Description

This item is a piece of jewelry, specifically a bracelet, featuring carved scarab beetle motifs made from an assortment of different gemstones. The gemstones listed are Tiger's Eye, Coral, Malachite, Lapis Lazuli, Onyx, and Carnelian. Each gemstone contributes its unique color, luster, and geological properties to the overall aesthetic and composition of the bracelet.

How to Identify

Color: Varies greatly depending on the gemstone: Tiger's Eye (golden-brown with chatoyancy), Coral (red, pink, white), Malachite (green, often banded), Lapis Lazuli (intense blue with pyrite flecks), Onyx (black, white, or banded), Carnelian (reddish-orange to brown).
Luster: Varies: Tiger's Eye (silky), Coral (dull to waxy), Malachite (silky to vitreous), Lapis Lazuli (dull to greasy), Onyx (waxy to vitreous), Carnelian (waxy to vitreous).
Texture: Smooth and polished due to carving and finishing. Individual gemstones may have characteristic internal textures (e.g., fibrous for Tiger's Eye, granular for Lapis Lazuli).
Crystal Form: The gemstones are carved into scarab shapes, so their natural crystal forms are not visible. They are typically massive or cryptocrystalline aggregates.
Cleavage: Varies by gemstone: Tiger's Eye (none), Coral (none), Malachite (perfect in one direction), Lapis Lazuli (poor to none), Onyx (none), Carnelian (none).
Geological Environment: Each gemstone originates from distinct geological settings: Tiger's Eye from metamorphic rocks, Coral from marine environments, Malachite from oxidized copper deposits, Lapis Lazuli from contact metamorphic zones, Onyx and Carnelian from silica-rich solutions in sedimentary or volcanic rocks.

Color: Multicolor (golden-brown, red, green, blue, black, orange).
Luster: Mixed (silky, waxy, dull, greasy, vitreous).
Transparency: Varies: Tiger's Eye (opaque), Coral (opaque), Malachite (opaque), Lapis Lazuli (opaque), Onyx (translucent to opaque), Carnelian (translucent).
Fracture: Varies: Tiger's Eye (splintery), Coral (uneven to conchoidal), Malachite (conchoidal to uneven), Lapis Lazuli (uneven), Onyx (conchoidal), Carnelian (conchoidal).

Quick Check

Color: Multicolor, reflecting the individual gemstones: golden-brown, red, green, blue, black, orange.
Luster: Mixed, ranging from silky to waxy to vitreous.
Streak: Varies by gemstone: Tiger's Eye (white), Coral (white), Malachite (light green), Lapis Lazuli (light blue), Onyx (white), Carnelian (white).

Physical Characteristics

Crystal Habit: Massive or cryptocrystalline aggregates for all components, carved into scarab shapes.
Cleavage Type: Varies: Malachite exhibits perfect cleavage; others generally lack distinct cleavage.
Fracture Type: Varies: Conchoidal for chalcedony varieties (Onyx, Carnelian), uneven to conchoidal for Coral and Malachite, splintery for Tiger's Eye, uneven for Lapis Lazuli.
Tenacity: Varies: Brittle for most, but Coral can be somewhat tough.
Luster Type: Mixed: Silky (Tiger's Eye, Malachite), waxy (Onyx, Carnelian, Coral), dull to greasy (Lapis Lazuli).

Formation

Each gemstone in the bracelet has a distinct formation process. Tiger's Eye forms from altered crocidolite. Coral is biogenic, formed by marine polyps. Malachite is a secondary copper mineral. Lapis Lazuli is a metamorphic rock. Onyx is a banded variety of chalcedony, forming in silica-rich solutions. Carnelian is a variety of chalcedony, typically formed in volcanic rocks.

Usage

Primarily ornamental and decorative, used in jewelry. Historically, scarabs were significant symbols in ancient Egypt, representing rebirth and protection.

Age Distribution

Geological ages vary widely for each component gemstone, ranging from millions to hundreds of millions of years.

Where to Find

Finding Tips

Authenticity Check

Examine each scarab for consistent color, banding (where applicable, e.g., Malachite, Onyx), and characteristic inclusions (e.g., pyrite in Lapis Lazuli). Be aware of dyed or synthetic imitations.

Craftsmanship

Assess the quality of the carving and polishing. Well-made scarabs will have clear details and a smooth finish.

Gemstone Properties

Familiarize yourself with the specific properties of each gemstone to better identify them within the bracelet. For example, Tiger's Eye should exhibit chatoyancy (cat's eye effect).
