Final answer:
Canadian diamonds command higher value because they are mined adhering to ethical practices, have strict environmental standards, and come from conflict-free sources, enhancing their allure. Additionally, the stronger Canadian currency can influence the cost when exported.
Step-by-step explanation:
Canadian diamonds are often perceived to have a higher value compared to diamonds from other countries for several reasons. A significant factor is the ethical mining practices and strict environmental standards upheld in Canadian diamond mines which contribute to a more positive image and increased demand.
Canada’s diamond mines are known for having minimal environmental impact and for being conflict-free unlike some diamond sources which have been tarnished by associations with human rights abuses and conflict financing. Also the marketing of Canadian diamonds as originating from pristine and untouched northern landscapes adds to the allure and perceived value. Moreover the Canadian dollar often being stronger compared to other currencies can play a role in the higher cost of Canadian diamonds when exported.
