Diving the Blue Diamond wreck, San Andrés

Blue Diamond, which some guides simply call The Diamond, is the hull of a cargo ship sunk off the west coast of San Andrés, towards the south. Over the years it has become covered in coral and works as an artificial reef, home to reef fish and some large specimens. If you like wrecks, it’s a dive that blends history and marine life.

What the dive is like

You dive around the hull of a sunken cargo ship, now covered in coral. References don’t agree on the depth: some put the wreck at around 12 m, others at 14 m and one goes as far as 28 m. It depends on the exact spot and the route; the guide will explain the profile before you descend.

What you’ll see

Sergeant majors, damselfish and parrotfish move around the hull. Large groupers, moray eels hidden in the structure and, now and then, a reef shark are also mentioned. For wreck photography, the shapes of the ship give you plenty to work with.

The story of the ship

Here it pays to be cautious. Several sources say the ship was sunk on purpose to create an artificial reef, but there is no reliable information on its original name or the date. What is clear is that it’s a cargo ship and that today it’s part of the underwater landscape of the west coast.

Level, depth and conditions

Certification and some experience are recommended; depending on the planned depth, it may call for Advanced level. A wreck demands good buoyancy so you don’t knock the structure or stir up sediment. On Siete Azules trips, whether or not we go is decided according to the sea, the current and the group’s level.
