Greetings to gem and jewellery industry professionals

My name is George Christianos and I am the managing director of Opals By Emmanuel Christianos Pty Ltd. We have been in the open mining and wholesale business since the late 1950s and three generations ago. We started mining in Coober Pedy with my grandfather and in the 1970s my father moved the business to Mintabie in South Australia. In the late 1980’s and 1990’s, he added Lambina in South Australia. Later in the 1990’s, it was moved back to Coober Pedy as the permitted work area in Mintabie was not being expanded and the deposit and the permitted area no longer coincided. Around about the year 2009, I took over and moved the business to Lightning Ridge where we remain to this day, chasing that elusive black Opal. From 2009 through 2019, we maintained a fulltime sales and marketing office in Shenzhen, China, from where we partook in over 200 gem and jewellery exhibitions. You can read up on a bit more history on our company website CHRISTIANOS.COM

Welcome to our new online inventory database. Our online database is set up to provide wholesale access to the trade and is not available to the public.

Your level of access to our online database shows you the wholesale price.

The combined shopping cart/product comparison page allows you both to do a comparison of different items as well as to select items for memo or purchase. Memoing can only be done by prior arrangement. The cart is submitted here online to let us know what goods are required and where the goods need to go. No transactions are actually completed online.

If you're interested in some lots and you need more pictures or information or videos, please send us an email at opals@me.com referencing the stock number and what you would like to know.

We are here to assist you to market and sell Opals as it is to our mutual benefit. If we can assist in any way or provide materials etc please make contact and let us know.

As this website is expanded, we will be providing Opal knowledge and Opal marketing tools for some training and Opal familiarisation for your staff.
