Not so long ago, buying an engagement ring was a straightforward process of picking a ready-made piece off the rack or selecting a precious metal and a diamond and having it set into a pre-fabricated ring casing. These days, though many retailers offer this quick and speedy service, the sheer variety of available design choices can create confusion and hesitation for the customer. Out of frustration, the same customer can end up purchasing a ring that they aren’t entirely happy with or end up spending far more than they hoped for.
