Alessia Collection is different to most other engagement rings on the market in that EACH piece is custom ordered and produced. This means that any style of ring can be made to hold ANY size of center diamond. And each order is made to your specific ring size. All engagement rings are offered with perfectly matched wedding bands, available at any time either at the time of, or after your engagement ring purchase. We keep detailed records of all rings that we sell, down to ring size and setting size.
