Kofsky & Stone is an independent jewellery brand run alongside my full-time career in technology. Because the business is driven by passion rather than needing to support a large retail operation, pricing can focus more closely on the true cost of materials and production.

Unlike many traditional jewellery businesses, Kofsky & Stone does not carry the same overheads associated with physical stores, large teams, or showrooms. This allows pieces made with high quality lab grown gemstones and precious metals to be offered at more accessible prices.

Each piece is produced by experienced jewellery manufacturers, and pricing covers the cost of materials, production, transaction fees, and tax. Most of the profit is reinvested into the business to support new designs and small-batch collections.

This approach allows the brand to focus on creating beautiful jewellery while offering pieces that represent excellent value without compromising on quality.

Our rings are available in sizes 5 through 10.5. If you require a size outside of those listed, please contact us via the form below and we will be happy to assist.

Ring Size Guide (Inner Diameter)

The inner diameter is the measurement taken across the inside of the ring from one inner edge to the other, passing directly through the centre of the ring. This measurement does not include the thickness of the band, only the open space where your finger sits.

How to Measure Your Ring Size

Option 1: Measure a Ring You Already Own (Most Accurate)

1. Place the ring on a ruler or measuring tape.
   
2. Measure straight across the inside of the ring, from one inner edge to the other.
   
3. Do not measure the outside of the band.
   
4. Match this measurement in millimetres to the chart above.
   

Option 2: Measure Your Finger Using String or Paper

1. Wrap a thin strip of paper or string around the base of your finger where the ring will sit.
   
2. The string should sit snug but comfortable. It should not be tight or digging into the skin.
   
3. Mark the point where the two ends meet.
   
4. Lay the string flat and measure the length in millimetres.
   

This measurement gives the circumference of your finger. You can then compare it to standard ring size charts or convert it to the closest ring size.

For the most accurate sizing, we recommend visiting a local jeweller for professional ring sizing.
