About Us

I. Schlanger & Son Pty Ltd are leading jewellery specialists in Sydney

We specialise in high quality diamonds and our passion shines in our continuous drive to cut out the middleman in order to keep our prices low. We believe everybody deserves diamonds at affordable prices so we travel overseas to source the diamonds ourselves.

We are very meticulous in our choice of diamonds, as we want to deliver only the best to our clients. All of our jewellery is Australian made and manufactured by our company. First established in 1959, our family business has enjoyed growing success as we are well known for our original and unique, handmade designs.

Call I. Schlanger & Son Pty Ltd today; we are a cut above the rest.

Member of Gemmological Association of Australia and National Council of Jewellery Valuers
