This page is special, as we have included in it only those specimens from the Martín Oliete Fontela collection.

Martín is a very pleasant artist who has specialized in prints, ex-libris and old books, he is also a gemmologist. He has combined this with many years of collecting and dealing in minerals, so he is well known by all those in Spain who are interested in minerals, especially those from the Madrid area, which is where he lives.

Martin collected minerals for over 35 years. Towards the end of the 60s, when he first started, mineral dealing had hardly been heard of in Spain so it was limited to a small group of specialized people in the major cities, above all in Madrid and Barcelona. In those early days very few high quality specimens got as far as Spain and of course there were no shows at which one could buy specimens.

Given this, and his decision to build a good collection of worldwide minerals, Martin found that he had to travel to the USA to get hold of the type of material he wanted. The result is a collection in which his ability to select fine specimens shines through, especially as it was combined with the large number of specimens he was able to see each year.

His focus was, luckily, on what we might call the 'modern style' of specimen, that is to say: not that large and, if possible, perfect and esthetic. He also aimed to collect as diverse a range of species as was possible, instead of focusing in on a few minerals.

In February 2002 Martin decided to sell his collection for personal reasons and, due to our old friendship, he offered me the chance to buy as much of it as I wished. It was an easy decision for me, so we quickly met and I bought what for me were the best pieces (in my opinion) from his collection. These then sold very rapidly at shows and over the web.

This page is now a small tribute to this collection, and at the same time it gives our visitors the chance to see some of the collection we sold.

I hope you enjoy them as much as I did when I first selected them!

FC76: A curious specimen. It is a Dolomite totally covered (but not pseudomorphosised) by a thin chocolate cover of iron oxides. First impressions when you look at the specimen are: nice Siderite! When you look more carefully you will discover that the primary crystals are really white curved Dolomite crystals totally covered by a lustrous, brilliant, colorful coating. Something different!

Rhodochrosite with Quartz

FC37B9: Before the recent major finds of Rhodochrosite in Alma, one of the most popular localities for Rhodo in USA was the American Tunnel.

Oliete's collection number: 335, bought in 1973 from V. Yount
Andradite (Garnet).



FT59C6: Attractive Calcite - it looks as if it was zoned pseudomorphosed by snow. I'm sorry, but it is so unusual that I cannot say anything more scientific!

Quartz (variety amethyst)

FG90: Amatitlan gave the largest doubly terminated Amethyst crystals in the world. Unfortunately most of them were damaged with broken or significant dings at the top of the crystals. Just a few specimen were saved in good shape. Again, Martín was in the right place at the right time and luckily he got a very esthetic one without significant damage. Plus this specimen has two main doubly terminated crystals joined by other smaller crystals. As you can see in the photo the specimen looks great!

Oliete's collection number: 207, bought in 1996
Quartz (variety amethyst).

FC37B8: Really huge (for the locality) Topaz, with some other interesting things: the color is more 'chocolate' than usual; the transparency is better than usual; and it shows a curious inclusion, probably by sandstone, in its center, very visible due its high transparency. One of the best for this locality, in my opinion.
Tepatate, San Luis Potosí  Mexico

Specimen size: 4.2 × 3.3 cm = 1.65” × 1.30”

Gartrellite with Mimetite

FC56: A major specimen. Gartrellite is a mineral species that was recently discovered (1990) and its presentation up until now is not that great under common esthetic standards. Usually it is presented as dull crusts of fine-grained coatings, cryptocrystalline or as incrustations, so basically not beautiful. One specimen from Oliete's collection was labeled as Arsentsumebite, but I was suspicious that it wasn't. I ordered a double X-ray and difractometry test and the result was Gartrellite: bingo! This particular specimen is probably one of the world's nicest Gartrellite and it is shown for first time to the mineral world in this update. Gemmy minor Mimetites are also present, completing a world class specimen.

Chalcocite with Calcite

FA77: Again, something extremely unusual from Martín. This well formed Chalcocite which is aerial on the Calcite matrix comes from Chile. On Oliete's label the location is written as being Chuquicamata. After hard investigations about Chilean mineral localities I'm able to tell that it must came from Copiapó and I'm also able to say that I have never seen anything similar in my life and I'm sure that not too much other people have either. Well, it is good, sharp and extremely original.

Atacamite on Agate.

FZ16: As a collector specimen this Atacamite shows something different from other specimens. In this particular case it is the unusual presentation: it is on top of Agate, with a wonderful contrast between the lustrous green Atacamite crystals and the banded grey Agate. Different!
