Details
Two millimeters is the sweet spot, and here it circles the finger without a break. Round brilliants nearly 2 mm across sit in shared prongs all 360 degrees, a full carat's worth of light with no clasp, no gap, no wrong way to wear it.
Larger stones mean bigger flashes of fire, and the shared-prong line keeps them locked shoulder to shoulder for an unbroken sweep. Choose lab-grown for the most carat for your budget or natural diamonds if you prefer, in 14K gold or platinum. Total weight sits around 1 carat and ticks up slightly on larger sizes.
It makes a generous anniversary gift and an even better everyday ring. Wear it as a wedding band, stack it with your engagement ring, or let it stand alone.
Total carat weight by finger size. A full eternity band holds more diamonds at larger sizes, so the total weight grows with the size you order.

Answers, before you ask
Your Questions
Can a full eternity band be sized?
Not without breaking the diamond line, so these are made to order in your size rather than resized afterward. Measure carefully or ask us for guidance.
Lab-grown or natural, what is the difference? Both are real diamonds. Lab-grown gives you more carat for the money; natural forms underground over ages. Select your preference under Diamond Type.
Is the carat weight exact? It is nominal, near 1 carat total, and scales slightly up on larger sizes. Think approximate rather than precise.
Does it work as a wedding band? Yes. At 2 mm it reads as a substantial wedding or anniversary band and stacks neatly with an engagement ring.
