What you need to know about diamond shapes:
Although there are more than a dozen diamond shapes and cutting styles out there, some of them are industry locomotives, while others are rather a pick for clients with sophisticated taste.
Round: Absolute leader and number №1 customers pick in the world and UK in particular - especially when selecting a diamond for an engagement ring. Ideal symmetry, sparkling and classy these adjectives are the definition for rounds. 75% of all diamonds sold in the world have a round shape.
Princess: One of the top picks as well – in most cases, these diamonds are rectangular or square with pointed corners. Customers looking for stylish and modern looks usually go for the princess-cut diamond.
Emerald: Fashion-like shape diamonds can come with rectangular cuts or other square variations. This is the pick for customers who wish their ring to look super classy and elegant.
Asscher: Asscher cuts are a squarer version with clip-corners rather than elongated emerald diamonds. Asscher is the pick for clients who wish for their fabulous ring to have a unique look.
Marquise: French Royal Court style from as far as the 18th century. This diamond will perfectly fit an engagement ring with the maximum retro elegance and unique charisma.
Heart: A growing trend for young ladies with a maximum focus on romantic appearance. The best way to show true feelings is to go for a heart-cut diamond.
Pear: This cut provides the diamonds with extra sparkling angles, especially if the room is well-lit. Perfect for cocktail dress fit or if you want to conquer everyone at a white-tie event.
Oval: Ovals are often perfect for beautiful earrings due to their elongated shape. And no other shapes and cuts can match ovals in variations of multi-diamond pendants.
Radiant: The key feature of the radiant cut diamond is that it possesses the maximum number of facets – 70. No other shape can compete with a radiant diamond in this regard.
Cushion: Perfect pick for the people looking for “classic in retro elegance appearance.”

Basically, in the world diamond industry, diamonds are either “blood diamonds”, which means that the sources of the stones are associated with human rights abuses or violence. Or conflict-free diamonds indicate that the stones were mined in areas without war, violent abuses, or other strict labour forms.
Moon Ocean diamonds – are 100% conflict free. In addition, our customer service specialists will be happy to provide all detailed information about the origin of the diamonds we offer.
“Four C’s” of the Diamonds
The main 4 criteria stand for Carat, Cut, Clarity, and Color. When it comes to measuring the quality of the diamond – these four decide everything:
- 1. Carat weight is the size of the diamond itself. 200 milligrams equal to one carat.
- 2. Cut is the criteria which defines how well the diamond cut was. The main factors are height, angles and depth. Side factors are table, symmetry and polish.
- 3. Clarity is about inclusions and other blemishes in the stone. And the scale with six points (from included to flawless) is used to measure the clarity of the diamond
- 4. Color is measured on a scale from D to Z. where D is no hue and Z is yellow hued
All characteristics matter. That’s why the price dispersion of diamonds is so huge.
What’s the reasonable budget, or how much should I spend on a Diamond?
There is no simple answer to this question. Diamonds are about emotions. One question a man wants to avoid from her Lady is the one that may sound like, “Is this how you measure your love”?
