Buying an engagement ring which has already been preassembled is about as romantic as putting a quarter in a gumball machine and hoping you’ll love whatever comes out. It’s a bit of a gamble because in many cases you’ll come across a band that you’ve fallen in love with but a diamond which is not exactly what you’re looking for or vice-versa. An engagement ring should be personalized to best suit you and your tastes. A semi-mount offers that freedom to customize and build your engagement ring.

But what is a semi-mount? A semi-mount is a ring which has all of the side stones and details set, but is still missing a center stone. Semi-mounts offer you the freedom of choosing the right center stone for you. Most engagement rings are set with diamonds, but a semi-mount offers you the option of choosing something more unique and meaningful for you. Or if you already have a diamond, perhaps an heirloom piece, this alternative allows you showcase it. You have the last word in what you choose to make your focus.

There are a few things to consider before choosing a semi-mount. If you’re opting for a special shaped gem, such as heart or marquise, ask your jeweler which semi-mounts may be the best fit. Most semi-mounts are very flexible and can accommodate many different sizes and shapes but it is best to consult your jeweler first. Find out which rings can accommodate the size and shape you have your heart set on.
