My first decent-sized nugget

I'm basically a new guy here, even though I have posted a few times. I thought you guys might enjoy my good news - bad news - good news story.
Last weekend I went to a family reunion in Bakersfield (thanks in advance for the condolences - enjoyed the reunion, but not Bakersfield), and on the way home I spent Memorial Day beeping in northern Nevada. As I was driving out to my prospecting destination, I noticed the shoreline benches of ancient Lake Lahontan, which covered much of northeastern Nevada during the last ice age. When I got to where I was going, I concluded that I was on the bench just above the highest shoreline. After beeping around on the bench for a while, I dropped down one of the little ravines that cuts through the old beach. I noticed that there were outcroppings of tufa (calcium carbonate deposits) on the sides of the ravine, apparently formed when this was the shoreline. I got a faint target on my GP3000 in the soft dirt on the side of the ravine, just above the bottom, and started carefully digging. By the time I got down about 10 inches, the detector was screaming at me, and I could tell from the loosely cemented rocks I was digging up that this was no bullet. My elation turned to despair when I hit a layer of solid rock. The entire bottom of the hole was rock, and I don't mean shale. I had no real rock-breaking tools with me, so I tried to find an edge that I could dig under and pry up. No such luck. I turned my coil on edge and located the nugget horizontally to maybe a 3 inch circle, but I had no idea how deep it was. It might be just under the surface where I could damage it, or it might be 3 or 4 inches down where I couldn't reach it. I finally started chopping and pecking and pounding around the edge of where I thought it was, and after about 10 minutes of this, I saw some vibration, so I knew I had cracked the rock. I broke out a couple of chunks, and one of them made the detector scream, but I couldn't see any gold in it. I wiped off the wet dirt that had clumped on it when it came out of the hole, and there was this gleam! Below (God willing) is a picture of the hole, and one of the nugget still embedded in the tufa. I just noticed that I had my finger in the picture.

I guess that's why I'm not a photographer.
I'm trying to figure out what to do with the nugget. Would you keep it as it is, or etch it out? If you decided to remove it, would you use acid? If so, what kind, an how diluted?

BTW, this is only the second nugget (the first was a little one last year at Rye Patch) I've found with my GP, and I've had it about a year, although last summer was my first one in a new house, so landscaping and honey-doos mostly kept me out of the gold fields.
I also have about a dozen little boogers I found with my GB2. Hopefully I'll get out more this year.
