Denise, I always do Quartzsite first, I find prices there especially
for rough, far more reasonable. Many large dealers set up in both
places. Costs are far lower in Quartzsite, so prices reflect that.
I also know dealers buy in Quartzsite, mark up and sell in Tucson.
On the other hand, many Tucson dealers have never been near
Quartzsite. It all depends on what you are looking for.
For me personally, both are wonderful and worth doing. Teresa
