5 cm.
Height: to be added.
Width: to be added.
Total weight: to be added.
Setting: 925 silver.

12. Authenticity and selection criteria
The piece is commercially presented as opaque common blue opal, based on visual identification and our own gemological assessment.
No independent gemological certificate or documentation regarding possible treatments to the material is provided.
The setting is identified as 925 sterling silver based on the information available.
In selecting our mineral jewelry, we pay particular attention to material composition, setting quality, and the features that distinguish authentic pieces from imitations.
13. Value of the piece
This pendant brings together four particularly appealing features:
Intense sky-blue color with strong visual impact.
Opaque oval cabochon with delicate whitish formations.
925 sterling silver setting that adds elegance and material value.
Articulated BUCHE bail, functional and uncommon in contemporary commercial jewelry.
A jewel selected for its aesthetic, character, and distinction from conventional designs.
14. Gemological curiosities
Opal is a form of hydrated silica whose internal structure differs from that of crystalline quartz.
Its water content can vary depending on the specimen and its geological formation.
Not all opals are transparent or display multicolored flashes.
Opaque common opals are a distinct ornamental category, appreciated for their colors and patterns.
In blue materials, the combination of sky-blue and white hues can create a visual effect reminiscent of the sky or sea.
15. Care and maintenance
Opal requires proper care to preserve its appearance.
We recommend:
Avoid impacts and scratches.
Do not expose it to extreme temperatures.
Avoid chemicals, perfumes, and detergents.
Do not use ultrasonic cleaning equipment.
Gently clean with a slightly damp cloth.
Store separately from other jewelry to protect the polish.
16. Collector’s perspective
Not all jewelry stands out for its rarity. Some pieces are distinguished by the harmony between the mineral, the setting, and the quality of their craftsmanship.
This pendant combines the intensity of blue opal, the noble quality of 925 silver, and a traditional BUCHE bail whose functionality reflects a more elaborate approach to jewelry making.
A choice for those seeking beauty, character, and details not commonly found in commercial manufacturing.
