Oval Diamonds


What is an Oval Diamond?

Oval diamonds have similar facets to a round brilliant cut diamond, but in an elongated cut. Although the first oval diamond is said to date from the 1300s, the modern oval cut as we know it was designed in the 1960s. Since then, oval-shaped diamonds have quickly become one of the most popular fancy cuts. Like a round diamond, an oval diamond is a brilliant cut. Its facets are designed to maximise light and scintillation.

What Makes an Oval Diamond Special?

Brilliant facets make oval diamonds wow with sparkle and fire, but the secret of oval’s popularity is in the shape. An oval cut’s elongated shape gives a larger ‘spread’ for the carat weight, meaning an oval diamond will appear larger than a round of the same carat weight. The elegant shape is also flattering to wear, helping to elongate the fingers.

How do you Know if an Oval Diamond is Well Cut?

First, we consider the visual impact of the stone - how does the fire, brightness, and scintillation appear? Second, the design - how well proportioned is the diamond? Finally, we look at the craftsmanship - how skillfully has the diamond been cut and polished? While ovals are not given a cut grading, there are some suggested parameters for a well-cut stone, including;

Length to width ratio: The length to width ratio of a diamond measures how proportional it is. Diamonds which fall within these parameters will be most pleasing to the eye, with a more distinct and even shape. For an oval, an ideal length to width ratio is 1.35 to 1.45 - however there is flexibility for personal preference if you prefer a narrower or wider stone.

Table: The table is the largest, central facet of a stone. The table needs to be large enough to let lots of light into the diamond, but not so large that the upper facets don’t have room to sparkle. Look for an oval diamond with a table ratio between 54% – 65%

Depth: A diamond’s depth is the top-to-bottom measurement of a diamond, from its table to culet. The depth ratio compares this measurement with the overall width of the stone. The depth affects the visual balance of a diamond and its brilliance. If a stone is too shallow or deep the light will not refract properly, escaping through the base of the diamond instead of the top. Look for an oval diamond with a depth ratio between 58% – 68%.

Is an Oval Cut the Diamond for You?

If you’re taken by the incredible sparkle of a round brilliant cut but would love something a little different, an oval cut diamond may be the answer. The graceful curves of an oval look beautiful on anyone, particularly if you’d love a stone that visually elongates the finger. An elegant choice, the oval cut suits a sleek solitaire or luxurious diamond-set engagement ring. Choose a minimalist mount to create a modern look, or enhance the brilliance with a halo. Thanks to their elongated cut, ovals are fabulous for getting maximum “show” for your money, appearing visually larger than a round stone of the same carat weight.
