Hi Rabbit, I am going to let you in oon a secret that has always served me well in my area of specialization - if a sapphire is set in 10k gold, it is a muddy, navy blue, inexpensive one. Same with rubies, emeralds, and diamonds. If you look at my listings, they are not for 10ct. Jewellery is valued based on the clarity and colour of the stones, the skill of the craftsman, and the weight of the gold used in the piece.  I only sell things I would wear, and with all respect, I would never wear the type of jewellery you are describing, and neither would my customers. And please understand that I am not without customers, just without eBay customers as of late. I really am passioante about what I do and this is not a scam, so no, I do not want your site - I am not interested in finding low quality mass produced items to sell as genuine estate peices to trusting customers. If you do not know the difference then maybe I am not looking for advice from you but you are of course welcome to post just like everyone else. 😃
