This cluster solitaire diamond pendant with halo is an all-time favorite. Besides the fact that this pendant is stunning, it is also an interesting option price wise. Because, when you look closely, you see the center stone of this pendant actually consists of four separate diamonds. We call this way of diamond presentation ‘cluster’ or ‘illusion’. Because the four “fancy shaped” clustered diamonds create the illusion of one large brilliant cut diamond.
This diamond pendant is 18 karat white gold. The four diamonds in the middle are together 0.55 carat. They have a Top Wesselton color and a VS clarity. The halo around the clustered stones consists of 20 diamonds. These diamonds are brilliant cuts. They have the same Top Wesselton color and VS clarity as the diamonds in the middle.

This flower-shaped pendant contains seven diamonds. That is why we also call it a 7-diamond pendant. The thing that makes this pendant different from many other halo or flower-shaped pendants is the size of the diamonds. Normally, the diamonds around the center stone are (a lot) smaller than the main stone. But in this pendant, all seven diamonds have the same size.
