the name suggests, in cluster setting, a bunch of mounted gemstones are clustered together. If it’s a diamond, then these groups of diamonds clustered together are set in a manner that creates an illusion of a big solitaire diamond. Since the smaller diamonds are set closely together, it creates a “cluster” effect, hence resembling a larger diamond. A cluster ring can have a large center stone or a group of smaller stones that are equal in size. Often, the gemstones in cluster rings form a geometric shape, such as a square, or a unique design, like a flower or starburst. It's not new that the cluster rings you will find in the market will have an antique look. If you compare cluster settings with solitaire settings, say in the case of a cluster engagement ring and solitaire engagement ring, then you will find that the cost of a diamond cluster engagement ring is much less than a diamond solitaire engagement ring, provided the total size appearance is same.
