Also known as Billy Diamond's Bridge Stone Circle, Glenquicken is an oval stone circle with a single central pillar standing 1.6 meters tall. The central stone is cobbled. The outer ring was originally formed from 29 stones, but today only 28 remain, with a gap to the western side indicating where the stone was removed. The circle has a 28-meter diameter, with the stones being taller on the southeastern arc.

The British archaeologist Aubrey Burl has referred to Glenquicken as "the finest of all centre-stone circles".

Two other stone circles to the northwest are no longer visible. There is also a cist burial to the west, it is thought to have originally been covered with a cairn which has now been removed.
