These brown and gold coloured ammonites come in a variety of sizes, from very small pieces which are suitable for jewellery to very large pieces, some as big as 60 cm (2 feet) across. The “golden colors” are actually barite and calcite mineral replacements on the original fossil specimen, caused over millions of years of the fossil process.

On occasion this fossil specimen has been cut in half to show the inner coils and chambers. These ammonites show the perfection of the ammonite, they are very well preserved, almost every chamber is intact, there are distinctive lines separating the individual chambers. When polished on the outside, often suture and growth lines cover the ammonite. This of course makes the ammonite extremely beautiful, which makes it more sought after, as well as more valuable and rare.

The main types of ammonites found in these golden colours are the cleoniceras, desmoceras, nautilus, beudanticeras, argonticeras, aieoceras, colignoceras, dactylioceras, alligaticeras, and perisphinctes to name a few. A lot of cleaning and polishing work goes into every one of these unique pieces. The ammonites must be polished very carefully by expert polishers to avoid breakage. The age of the chambered ammonites vary from 65 million to 135 million years old.
