that is absolutely amazing and stunning. I collect minerals in real life and I have a very nice collection in glass display cases with lights. I love looking at them. Mother Nature never ceases to amaze me.
I'm afraid I don't know anything about the dynasties. Are you using the 'display case by blingbling' ? I've got one of each mineral and gem in my sims family shared inventory in build/buy. I don't have the space on his lot to keep them all out. How did you manage it. I originally started to have each of the cuts for each of the gems, but I quickly abandoned that because it just filled my inventory with to much stuff. But it looks just wonderful in your shots.
Pam did fantastic job there as she did it without a single cheat involved! I have my own full gem collection
shared here which includes 25 different gems in 13 different cuts, all large but I used cheates for motives and exit without save which is not allowed in Dynasties. In
this topic our member EnglishRose shared a wonderful way of displaying gems on shelfs, while I like to place them on ground with moveobjects on and with holding Alt - that way you can put them on piles anyway you want.
I used my own small ugly and empty island that is good for fast loading and testing purposes, while there are quite a lot of small custom made worlds around the community. Still if your PC is fast enough and you like to play with your Sims while getting this collection then stick with your current neighborhood.
