Size Guide

Use this guide to determine the best size for your KeiStone piece.


  • 16 inches is the typical length of a women's choker and will not fit most males.
  • 18 inches in the standard for women and would fit like a choker necklace on men.
  • 20 inches is the standard for men's chains.


Chains that are too short can have an extender added to lengthen them. Please send a message if you need an extender added to lengthen the necklace you've ordered.



Small and large jewelers alike often provide ring sizing free of charge. KeiStone offers in-person ring sizing at popup market events. This simple process can also be done at home. You will only need a small rectangle of paper or a piece of thread, something to write with, and a ruler (*tip: you can also use the 'Measure" app on iPhone).

  1. Wrap a string or slip of paper around your finger.
  2. Mark where the material overlaps and remove.
  3. Using a ruler, measure the length of paper. 
  4. Corresponding sizes and measurements are as follows:

Currently, KeiStone pieces are handcrafted mainly in stainless steel and sterling silver. As opposed to gold and platinum, these metals allow us to control pricing without sacrificing quality.


Stainless Steel

Stainless steel is an alloy of steel and chromium. As someone whose ears get itchy even with sterling silver, Kei handcrafts most pieces using surgical grade steel which is a waterproof metal considered hypoallergenic due to it being free of copper and nickel. It is highly durable, tarnish resistant, and typically has a silver sheen, but, unlike silver, it will not corrode and is rigid, so it stands the test of time well. 

Sterling Silver

Sterling silver is a precious metal that is much softer than steel. However, the added metals make it stronger than gold which means it will hold up well to daily wear. Sterling silver is 92.5% pure silver and is considered hypoallergenic, though it may contain trace amounts of nickel (which could cause irritation in highly sensitive skin types).


Copper is the oldest metal found in nature that has been mined and prized since prehistoric times. The copper used in KeiStone designs is not alloyed (mixed with other metals) but is sealed with a coating to resist water and tarnish. This coating means that you won't get the green staining on your skin copper commonly causes (which is completelly harmless) until that coating wears off (usually around 3 months, depending on wear).


Brass is an alloy of copper and zinc which resembles the color of gold. Some elements of a few KeiStone pieces are acquired by disassembling and repurposing old brass jewelry. Due to it containing copper, this metal also leaves a green stain on skin. However, brass elements in KeiStone pieces are sealed with a tarnish and moisture resistant coating to protect it from getting a dark patina for a few months.
