Every part, your choice.

Nothing at Newton's is made twice. Start with a ring, earrings, a necklace, a bracelet or a watch, change anything you like, then bring your design to Fifth and Main and we will make it with you.

This piece is being drawn. Your choices are saved and the preview will appear here.

Your browser could not open the 3D preview. Every option still works, and the design sheet lists them all.

Ring sizer

Find your size, three ways.

Read it off the chart, measure a ring you already wear, or wrap a strip of paper around your finger. The size you choose here goes straight into your ring design.

  • Measure at the end of the day, when fingers are largest, and not when they are cold.
  • Bands 6 mm and wider fit snugger. Go up a quarter size.
  • If your knuckle is larger, choose a size between the two so the ring slides on and stays put.
  • Not sure? We size every finger at the counter, and resizing later is done at our own bench.

Choosing the stone

The 4 C's, seen to scale.

Cut, color, clarity and carat weight describe every diamond. The grades you pick in the studio are the same ones we will show you in person, stone by stone, under the loupe.

How custom works

From your screen to your hand.

The studio is where the conversation starts. Nothing is ordered online; every piece is finished with you, in person.

  1. 01

    Design it here

    Change anything. If an option is missing, describe it in a note. The bench reads every one.

  2. 02

    Sit down with us

    Bring your design to Fifth and Main. We look at stones together and talk through every detail.

  3. 03

    See it before it is made

    We draw your piece to scale and walk you through it, so nothing is a surprise.

  4. 04

    Made for one hand

    Your piece is made once, for you, and never repeated.
