Selecting a 1‑carat diamond ring—be it a stunning lab grown diamond ring or a rare natural diamond—is an exciting yet complicated process. An array of factors needs to be considered, from budgets to quality grading, ethics to styles before you say "yes." This expert guide will help you through every stage of the process, including the fundamentals of diamonds to the latest styles to complement your lifestyle, so you can walk away with a ring you will cherish forever.

Why 1 Carat?  Why is it so popular? 

 What is "1 carat" anyway? 

The carat of a diamond is a measure of its weight. 1 carat is equal to 200 mg (0.2 grams). A 1 carat weight class serves as a level of prestige: there is a presence and heft, but it still offers a feasible option for quality based on the other quality factors, Cut, Colour, and Clarity. 

Is size worth more than quality? 

A larger diamond isn’t always better. A poorly cut 1‑carat diamond may actually look smaller than a well-cut 0.90‑carat diamond. Therefore, it’s important to compare all 4Cs—Cut, Colour, Clarity, Carat—of a diamond.

Should You Go with Lab Grown or Mined for Your 1-Carat Diamond Ring? 

Your 1-Carat Diamond Ring 

Lab Grown Diamond Rings: Affordable and Ethical 

Lab grown diamond rings have skyrocketed in popularity, given their relatively smaller environmental footprint, ethical and sustainable sourcing, and budget-friendly pricing. A lab grown diamond is completely authentic and has the exact same physical and chemical origins as a natural diamond, often at least 30–40% lower in price! 

Pros of lab diamond rings: 

- Budget-conscious

- Sustainably created 

- Same brilliance and hardness as natural diamonds 

Cons: 

May have slightly lower resale value as compared to natural stones

Mined Diamonds: Conventional and Classic

Mined diamonds are created through billions of years of heat and pressure, below the Earth’s surface, and they bring with them a true history and a sense of rarity.

Pros:

- Generally considered to have greater resale and heirloom value

- Have a greater emotional or symbolic connections for some buyers

Cons:

- Greater price point

- Ethical and environmental concerns if the source is not known

Verdict: If ethics and budget are your priority then lab grown diamond rings are for you. If you are focusing on symbols, and resale, then natural is the way to go.

The 4 Cs of Diamonds: What’s Important with a 1-Carat Diamond?

1. Cut: The Maker of Sparkle

Of all the 4 Cs, cut is the most important  factors in a diamond’s brilliance and fire. A diamond that is cut poorly will not sparkle, no matter how beautiful the color or clarity.

Grades: Ideal, Excellent, Very Good, Good, Fair, Poor

Insider Tip: Make sure when you are shopping for a diamond that you prioritize cut, especially for 1-carat diamonds.  A 1-carat diamond should sparkle!  

2. Colour:  How White Of A Diamond Should You Get?

When it comes to diamond color, colors are graded D (colourless) through Z (huge tint in colour: yellow or brown).  In general, for a 1-carat diamond, the majority of buyers feel G-H diamond colour offers the best combination of value for the price and almost colourless appearance.  

Lab diamonds have more colour consistency because of the controlled process in which they are grown.

3. Clarity: How Relevant Are Flaws?

Clarity evaluates the presence of internal (inclusions) or external (blemishes) flaws. The clarity grading scale begins with Flawless (FL) and ends with Included (I1, I2, I3).

For 1-carat diamonds the best clarity range is as follows:

VS1–VS2: Very slight inclusions, usually invisible to the naked eye

SI1–SI2: Slight inclusions, visible under 10x magnification

You want to avoid overpaying for clarity grades that don’t provide any enhancements to visible beauty.

4. Carat: Size Versus Perception

Carat measures weight, not size, however typically, 1-carat round diamonds measure between 6.4-6.5 mm in diameter. Some shapes wear weight differently, which is to say a 1-carat oval or pear shape may appear larger.

Pro tip: A stone that weighs between 0.90–0.99 may provide a similar perceived size, but will save you more than enough to pay for lunch.

Which Diamond Shape is Most Impressive in a 1-Carat Size?

The shape of a diamond largely affects how that 1-carat diamond ring appears on the hand.

The Most Popular Shapes for 1-Carat Diamonds Rings:

- Round Brilliant: The most sparkle and timeless

- Oval: An elongated diamond that will elongate the finger and look larger than round

- Cushion: Vintage feel, great fire and brilliance

- Princess: Bold and modern with clean angles

- Pear: Unique and elongating and popular in modern rings.

The main takeaway is that elongated shapes such as the oval or pear will magnify how large the diamond appears compared to the round or square shapes.

What Ring Settings are Ideal for a 1 Carat Diamond?

The type of setting can affect the safety of your diamond, as well as how large or sparkly it appears.

Best Setting Styles for 1 Carat Rings:

- Solitaire: The original classic style that displays the diamond most prominently.

- Halo: Surrounding the middle stone with smaller diamonds/drops more than doubles the size and shine.

- Pavé: Adding diamonds beside the main stone along the band adds extra sparkle without taking away from the main stone.

- Bezel: The stone has a metal rim around it, which protects the stone. It is stylish and modern.

- Three stone: Two of the same sizes on either side of the middle stone creates presence and increases the symbolism.

New trend: Many of the lab grown diamond rings are being made with artistic asymmetric looks, with or without a minimal bezel. Clean and modern.
