A simple "diamond" solitaire in various sizes and lengths on a sterling silver chain.  A beautiful claw set stone which you genuinely can't tell isn't the real thing. 

Solitaire pendant sizes: 5mm-8mm

Chain lengths: 16", 18", 20" (longer lengths available on request)

Should you require a larger solitaire please get in touch and I will endeavour to get one for you in either 9mm or 10mm.
