The Diamonds by Design experience

– Karen Lindley, Custom Jewellery Design in Sydney

A piece of jewellery can be worn for a lifetime and then passed onto loved ones. At Diamonds by Design, we keep this at the forefront of all our designs and ensure that each piece of jewellery is of superior quality. When you go to a jeweller who cares about quality and integrity, you can be assured you’re getting a one-of-a-kind piece.

Unlike jewellery stores that offer stock-standard designs, Diamonds by Design have specialised in custom jewellery for almost forty years. It’s our passion, and it’s what we do best.

When you step into the Diamonds by Design showroom, you can expect exemplary, personal service. We value all our customers and understand each custom jewellery piece is a reflection of your uniqueness and individual style.

About Karen Lindley

Jewellery Designer in Sydney, Owner at Diamonds by Design

With 40 years experience as a gemmologist, she has made engagement rings and custom jewellery for thousands of people. She is amongst the most well-known jewellers in Sydney, and for good reason – She has a great eye for detail, and works with each customer to ensure their piece of jewellery is something they’ll cherish for a lifetime.

There is not much Karen hasn’t seen when it comes to jewellery design. She is more than happy to assist if you have some ideas for a jewellery piece but need help bring them to life.

The Diamonds by Design difference

At Diamonds by Design, we consider our social and environmental impact. We strive to verify the source of all gemstones purchased and do not purchase stones that have origins we are not comfortable with. We promote customers to recycle or restore old jewellery pieces and aim to leave a minimal footprint on the planet. Karen also contributes to several charities.

Another point of difference is like yesterday …… a second generation customer came in with his late mother’s jewellery and i was able to go into my files and pull up the original purchase documents and work sheets from 1982!
