The family visited two gem stores today, about 20 minutes southeast of Perth in Orange Grove. From what we gathered, it was a family business that had a falling out and they split the store into two separate businesses, located right next door to each other. Kind of strange...

Both stores are on Dale Rd. Soklich is the first one that you will come to and it has the largest, biggest, most impressive rocks I've seen. When we visited, there was a $100,000 amethyst piece that was really impressive to look at.
The store was loaded with amethyst cathedrals of varying shapes and sizes, one looking very much like a hand reaching up out of the floor.
Soklich had many pieces of

WA mined tiger iron, from small chunks to massive 1m wide slabs perfect for hanging in the entrance way to Rio Tinto or BHP offices. Of course, the $10,000+ price tags and the unimaginable shipping costs meant none of these items would be coming back home to NY with us.
The Gemstone Factory was a pleasant surprise as well. The store has many different type of gems, crystals, and the like. The prices at Gemstone Factory were much lower than Soklich - it was obvious that the businesses, although co-located, served different clientele. Nothing was as big as Soklich, but we picked up about $150 of pieces so we could bring back a piece of Australia. Several Tiger Iron slabs, some Jasper and quartz.
The stores are a nice stop if you're hiking in the Armadale/Hills area. Take a look!
