Testimonials

  • Hi Isaias, the two specimens arrived today, and I am thrilled with them!!. I think I made a hell of a choice. Wow, there wonderful, Thank You!!!. I had no idea the museum specimen was as old as it is, and the Fluorite on quartz, I don’t think I’ve ever seen one in quite that form and shape before! WOW, I’m very impressed!! Thanks so much, Scott.
  • Hi Isaias, I can’t say this about many mineral dealers but the few mineral specimens I’ve bought from you have exceeded my expectations and are definitely a fair value for the money. I wanted you to know this because usually people contact only to complain.  Thanks! Margaret Willis
  • Thanks! I received the piece today in good condition. I had been admiring that fine pink Himalaya tourmaline on your site for some time now. I feel fortunate to have been able to finally purchase it. Ironically, I live just a mornings’ drive from the old mine site- you might say that this well-traveled piece has come home… Best Regards, Bruce

  • Hi Isaias, I received the sapphire on calcite today (only three days after ordering, and I live about as far away from you on the continental US as you can get), and I haven’t been able to put it down! I haven’t seen a sapphire like that before, and I just had to snap it up. Thanks for consistently providing the best minerals on the Web, at relatively accessible prices in such an oft-inflated market. I’ve already made a prioritized list of my next orders from you! Best, Sheelin
  • Just letting you know that the wulfenite arrived today in great shape. It is a very beautiful piece and fits my collection perfectly. Thanks! John H.
  • Good Afternoon. Specimen arrived in the noon mail. It is an outstanding sample. Have a great day. Lee
  • Well, with that kind of provenance, I’ll certainly take it then. It’s a BEAUTIFUL piece and I’m no longer concerned about it’s origin.
    Last night, I was also looking at that red topaz on matrix from Katlang in the Barlow book, where he makes the statement that gem red/pink topaz on matrix are “non-existent”, so that certainly helped with the decision. Nice new group of rhodochrosites on your site. Hope to do business with you again soon as I’ll be looking at your site on a regular basis now, and we’ll have to meet face to face in Tucson. John S.

  • Hi Isaias, I just wanted to let you know that the Chinese tourmaline specimen arrived yesterday and I’m really happy with it. Its just a pity the smaller crystal had a broken termination otherwise it would of been even better. But I’ve been trying to get hold of one of these rare locality tourmalines for some time, so that’s another specimen to cross off my wants list, many thanks. I’m looking forward to doing business with you again soon, Regards, Paul Nicholson.

  • Hi Isaias,  I love the azurite/malachite layer cake. Thanks, Bob Byers
  • Hi Isaias, I’m writing to tell you how pleased I am with the blue-cap tourmaline I won on October 17 on mineral-auctions.com. The specimen was from the Tourmaline Queen Mine, and, although I could not tell from the auction pics, I am certain now after examining the crystal in person that this crystal came from the famous 1972 “blue cap” pocket. Its termination is a gemmy transparent blue and you can see straight down the c-axis into the reddish-pink core. It has all the characteristics of the larger, five-figure priced cabinet specimens that have made their way into magazines and books, but in a great and affordable TN size. I have about a dozen Queen Mine tourmaline specimens of many shades and colors, and even though this is just a TN, it blows the rest of them away! It’s just amazing how you found this specimen, because these 1972 pieces are very hard to come by. It’s definitely worth more than what I paid! I couldn’t be happier to own a piece of mineralogical history, so thank you so much for giving us collectors a chance to bring it home. It’s been great doing business with you for all these years. Best wishes, Josh Baimel
