radiant shaped lab grown diamond ring

RADIANT SHAPE

If the corners on the princess cut seem too hard-edged and geometric (for lack of a better word), consider instead the radiant diamond shape. With beveled corners and 70 facets, this breathtaking option provides an absolutely brilliant sparkle. When viewed from above, the radiant cut’s higher crown and smaller table also gives it a circular pattern. You can think of the radiant shape as something of a missing link between square and round diamond shapes.


Radiant diamonds’ unique shape gives it the appearance of being larger than it actually is, while its beveled corners make it more durable than the princess cut — perfect for those who live active lifestyles.

asscher lab grown diamond ring

ASSCHER SHAPE

Asscher diamonds are an interesting study in diamond-shape popularity. First pioneered in 1902 (and named after the Asscher brothers of the Asscher Diamond Company), Asscher diamonds didn’t actually become a popular choice until the 1920s, where their uniquely Art-Deco shape perfectly fit the style of the time. Of course, once Art Deco became passé, the Asscher cut went out of vogue right along with it.


But the Asscher is making a comeback, and by improving upon the original design, gem cutters have introduced a new-and-improved Asscher with 74 facets and greatly increased brilliance.


If you love the Art-Deco look, want something undeniably brilliant, and are after a unique diamond shape that you’re not likely to see riding on the average person’s finger, then consider an Asscher diamond.

heart shaped lab grown diamond ring

HEART SHAPE

A heart shaped diamond is just that: heart shaped! More specifically, a heart shaped diamond is essentially a pear diamond with a rounded cleft at the top, creating two “lobes.” In terms of diamond shape, heart diamonds are often considered the most romantic option (for obvious reasons). Heart diamonds are also thought of as being more feminine than some of the other shapes.


Interestingly enough, heart diamonds are also much less common than most other diamond shapes, so if you want something capable of standing out in a crowd, then the heart shape may be right for you.

Summary

Now that you have a basic idea of the most popular diamond shapes, you should now be more prepared to go in and look at diamonds for your jewelry collection. To help you further, here are some common questions that you might have:


Which diamond cut sparkles the most? Technically the round brilliant diamond cut should sparkle the most, but it mostly depends on the quality of the cut itself. If you work with us at Clean Origin, we will make sure you get a radiant diamond cut that most speaks to your heart.


Which diamond cut looks the largest? This is also something that depends on the size of your diamond, but as stated above, emerald, pear, and oval cut diamonds can give the illusion of a greater size diamond. Again, work with one of our Clean Origin representatives, and we will make sure that you get the perfect size diamond for your style.
