Before you buy diamonds . Ask them to let you see the diamonds under UV light(their little magnifies have this option). I purchased 2 rings(sale price £5000/£2000) Plus 2 bracelets sale price £5000 each. They GLOW green. This indicates cheap diamonds. There are 3 diamonds on one of my rings that are pure green, they actually look like pieces of plastic under UV light. From what I gather, these SHOULD NOT be used for jewellery. Cheap as chips comes to mind!!! Puts me in mind of Ratners. They show you the jewellery under nice shiny lights, makes them sparkly. Only once you see quality jewellery against theirs do you realize "they ain't that sparkly
