SPECIAL ANNOUNCEMENT: NEW COLLECTION ACQUIRED!

We are excited to announce that we have purchased the collection of Willard W. Wulff (1904-1998) of Colorado Springs, Colorado. Wulff was a fixture in the world of Colorado field collecting, and was one of the founding members of Colorado Springs Mineralogical Society in November of 1936. His contemporaries included dealer Lazard Cahn, famous field collector Edwin Over and the esteemed collector George White. Starting this week, the majority of Wulff’s 1000+ piece collection will be offered over the coming months in the auctions. Most specimens are accompanied with Wulff’s signature typed 3x5 index cards, and some specimens date back over 70 years! A great “time capsule” of a collection with plenty of interesting, unique and worthwhile specimens to add to your own collection.

We found a link for an autobiography that Wulff wrote in 1985 on the Colorado Springs Mineralogical Society website. Click here to read it.



This week’s auction is filled with a great selection of pieces with specimen from world famous classic localities, along with contemporary treats, native elements, rarities, gem crystals and more! We’re not just listing the standard “20 species” from week to week, but an eclectic mix of interesting minerals, classic material and hard to find species that appeal to wide range of collectors. You will see a lot of exciting material in the coming weeks and months with plenty of desirable specimens for all tastes!


Some of the highlights from this week’s include:
1. A fine quality matrix Sapphire from Madagascar
2. Beautiful rich green gemmy octahedral Fluorite on matrix from South Africa
3. A lovely Diamond crystal from the Miba Mine, Democratic Republic of Congo
4. Classic old time Libethenite from the Type Locality!

SPECIAL DENVER EVENT: LARGE GEMSTONE & CABINET SPECIMEN LIQUIDATION AUCTIONS - end Sept. 22, 2016

Ends Sept. 22, 2016
at 6:30 PM (Central Time Zone)

note: THESE SPECIMENS WILL SHIP AND BILL SEPARATELY
FROM OUR OTHER AUCTIONS, EARLY NEXT WEEK


Unlike most of our auctions, which are pooling specimens from multiple sources and huge collection buyouts, this one is featuring two lots that we decided to auction rather than to take to Denver to liquidate for the owners to dealers:

1) CABINET SPECIMENS from one longtime Spanish friend and collector who is thinning down his collection for a retirement move, and offered them up for auction (against my own opinion that he might get more selling them one by one over time, retail!). His feeling was that the money they yield doesn't matter, because this was the best way to move them all without "heartbreak" from selling one by one after he spent 40 years acquiring them. I hope we can show him how they go to good new homes!

2) A small group of a half dozen LARGE GEMSTONES !

$25 and $10 RESERVE GEMSTONE CONSIGNMENT AUCTION - Ends September 15th, 2016
