If a construction company is called Bluestone, what sort of impression it gives you?

I need some suggestion for a easy-to-remember business name.
I like stone and I want to give my customer an impression that the building we constructed and sold will be a good secured investment.

Bluestone is a chemical used to keep pools clean in the 60's. It made the junky stuff fall to the bottom. Think more in terms of Rock Solid Construction.

It means to me you could have the capabilities to construct another Stone-Henge; THE GREATEST feat of construction engineering ever accomplished. This excerpt copied from Wikipedia I hope says it all. "The inner circle Stonehenge 3i
Archaeological excavation has indicated that around 2600 BC, timber was abandoned in favour of stone and two concentric crescents of holes (called the Q and R Holes) were dug in the centre of the site. Again, there is little firm dating evidence for this phase. The holes held 80 standing bluestones (shown blue on the plan) brought from the Preseli Hills, 250 km away in modern day Pembrokeshire in Wales. The stones, which weighed about four tons, consisted mostly of spotted dolerite but included examples of rhyolite, tuff and volcanic and calcareous ash. Each measures around 2m in height, between 1m and 1.5m wide and around 0.8m thick". Therefore that is why I think that it is an awesome name for a construction company . Go for it...
