The person behind GreekRocks is Christos Spiromitros. Chris is a geologist, mineral collector and mineral dealer who started selling minerals online in 2006 and started collecting minerals in 2005. Chris lives in Thessaloniki, Greece and has a beautiful family with his wife Joanna, sweet son George and stunning daughter Konstantina. He keeps a second business (jewelry, accessories and some minerals too) together with his wife Joanna (called JCrystals) and he can be found during most business hours at their shop downtown Thessaloniki, in Grigoriou Palama 4 street (no mineral gallery there though!).

• Online Presence

Chris has owned greekrocks.com since 2007 (the website has been offline for a 2 year period as we sold our entire website inventory). Now(early 2025) we are back online! Chris has participated in several online auction platforms in the past but now only on MineralBids. Social Media are a must nowadays so Chris sells both via Facebook and Instagram (follow!)

• Mineral Shows

GreekRocks participated 4 years in a row in the Munich show 2014-2017. Tucson 2015 & 2016 too. Since covid, we decided to continue doing business online. In our old shop/storage space/lab we also keep a showroom where we accept visitors/buyers by appointment only.

• Accomplishments

We have handled some of the finest Greek minerals that have ever been discovered,  and supplied some of the most reputable mineral dealers and collectors with fine minerals from Greece over the years.

• MineralBids

We are proud for our new MineralBids – Mineral Auctions & Marketplace! A platform for trusted sellers and serious collectors with a rock-solid auction system!
