Oval Cut Diamonds

0

Oval Cut Diamonds are not dissimilar to Round Brilliant Cut Diamonds and the brilliance they often display is very nearly equal to that of a Round Brilliant Cut. The other major positive with an Oval Cut stone is that the shape can be used to effectively accentuate longer, slender fingers.

As with all Diamonds one factor of major importance is what you, the customer wants or expects from their Diamond. What is right for one (or even the masses) may not be right for you as an individual.

Any Diamond Broker / Dealer / Retailer / eTailer worthy of your attention should offer you a reasonable time-scale with which you have the Diamond to decide whether you like it & to have it checked out independently by someone else as well if you so wish. (The usually accepted time period tends to fall anywhere between 15 and 30 days, giving you plenty of time to decide whether or not you have found the right Diamond for you).

Having said all of the above, here comes the usual length to width ratios:

Acceptable is anywhere from 1.5-1.75:1, whereas the most desirable is said to be 1.5:1.


Marquise Cut Diamonds

The shape of Marquise Cut Diamonds is a shape that is designed to maximize the Carat weight of a given stone. If not set with other Marquise Cut Diamonds, then Round Brilliant or Pear are the shapes / cuts that complement the Marquise the most effectively. The Marquise is an excellent choice for people wanting to make their fingers appear longer and more slender.

Acceptable length to width ratios are generally from 1.75-2.25:1, whereas those of you seeking the closest to perfect you can get should consider the length to width ratio of 2:1, universally considered to be the most aesthetically pleasing.

Heart Cut Diamonds

The main advantage of a Heart Shaped Diamond is that it has a pavilion that is nearly round. This results in real beautiful brilliance. When choosing a Heart Shaped diamond do bear in mind and pay special attention to the Color you select - any grade above an I Color may well equal visible Color in the corners of your otherwise beautiful stone.

Don't be too quick to let this put you off though - remember certain inclusions, or even patches of visible Color may well be hidden by your setting if you choose this wisely. If in doubt - Ask!

Emerald Cut Diamonds

The main factor differentiating an Emerald Cut Diamond from other Cut styles is the pavilion which is generally cut with rectangular facets, designed to create a unique brilliance.

The down-side with the Emerald Cut is the fact that this particular shape serves to exaggerate the Clarity of a Diamond and does so even so much as to determine that if you were to choose an Emerald Cut Diamond with an SI1 Clarity (normally an eye-clean Clarity) you would need to take care and pay particular attention to the Diamond Certificate's plot and where what inclusions were contained.

With this shape you should really take professional advice before purchasing and adopt a look before you leap mentality so as to ensure that you get the right stone for you.

With regards to length to width ratios, acceptable ratios are widely considered to be 1.55-1.75:1, with a beautiful and very desirable shape likely to have a length to width ratio of somewhere between 1.30-1.40.


Cushion Cut Diamonds

Believe it or not, one of the main the reasons that Cushion Cut Diamonds have larger than average facets and rounded corners is to maximize their brilliance under candlelight!

Whilst I am the first to ask why, the answer is actually very simple......Cushion Cut Diamonds enjoyed excellent popularity around 100 years ago, before the event of electricity.

One very important factor to consider if you choose to buy a Cushion Cut Diamond is
Clarity as the larger than average facets tend to accentuate any inclusions that are present.

It is generally accepted that good-looking length to width ratios fall between 1:1 & 1:2.
