Another of the pen models from ST Dupont is the Ellipsis and for this one a short digression into the vagaries of common languages. In English Ellipsis usually refers to the literary convention for omitted material, often the three consecutive periods. In this case though it is the feminine plural of ellipse.
The Ellipsis design followed the earlier ST Dupont Classique, Gatsby, Lady and Montparnasse products that had been their very successful entry into the luxury fountain pen world. Those designs had been fairly straight forward cylinders produced from the finest materials to the highest standards possible.
For the Ellipsis they chose mirrored sections of an ellipse, still very simple and attractive lines, understated form.
In this picture, the Classique and Gatsby models are on the far right while the Ellipsis are the two leftmost pens.

The two pens are very similar in appearance yet quite different in feel and personality.
The gold toned pen is a pale gold plate over a brass body. It is a heavy pen yet very balanced and comfortable to use for extended periods.

With the introduction of the Ellipsis ST Dupont adopted the international standard sized cartridge converter system and so they increased the availability and choices when it came to what brand of ink the owner could use.
The nib is solid 18K gold that has been plated with Rhodium or Palladium (not sure which) to give a two toned effect. It is deeply engraved and also wraps around the feed.

The black Ellipsis has a resin body. It is much lighter than the gold one yet an almost identical balance when you are writing with the cap posted.

It has the same wonderfully smooth and responsive two tone solid 18K gold nib.

The caps are classic ST Dupont, they slide on and self center while the last 1/4" of travel is smooth and ends with that solid and satisfying "click" found in all of the ST Dupont pens except the Montparnasse.
The pocket clip is another wonder. It is a two part clip with a spring underneath that makes the pen easy to place in your pocket regardless of how thin or thick the fabric might be. It is yet another example of ST Dupont's attention to detail at even the most mundane level.
