Diamond engagement ring in platinum and our own 16 carat gold

It is one thing to design a ring on a computer with the help of a CAD program and have a ring cast in gold, it is another to have a ring that has been entirely made by hand in not only an antique style, but also using techniques used years ago as well as being made in a very unique colour and carat of gold.

Made in platinum at the top, the rest is made in our own 16 carat gold. The story of how we came about our own 16 carat gold is published here and well worth a read: https://www.kalmarantiques.com.au/articles/our-own-16-carat-rose-gold/  The colour of this 16 carat gold has such a wonderful warm tone to it that looks amazing on the skin and combine this with genuine antique diamonds set into the ring in a handmade setting, and you have a diamond engagement ring like no other.

Sitting proud in the centre is a gorgeous antique mine cut diamond which measures 0.51 carats and is H in colour and Si in clarity, meaning that it faces up lovely and white and has no inclusions that you can see with the naked eye. The mine cut diamond was first cut in the early 1700's and has become so popular in recent years that modern diamond workshops in Antwerp and India have started to cut diamonds once again in this cut, however nothing beats a genuine antique diamond.

Then set on each side are three single cut diamonds that have been set in such a beautiful setting with a millgrain finish. The attention to detail is just wonderful and makes this ring so exciting to look at from every angle.

An engagement ring should be as unique as you and not one that is a mass produced clone, and this engagement ring is as unique and special as you.

Diamond engagement ring in platinum and our own 16 carat gold

This diamond engagement ring has been entirely handmade by our Master Jeweller in platinum and our very own 16 carat gold. This is a gold carat and alloy that we make ourselves and is exclusive to our workshop and designs.

In the centre of this engagement ring is a mine cut diamond measuring 0.51 carats.

The mine cut diamond was first developed at the start of the 1700’s.

This cut is the closest resemblance to today’s brilliant cut, and are referred to as old mine cuts, or old miners. These were cut often squarish or cushion shaped, with quite a steep angle on the crown and pavilion, to maximise weight retention. As well as this, the “old miners” often had quite a large culet or “collet”, the horizontal base formed by the blunting of a point when the stone is cut as a brilliant.
