As fair buyers of diamonds and jewelry from our community, people drive from all of Southern California to sell or trade in their diamonds with us. We see this part of our business as a service and can pay more than other buyers while offering our clients prices that cannot be matched by chain, online or local competitors. If we’re able to match your perfect diamond with one we’ve purchased from the community, you’ll have money left over.
