i should add that i only bought a diamond thru them. i was lucky enough to have my grandmothers engagement ring given to me by my father to use for my proposal. the diamond was small and i wanted to upgrade the stone. from what i remember, it bought a 0.33 carat, internally flawless and super ideal cut and f colour for around $1800 thru brilliant earth. we received the order within days and we were completely happy with their service and diamond quality. to get the ring fit to the new stone, we brought it to jewels by design (downtown calgary) to have the shank replaced and the diamond set, which cost about $300 in total.
