Services
Over 40 years of experience as a gemmologist has taught me to trust my judgement and I am seldom wrong!' Three generations of Diamonds by Design have treated customers with care, honesty and professionalism and we still pride ourselves on old-fashioned personal service, catering for the individual needs of everyone interested in purchasing fine jewellery, diamonds and custom-made engagement rings in Sydney.
Whether you are looking for a wedding ring, a design for your engagement ring, a unique piece of diamond jewellery or a gem, Diamonds by Design can offer you a bespoke service. Diamonds by Design works with clients to determine exactly what they want, and then all the way to the ultimate piece.

To take the uncertainty out of a purchase, Diamonds by Design offers a pre-purchase advice service that will address any of the questions you might have before committing yourself financially.Parting with a large amount of money can be a daunting prospect, especially if you have been unable to see and touch the jewellery beforehand.
To have and to hold from this day forward, for better for worse, for richer for poorer, in sickness and in health, to love and to cherish, till death us do part, according to God's holy ordinance; and thereto I plight thee my troth. And as the evidence of permanent love, and proof that you are looking forward to a permanent future together, what about the engagement ring?
Diamonds by Design is based in the centre of Sydney, in the iconic Dymocks Building in George Street. And Diamonds by Design doesn't just specialize in diamonds, although we love them in every hue and shape. Because coloured diamonds are so rare, they are prized, and because they are so hard their high polish makes them appear more vivid than other gemstones.
Jewellery designers conceptualise, prototype and detail for manufacture items of jewellery such as rings, brooches, bracelets, necklaces, watches, eyewear and ear rings. They have specialised knowledge of the metals, jewels, precious stones and other materials associated with personal adornment. They may develop designs for mass or batch production or they may develop special items to satisfy one-off commissions.

I had to engrave a dog tag, and Karen was the only one in the Sydney area that quickly replied to my email and booked me an appointment for the next day. I really appreciate her help.. and the result was amazing! Highly recommend.

Karen helped my fiance to create the perfect engagement ring. Karen was such a pleasure to deal with through the sourcing and creation process, we of course went on to have her make our bands.
Karen is very reliable, honest and helpful and I would have no hesitation in recommending her for any custom diamond jewellery.

Thank you Karen, for my gorgeous custom made Eternity necklace! Friends of Diamonds by Design - My well meaning but design challenged husband bought me some lovely but mismatched birthstones for my children that I think I was to wear together on a necklace. However we were one birthstone short and then fell pregnant with another "surprise". In… despair, I packaged the whole lot up and sent them to Karen to try and work her magic! And work it she did! After securing details of all our family's birthstones, she set to work designing an absolutely gorgeous heirloom piece. All I had to do was
