The philosophy

More Diamond.
Less Markup.

A traditional ring passes through a dealer, a wholesaler and a showroom, each adding a margin before it ever reaches a hand. We buy stones directly and hold no retail floor.

The saving isn't a discount — it's the absence of three markups. Which is why a four carat centre stone here costs what a one carat costs on a mall counter.

See it on a hand first

Carat is weight, not size. Slide through two to eight carats and switch shapes to see how spread — the part people actually notice — changes.

Quality review

The Echols Standard

Five checks between the rough stone and your hand. Nothing ships until it passes all five — and until you have seen the footage.

  1. 01

    Stone selection

    Every centre stone is hand-picked from certified rough — D–G colour, VS2 or better, Ideal or Excellent cut.

  2. 02

    Independent certification

    IGI or GIA grades the stone before it enters our workshop. The report ships with the ring.

  3. 03

    Setting under 10x

    Prongs, pavé and halos are inspected under loupe magnification for seat, symmetry and security.

  4. 04

    Light review

    Photographed and filmed in daylight and studio light. We walk you through the footage before it ships.

  5. 05

    Final measure

    Weight, dimensions and finger size verified against your order, then hand-finished and boxed.

A cord of three strands

“Two are better than one, because they have a good return for their labor: If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up. Also, if two lie down together, they will keep warm. But how can one keep warm alone? Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken.”

Ecclesiastes 4:9–12

Every ring we make marks a covenant between two people and the God who holds them together. We pray over each commission before it leaves our bench in Atlanta.
