Antique ruby and mine cut diamond ring


This ring was made at the turn of the 20th Century and will look so beautiful on any finger, including making a wonderful engagement ring.

Made in 14 carat yellow gold, in the centre sits a beautiful oval natural ruby that measures 0.42 carats and displays such a wonderful bright red colour to it. This ruby looks so beautiful and is then highlighted by the two mine cut diamonds that compliment the ruby and ring perfectly. These diamonds total 0.52 carats and antique mine cut, or cushion cut diamonds as they are also known as, have become so popular in recent years.

Measuring 7mm wide at the centre, by 14.7mm across, this is such a beautiful ring that will always be admired.

What is a mine cut diamond? What is a cushion cut diamond?

At the start of the 18th century, a great leap forward emerged with the “invention” of the new 58-facetted diamond. At the time, these were the closest resemblance to today’s brilliant cut diamond. These are referred to as old mine cut diamonds, or “old miners” as well as “cushion cut diamonds” . These were cut often squarish or cushion shaped, with quite a steep angle on the crown and pavilion. This was to maximise weight retention in the diamond. As well as these features, 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.
