It will automatically center to the specified line width, and requires that the line be at least as wide as the diamond itself.

function show-diamond {
    param(
        [ValidateScript( {$_ -ge 11} )]
        [int]$LineWidth = 11
    )

    $range = [System.Collections.Generic.List[int]]::new()
    (1..11).Where{$_ % 2 -gt 0} | ForEach-Object { $range.Add($_) }
    (9..1).Where{$_ % 2 -gt 0} | ForEach-Object { $range.Add($_) }

    $output = [System.Collections.Generic.List[string]]::new()
    for ($i = 0; $i -lt $range.Count; $i++) {
        $MidPoint = [math]::Round(($LineWidth - $range[$i]) / 2, [System.MidpointRounding]::AwayFromZero)
        $String = '{0}{1}' -f (' ' * $MidPoint), ('*' * $range[$i])
        $output.Add($string)
    }
    $output
}
