never bought my wife an engagement diamond, didn't have the money! For our 40th wedding anniverary went to buy a ring. Price 15000 to 25000QR for a really nice diamond ring. Enquired about certification as I did not want to buy an illegally mined diamond for which someones hands and feet had been cut off as in Sierra Leone etc. That cost 10000 QR extra. I was horrified that "blood diamonds" are on semi open sale in Doha. We agreed, I bought my wife a car instead, cost me 68000QR. What price principles?
