Title: Frequently Used Lapidary Terms Post by: bobby1 on January 13, 2012, 06:54:22 pm Moss Agate - Sometimes called Mocha Stone - has wispy three dimensional filaments that look like green moss floating in a pond. Sometimes the patterns are brown, red or orange. Though it looks like real moss it isn't organic in origin. Red Moss has Iron as its coloring agent and black moss is colored by Manganese

Title: Re: Frequently Used Lapidary Terms Post by: Fullerton on February 11, 2012, 06:28:30 am Brilliant workmanship ... iparticularly impressed by the Montana Dendritic Agate in the shape of a flower

Title: Re: Frequently Used Lapidary Terms Post by: DadOhs on November 15, 2012, 08:14:58 pm just ran across this and I must express my thanks for taking the time to make life easier for many of us who have been muddling through the differences for awhile now!!!
(although I still like to muddle from time to time!!) Title: Re: Frequently Used Lapidary Terms Post by: mirkaba on November 16, 2012, 08:48:10 am Great post Bobby1! Very nice cabs. Especially like the Montana Agate. The Montana Agate is generally called 'Montana Moss Agate' even though a small proportion actually shows moss like inclusions.
Title: Re: Frequently Used Lapidary Terms Post by: spiffman on March 05, 2013, 08:30:48 am Bobby, I'm new to lapidary for the second time in my life. One day I hope to be able to produce such wonders as you have here. My question is about the pictures tho. May I ask what lens you're using?
Thanks Tim Title: Re: Frequently Used Lapidary Terms Post by: bobby1 on March 05, 2013, 11:09:49 pm I'm using the standard 18 - 55mm lens that the camera came with. I use two photoflood lamps to light the cabs, a small plastic gizmo to hold the cabs above the photo graidient background, highest resolution, hand held about 12" to 14" away, let the camera focus automatically and let it select the exposure. I then download it with Windows photo programs and to get it up real close I crop the photo fairly close to the cab. I don't have nor use a macro lens.
Bob Title: Re: Frequently Used Lapidary Terms Post by: Rockoteer on March 09, 2013, 06:14:47 pm I most definately(sp) need a new camera... yippie24 Title: Re: Frequently Used Lapidary Terms Post by: SEW1950 on March 23, 2013, 08:13:50 pm Thanks much for taking the time with the basics, as a newbie on my first day I have already, and painlessly, learned some more. If I could very mousily, humbly, earnestly, (alright, whiningly) ask that you include pronunciations with some of the terms? Still remember the time in a rock shop when I pronounced chalcedony like 'chalice' and 'stoney'. Almost got laughed out all the way to the sidewalk. Required therapy.
Title: Re: Frequently Used Lapidary Terms Post by: spiffman on March 29, 2013, 04:00:40 pm Hey Bobby, I read your reply the day after you answered my question and as I was going through here again to help myself remember the lessons here i saw I never thanked you for your answer. I would add that I have pretty much the same set up as you do only I don't have the wonderful gems you captured. After years of landscape and portraits... man, taking pictures of rocks is making me stoned dancer27 , no really i'm struggling with these &%$* things... but love every minute of it....
