Choosing a 4.5mm band
Band width changes how a ring looks and feels. Bands under 2.5mm are delicate and stack well with engagement rings, 3 to 4mm is a balanced everyday width, and 5mm and above gives a bold, substantial look that is popular for men's wedding bands.
How to choose
Start with the look you love, then pick the metal that matches your style and the diamond size that fits your budget. Prices in this collection range from $886 to $1,631, with shapes including cushion and round.
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.
