Star 129 Diamond Center
The center stone in this piece is a 1.01 carat round diamond featuring the Star 129 cut. This is what allows it to display such brilliant fire, as this type of cut creates 129 precisely-placed facets to reflect light back out. That is compared to an average of 58 facets on a normal round brilliant cut stone, and 76 facets on a princess cut. Diamond Engagement Rings
Diamond Halo
Further intensifying the sparkle of this piece, eight round brilliant cut diamonds, which together total 1.06 carats, are arranged around the center diamond in a shared prong set halo. This grouping gives the entire center setting the appearance of a sparkling flower, and it brings subtle classical overtones to the piece as well.
Metal, Setting, and Gemstone Options
If you’re interested in customizing this piece, you’ll have many options to consider. For instance, switching to a rose or yellow gold for the setting and band could bring some vintage flair to the piece while adding a beautiful contrast. And substituting pink diamonds or sapphires for the stones in the halo would introduce romantic overtones while also reinforcing the floral themes already present.
Even if you don’t have the vocabulary to describe the piece you’re envisioning, we can help guide you through the custom design process, showing you as many examples and outlines of our original design as necessary until you’re sure we’ve designed a ring that perfectly captures the look you’re after.
