Who we are…


Karen Lindley F.G.A.A, J.A.A.’ – Gemmologist, Diamond Specialist, Master Jeweller in Sydney

Karen Lindley Sydney jewellery designer - master jeweller sydney
Karen’s strengths are knowing what works with what and ensuring a flow. Some people call it feng shui, she calls it meaning.

‘To me your piece of jewellery has to not only feel comfortable, look great and be reasonably priced – it has to pass my benchmark of excellence and look right to my trained eye. Over 40 years of experience as a gemmologist has taught me to trust my judgement and I am seldom wrong!’
