Technology Revolutionising Jewellery Manufacture

October 22nd, 2018

10 years ago, I wrote about handmade engagement rings. Back then, in times some may say were simpler, jewellers could merely listen to what the client wanted, or prepare a hand drawn sketch before manufacturing a piece of jewellery. During the handmade manufacturing process, seemingly minor details of the design may have been overlooked – attributed to “jewellers discretion”. When finished, the client was presented with the piece of jewellery. Whilst most of the time the client loved the finished product, sometimes the whole piece needed to be remade due to a minor detail. However, as with a lot of things in life, technology is changing how business is done and how products are manufactured and bought. Gone are the days of hand drawn sketches and handmade jewellery. Nowadays, CAD/CAM is what fine jewellery consumers are demanding.

White Gold vs Platinum – What Jewellers Wont Tell You

June 6th, 2013

Last week I received brochures from both The Platinum Guild and World Gold Council, espousing the benefits of their respective metals. However, during the purchasing process many consumers take advice from a jewellery sales person and end up bereft of any useful facts on the subject.

The Death of Australian Diamond Grading Laboratories

May 13th, 2013

The early to mid-2000s proved to be the heyday for Australian diamond grading laboratories. At its peak, there were five major labs – ADGL, Auscert, Bauer Gem Labs, DCLA and GSL. Diamonds certified by these five labs dominated the Australian diamond industry – from chain stores to high end retailers. Nowadays, the popularity of these certificates have dramatically declined, at least one of the aforementioned labs has closed and no new labs have opened, including the much hyped, or some say maligned, EGL Australia.

What I’ve Known for A Long Time But Meanwhile, Poor Hadassin Get Stuck in the Mud

May 24th, 2012

Last week, a furore erupted in the Australian jewellery industry over The JAA promoting Rapnet. Essentially, this promotion of Rapnet (which is a website which allows buyers and sellers from all around the world to trade diamonds) was seen by many as a way of bypassing local diamond wholesalers and giving business to diamond vendors overseas – certainly not what the JAA should want to promote?!

Why Jewellery Valuations Are Worthless

January 26th, 2011

A recent editorial in Jeweller Magazine calls for the banning of jewellery valuations on new jewellery, arguing that a piece of jewellery bought for $700 one day can then be mysteriously valued at $4000 the next day. The article then goes on to say that jewellery is the only everyday consumer product that valuations exist for, since TVs or furniture don’t have valuations.

December 2nd, 2010

Just like mobile phones have evolved over the past three decades, diamond cut grading has as well. Over the years, we’ve gone from assigning a cut grade by measuring a diamond’s table and depth to using advanced ray-tracing techniques to assign cut grades.
