[QUOTE="Ce BCA, post: 4004130, member: 18716"]In case it's interesting to others reading. Agate is technically chalcedony with quartz and does come in many colours, including red. Traditionally the name carnelian was reserved for the red/orange translucent chalcedony (like a red/orange version of chrysoprase), so in effect the high quality pure end of red agate, like this: [ATTACH=full]325829[/ATTACH] If it's banded, more cloudy/opaque obviously zoned we would call it agate in the UK. The naming conventions are just differentiating the quality and colour of the mineral, the base mineral is the same but with a slightly different blend. So chalcedony with iron is red/orange and called carnelian (or sard if it's brown), chalcedony with nickel is green and called chrysoprase - tiny amounts of impurities alter the colours and the naming. So the terms are just names for orange chalcedony, green chalcedony etc. TLDR: It's pretty much all quartz and because we didn't know that in ancient times many different names are used for what are in effect the same thing but in different colours/clarities. Well done if you're still awake haha.[/QUOTE]
