All McCaul Goldsmiths’ jewellery is made from 18 carat yellow gold, white gold, rose gold or platinum. Our diamonds and gemstones are sourced from trusted suppliers in the UK and Europe and are conflict-free. If you see a design you like in our collection but would like it in a different combination of metal and gemstone we can make it to order and can also source diamonds and gemstones for you. Some of our designs are one-of-a-kind and are made with unique or unusual gemstones. Although we may not be able to repeat these, we can work with you to create a bespoke piece of jewellery based on the design. Visit our bespoke page to read more about the process.
