Solitaire and Tapered Diamonds
The diamond at the center of this piece is a stunning 3.71 carat stone in a round brilliant cut. Its sparkle is enhanced significantly by the accent diamonds running down the shank, four on each side. These taper in size as they move away from the main setting, giving a smooth flow to the overall design. Diamond Engagement Rings
Shared Prong Setting
This ring utilizes shared prong settings for all diamonds, which means that each set of two prongs is holding one side of two different stones at the same time. That configuration creates a more open look that allows the beauty of the diamonds to really shine through. Especially when viewed from the top, the stones in this ring take center stage thanks to their settings and configuration.
Square Shank
Because there are so many large stones in the top half of this ring, we recommended the client go with a square shank. This helps to keep the ring upright on the finger, which makes it an especially good choice when there is a lot of weight at the top of the piece.
Also due to the number and size of stones involved, we made the band itself from platinum, which is quite strong but lightweight. That allowed us to set the stones securely while not adding too much to the overall weight of the ring.
Custom Design
If you like this ring but want to tweak the design to make it better reflect your individual style, our experts are here to help. One option for customizing this design involves substituting a different gemstone for some or all of the diamonds. Or we could use a different type of setting to give the ring a more vintage or contemporary feel, depending on your preference.
