Thanks for noticing. It's my first attempt at translucency. Actually no that's not a real gem. It's just some Tamiya clear gloss red over Citadel Mithril Silver.
WaHey! Saucy mini. Youve got a nice translucent effect going there. The photo doesnt do you any favours... too much light or flash (turn it off). Thats a "real" gem in the staff isnt it?
