Description

Detailed Description

A beautiful thumbnail-sized dioptase from Altyn-Tyube, the type locality for the species. The dioptase crystals are sharp, lustrous and intense green. The largest crystal, 2 cm long, is huge for Altyn-Tyube. This is an older specimen, acquired by Steve through his family in Hungary after the USSR was dissolved. In excellent condition, if you look for them, you can find two tiny surface chips on one larger crystal and one small crystal is chipped. Stands perfectly for display as photographed – this is a fantastic dioptase.


About Steve Szilard

Steve Szilard is a well-known and highly respected Canadian mineral collector who began collecting in1982. It may strike a chord with many of you that one of his first two mineral books was the Peterson Field Guide to Rocks and Minerals by Fred Pough – that was certainly true for me too (and my own copy sure looks as well used as it has been!). Steve is a skilled and accomplished field collector, having collected extensively in Ontario, as well as in almost all Canadian provinces and across the United States. Having travelled the world acquiring minerals in many countries, he has also attended many mineral shows – in particular, he has attended the Rochester Mineralogical Symposium for almost 30 years.  Steve has a long record of mineral community involvement and contribution, having been with the Walker Mineralogical Club in Toronto since 1985 (and a member of the executive for many of the years since then) – he has also been a member of the Scarborough Gem and Mineral Club, the Kawartha Rock and Fossil Club and the Canadian Micro Mineral Association. As you might expect, given his mineral collecting career, Steve is incredibly knowledgeable about minerals and many mineral-related subjects. He has always been kind and generous with his knowledge. Steve has enjoyed assisting in the activities of a great organization, the Young Toronto Mineralogists Club, including talks, using binocular microscopes, and field trips. It is a pleasure to be able to share his collection with you.
