Many errors seen in jewellery - 3 photos

Here is a troubling Emerald ring, why am I anxious to discuss this expensive Emerald setting? Where is the "V" claw on the Pear-shaped point?

 I would never allow anyone to wear this ring with no "V" claw protection". Even now I can see that 'the point' of the stone is damaged and as well broken off.

 The four claws have little symmetry to the finishing, as the front of the 4-claws has a sharp front edge.

 This is a 'poor finishing', why am I writing this? The front of each claw will 100% catch clothing. 

 I took a quick photo of a ladies' diamond pendant. I saw problems and asked, "where did you buy this diamond pendant?" "Oh, it belonged to my Mother and I wear it all the time", (I then kept my comments to myself).

 

 Just where is the "V" claw to protect the diamond? There wasn't any, plus the four very small claws are giving little ongoing protection in case the Pear-Shape diamond gets loose and falls away.

 I'm not criticizing these designs, but preventive measures and safety were not on the manufacturers "to-do" list.
