Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - DIAMENT offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Diament* is one of those wrecks that truly tells a story. Sunk in 1942, a German war prize that met its end on Dog Nest Rock, it’s now a pretty well-scattered collection of metal, but that’s precisely its charm. We love drifting over the twisted plates and sections of hull, imagining the ship's final moments. It sits in relatively shallow water, so you get good light penetration on most days, illuminating the kelp-covered debris. What you'll experience here is less about penetration and more about exploration. We spend our time poking around the jumbled metalwork, watching conger eels peek from dark crevices and schools of pollack flit through the gaps. You’ll find plenty of crabs scuttling amongst the rocks too. This site is brilliant for macro photographers or anyone who enjoys a gentle drift over history. It's a great second dive, or a relaxed first dive if you're not chasing anything too deep. Look for the distinct boiler, it's usually a hotspot for life.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
