Golden Jasper is an opaque, microcrystalline variety of quartz characterized by rich mustard-yellow and golden-brown hues often featuring intricate banding or mottling. It is a highly durable material popular in lapidary for cabochons and decorative carvings due to its ability to take a high polish. Collectors typically find it in sedimentary deposits where silica-rich fluids have replaced or filled voids in host rock.
Is this golden jasper?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch golden jasper with a known reference. Golden Jasper sits at Mohs 6.5-7, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Golden Jasper leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Golden Jasper typically shows a waxy luster.
- 4Match the color rangeCompare against the expected color range: yellow, gold, brown, mustard.
- 5Look at form & habitCrystal system: trigonal. Typical habit: massive.

Field-hunting tip
Look in sedimentary country, the host setting where golden jasper typically forms. If you start seeing quartz, chalcedony, hematite in float, you are in the right ground. Field specimens usually show a massive habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Tennessee. Start trip planning there.
