How Many Side Stones Should I Choose?

The amount of side stones to go for is one of the first and most important decisions to make in the overall design of your engagement ring. The most common choice is undoubtedly a Three Stone Engagement Ring design, which will mean choosing two side stones. The second most popular option nowadays is to opt for a five stone engagement ring which as the name suggests would entail two side stones on each opposing side. The truth of the matter is there is no limit to how many side stone diamonds you can surround your center stone with, but it’s important to note that the more side stones you incorporate, the more difficult it will be to achieve your intended goal, as each diamond piece, however small, will require a separate ring setting. That is not to say that more than five stone diamonds can’t work, but it does entail more potentially costly repairs in the future.

What Size Should Side Stones Be?

There are a number of factors that give side stones their desired effect. Proper size implementation is undoubtedly one of the most important ones. Three Stone Engagement Ring Side Stone Size Formula: As the most popular and time-proven combination, three stone engagement rings follow a minimum and maximum formula depending on personal preferences. The intended goal is to have side stones that aren’t big enough to take attention away from the main piece, but not too small as to not enhance it at all.

The general rule is between a minimum of half (50%), to two thirds the (65%) of the size of the center diamond. If you want to calculate with a higher degree of accuracy to consider a particular piece, you need to divide the average diameter If you opt for more than two side stones, it is a general rule that they should be quite noticeably smaller. If you choose the classic two side stones, one on each opposing sides of the center piece, slightly smaller will suffice.

How to Choose the Right Color for Side Stone Diamonds?

There are two major factors in choosing the ideal color for your side stone pieces. The side stone colors need to match one another completely, or as close to one another as possible. The color of your side stones should be a grade lower than the color of your center stone diamond, but not more. They most certainly should not be higher in their color grade than your center stone, as that would ruin their intended goal of enhancing its qualities. A G Color Princess Cut for example, should have H color side stone diamonds accompany it.

What's the Best Clarity for Side Stones?

It is always important to begin with the basics when it comes to clarity in side stone diamonds. Look for side stones with clarity that is eye clean. What do we mean when we say eye clean? diamonds that have inclusions and various imperfections that are not visible to the naked eye. That is not to say that you have to opt for non economical clarity choices. In fact, depending on the ring settings used, and the positioning of the inclusions, you can save a substantial amount of money while hiding these imperfections. The clarity between each individual side stone should be as identical as possible, and no more than a grade lower from one another.

What are the Best Ring Settings for Side Stone Diamonds?

Choosing the right settings for your side stone diamond ring is one of the most important decisions to make, as side stone diamonds can loosen over time if you opt for a setting that is not suitable to protecting and maintaining them. The safest choice is undoubtedly going the most classic route which is using the classic prong settings. Why? Because they’re the perfect blend of securing stones, and enhancing their brilliance instead of diminishing it. They work by extending a metal extending from the bottom, then curved in a subtle way over each stone. There are dozens of variations of prong settings, meaning you don’t have to settle for one style only.

Other popular choices include Bezel and Cathedral Settings.
