When I first saw this lemon-yellow crystal, I thought it was a particularly intense orthoclase from Madagascar. I next guessed a bizarre twinned Dolomite from Brumado. I only drifted to guessing Montebrasite/Amblygonite on try #3. This is a stunning crystal with a color, luster, and gemminess that is WAY beyond anything you normally see for the species. It is fat and, I believe, twinned. It has an intense yellow-citrine color to it. Steve Smale, before exchanging this to me in a deal, had owned this for some time, and got it directly from the eminent dealer Carlos Barbosa (now deceased). He considered this to be the finest crystal for his taste, of the species. While there may be larger examples, for sheer quality, I have not seen better either. Note that this piece was analyzed to be sure it is in fact Montebrasite, and not Amblygonite. This specimen was featured in the exhibition "MINERAL DREAMS: Brazilian Gem treasures" at the Munich show of 2010. Joe Budd Photos - and yes, the color is absolutely accurate and incredible!
