Why round is still the favorite
More than half of all engagement rings sold carry a round brilliant, and for good reason. Its 57 or 58 facets are arranged to bend light back up through the top, so a well-cut round shows more white sparkle and colored fire than any other shape. It also hides small inclusions and a hint of warmth better than step cuts, which means you can choose F color and VS2 clarity and still get a stone that looks bright and clean.
Settings that suit a round diamond
A round works in almost every design. A four-prong solitaire shows the most diamond; six prongs add security and a softer outline. Hidden halos add sparkle from the side without changing the top view, while a full halo makes a 1.5 carat center read closer to 2 carats. If you plan to wear a wedding band flush against your ring, choose a low-set head or a straight band.

How to choose

Are lab grown diamonds real?
Yes. Lab grown diamonds are made of pure carbon with the same crystal structure, hardness and sparkle as mined diamonds, and they are graded on the same color, clarity and carat scales. They typically cost 70 to 90 percent less and have a traceable, conflict-free origin.
Sizing, care and custom requests
Every piece is made to order, so you can choose your ring size, metal and, on many designs, the diamond size and quality. Clean your jewelry with warm water, mild soap and a soft brush, and store it separately to avoid scratches. Want a change to a design? Contact our team for a custom quote.
