WEALDSTONE'S play-off hopes now hang by the thinnest of threads following defeat by fellow promotion hopefuls Tonbridge on Saturday.
Stones were second best in the first half, during which they fell behind to an Ade Olurunda strike and though they improved after the break, a second for the hosts 10 minutes from time ended their 12-match unbeaten run.
It leaves Gordon Bartlett's men 10 points off the promotion places with just seven games remaining.
Frannie Collins and Jake Beecroft went close in the first 10 minutes for Tonbridge, and the Angels were closer still when Olurunda's shot was palmed by Jonathan North into the path of Collins, whose follow-up effort from close range was off target.
However, the hosts were not denied for long, taking the lead on the half hour as Chris Piper got to the byline and pulled the ball back for Olurunda to force home.
Yet Stones could have been level by the interval as Joe Benjamin hooked the ball into the six-yard box for Danny Spendlove to head goalwards, but the winger's effort was blocked to safety by Lee Worgan.
Callum Martin replaced the ineffective Benjamin at half-time and the striker was soon in the thick of things as Kurtney Brooks' powerful shot hit him en route to goal and deflected just wide.
Stones' best chance of a leveller came on 65 minutes when Peter Dean's clever flick released Spendlove once more, but again his shot was parried away by the advancing Worgan.
Angels who had been quiet since the interval went close again when Scott Kinch's superb 30-yard volley was tipped round the post by North.
Nevertheless, Stones' fate was sealed 10 minutes from time as Olurunda's header from Jon Heath's deep cross crashed off the bar into the path of substitute Carl Rook, who nodded in from six yards.
