Cushion cut engagement rings – Why are they different than other diamond cuts?

A few facts about cushion cut engagement rings:

Cushion cut diamonds got their name since they resemble a stuffed pillow or a cushion. Back in the 18^th century people didn't have all the surrounding lights that gave diamonds the entire extra spark. 

Jewelers then, looked for a diamond cut which will “catch” candle lights in the widest spectrum, since that was the only light source at night. Engagement rings can come in several shapes such as a cushion, rectangle, square (princess), round or oval.

Cushion cut diamonds have 60 facets (the smooth and polished parts that make up a stone's surface) and a thick looking stone with rounded corners that makes them very attractive and really hard to ignore.

Modern day Cushion cut engagement rings

Thanks to certain improvements we had in diamond cutting technology; Modern cushion cut diamonds have
been modified to the kind of lights we are surrounded by these days. 

Since the facets on top of the diamond are fairly large, it is important to have a good quality diamond.

Another important step is to test the cushion cut engagement rings in more than one type of light.

Cushion cut diamond engagement rings are very popular worldwide and would be perfect for romantic couples who look for a vintage or antique engagement ring.

Bezel facet: On a round brilliant diamond, these are eight large kite-shaped facets on the crown.

Brilliance: The term used to describe the reflection of white light emitted from the diamond in its “face-up” position. This is the main characteristic that differentiates diamonds from other, less brilliant, gemstones. (No other gemstone has the power to equal the extent of a diamond’s light reflection).

Clarity Enhanced Diamonds - Good or Bad

Clarity enhanced diamonds are primarily a very good advance in the industry as it takes natural diamonds that have visible imperfections, which is not something that most people want in their diamond, an makes the diamond clearer and more sparkly. Consumers can enjoy real natural diamonds that look visibly flawless at a lower price without affecting the true value of the diamond. Most good jewelry manufacturers that offer clarity enhanced diamonds will offer a lifetime guarantee on the enhancement.

There are two types of clarity enhanced diamonds. The good treatment is a silicone based filling that can last a lifetime. The second, bad, type is a bromide based treatment that can fade and discolor over time. The trouble is being able to differentiate the good treatment from the bad.

As I mentioned in one of my older posts about CE diamonds, it is at the end of the day your choice, but it should be an educated one as there are serious advantages of purchasing a CE diamond, however it is important to know what and where to buy (just like everything else).

So...are clarity enhanced diamonds good or bad?

This is a checklist for you to make the right choice:
