Art Deco ruby and diamond double row diamond cluster ring


Here is a ring from the gorgeous Art Deco era of the 1920's that exemplifies just why jewellery from this era has never gone out of fashion or style, and is just as popular today as when they were made .

This ring was entirely hand made in platinum in the 1920's and is so beautiful and unique for a few reasons.

To begin with sitting proudly in the centre is a gorgeous natural ruby that measures 0.60 carats and looks even more beautiful set into the pure white of the platinum.

And then there is not one, but two rows of diamonds, and making it even more exciting, they are a combination of having thirty larger single cut diamonds and eleven smaller rose cut diamonds. These diamonds come together to total 0.33 carats and add the right amount of sparkle that highlights this stunning double row of diamonds. And looking closely, it is not just a matter of two rows of diamonds, but the setting that the diamonds are set into, not only adds to the charm of the ring, but shows just how much time and attention to detail that went into hand making this ring all those years ago.

Measuring 14mm in diameter, this ring is certainly stunning and will no doubt be cherished and loved.

Art Deco ruby ring from the 1920's.

This Art Deco ruby and diamond double row diamond cluster ring is set with both rose cut diamonds and single cut diamonds.


What are rose cut diamonds?

Like the name implies, the rose cut diamond resembles a rose bud, comprising of a flat base with a number of triangular facets arranged in rows above each other, meeting at a sharp point in the centre.

First manufactured in India at the end of the 15th Century, this cut was perfected at the diamond cutting workshops in Antwerp and Amsterdam, and was very popular during most of the 16th and 17thcenturies.


Example of the rose cut diamond from the side and the top.

Because the base of the diamond was flat, stones were often foiled back to improve the brilliance of the stone. This was achieved by applying foils or tints to the base of the stone.

For a number of years, diamond cutters experimented with variations of the rose cut, resulting in some truly amazing cuts, such as the Dutch rose, half-Dutch and the boat- shaped rose.

What are single cut diamonds?

These are small diamonds usually around 0.01 carats to 0.05 carats and are often found on the shoulders of rings or surrounding a centre stone. While today modern technology will allow for a 0.01 carat diamond to have 58 facets and be a round brilliant cut diamond, single cut diamonds were used from the later part of the 19th Century up until around the 1930’s-1940’s. Commonly found with eight facets on the top (the crown) and eight facets on the bottom (the pavilion) these are sometimes found with total facets between 16 to 18.
