Owen's Homepage and Mindat Auction ' How to' and T&C

Registered member since 12th Feb 2012
Thanks for dropping by my home page. Life sometimes goes in phases. After a career in UK government service, I made a mid-life change, starting my own business in the security field. Some 20 years later, I retired from business and now fill my days examining and studying gemstones, improving my knowledge and understanding of them and about them. I live in a rural area of the south of England, not many miles from the ancient city of Salisbury, the megaliths of Stonehenge and the surrounding Iron Age hill-forts.

My gem stone interests extend across some 300+ minerals in their gem varietal forms. It extends also the range of minerals that can be found as inclusions within host gem crystals, as these can yield much information regarding are the origin of their gem crystal hosts and some of the treatments to which they may have been exposed to improve their desirability. I also have a subsidiary interest in learning about synthetic and simulant gems and their differentiation from those created through geological processes.

To assist in this study, I have a growing reference library and a small lab equipped for:
- Refractometery.
- Microscopy (both in air and in liquid immersion).
- Polariscopy (stand alone and in conjunction with microscopy).
- Spectroscopy.
- Gravimetrics (weighing, to you and me). This extends to a supplementary use of heavy liquids and I hope, this year, to augment this area of study through the additional testing of the magnetic and diamagnetic properties of minerals.
- Mensuration (dimensions and angles).
- Photomicrography and Macrography.

I don’t trade in stones but I do have a large collection gem specimens, mainly of collectable or study interest, that ranges from natural crystal forms, through samples of gem quality rough, to cut and polished stones. Many of these I shall be putting up for auction through the Mindat auction site. Which makes this a very handy place to set out for prospective Mindat auction buyers the terms and conditions I can offer. These are designed (I hope!) to make life safe, simple and to give prospective buyers the information they should have before making a bid for one of my lots.

Do please feel free to contact me on any topic, by PM or by e-mail, direct to

One of the particular pleasures of the study of minerals and gems is the people it brings one into discussion with.

Thanks again for stopping by.

- Aggregation of Purchases for Shipment. To minimise shipping costs, a buyer may choose not to have goods dispatched promptly following each invoice payment but to allow items purchased to be held on account by the seller for any specified period up to 90 days from date of purchase, so that a single consolidated shipment can be made of several purchases made over time, subject to the following conditions:
