Our large genuine red fossilized coral .925 sterling silver handmade earrings pair substantial oval cabochons with hand-formed Bali-style bezels. Each pair weighs between 8.9g and 18.5g depending on the model, with drop lengths around two inches. Because the stones are natural, no two pairs match exactly in pattern or saturation.
What fossilized red coral actually is
Fossilized coral is not a gemstone in the traditional mineral sense. It started as a colony of marine coral polyps, and over millions of years silica gradually replaced the original calcium carbonate skeleton. The result is agatized coral, a form of chalcedony that preserves the coral’s chambered structure.
That replacement process is why this material reads on the Mohs hardness scale at about 6.5 to 7, far harder than fresh coral at 3 to 4. The red coloration comes from iron oxide inclusions picked up during fossilization. Major commercial deposits are mined in Indonesia, the Philippines, and Florida’s Tampa Bay region.
Because the material is fossilized rather than harvested live, it sidesteps the conservation concerns tied to modern reef coral. Buyers who want the red color without the reef impact often choose this stone for that reason.
How these earrings are made
Each cabochon is cut and polished by hand, then set in a closed-back .925 sterling silver bezel. The bezel wall is pressed against the stone with a burnisher, holding the cabochon without prongs and protecting the edges from chipping. Silver content is stamped 925, meaning 92.5% pure silver alloyed with 7.5% copper for structural strength.
The Bali-style models use granulation and twisted wire detailing around the bezel, soldered before the stone is set. Other versions in our catalog feature pierced silverwork with hearts, birds, and floral motifs surrounding the central oval. Ear wires are solid sterling, not plated, so they’re appropriate for wearers sensitive to nickel.
Every pair listed is a single-piece inventory item. When you see one you like in our sterling silver jewelry catalog, that specific pair ships to you — we don’t restock identical duplicates because the stones differ.
Sizing, weight, and what to expect on the ear
Our large red fossilized coral earrings typically measure 45 to 55 mm from the top of the hook to the bottom of the bezel. Stone size on the oval cabochons runs roughly 18×25 mm to 22×30 mm. Total pair weight ranges from 8.9g for the lighter Bali ovals up to 18.5g for the heavier figural designs.
At those weights, the earrings hang with noticeable presence but stay wearable for a full day. If you’re new to larger drops, the 8.9g pair is the easier starting point. The 18.5g pair sits closer to statement-piece territory and pairs well with pulled-back hair or higher necklines.
Color across the stock runs from brick red to deeper oxblood, sometimes with visible fossil coral patterning — small circular or radial structures left from the original polyps. We photograph each pair under natural daylight so the listing image reflects the actual color you’ll receive.
Care and verification
Clean the silver with a polishing cloth, not liquid dips, which can pit the porous edges of the coral. Avoid ultrasonic cleaners and steam. Store the pair in a tarnish-resistant pouch away from rubber and wool, both of which accelerate silver oxidation.
To verify the stone is fossilized coral rather than dyed bamboo coral or reconstituted material, look for the fossil structure under 10x magnification. Real agatized coral shows the chambered polyp pattern beneath the polish. The 925 stamp on the ear wire and bezel back confirms sterling silver content under US FTC guidelines.
