Purchasing a diamond is a big decision. Many people are hooked to the idea of owning a 1 carat diamond. However, many consumers want to know whether a 1 carat diamond is worth buying or if it’s more beneficial to opt for a 0.9 carat diamond.

Despite minor variations in size, the price difference is substantial which makes the 0.9 carat diamond an appealing alternative. Let’s explore why this might be the case and what you should consider when making your next diamond purchase.

Tips to Consider Before Buying a Diamond

There are 4 Cs of a Diamond that you should know before buying a diamond. They are as follows:

1st C is Color – A diamond’s color actually refers to its lack of color. Meaning, the more colorless a diamond is, the better its quality and higher its price.

Tip: Color distinction is subtle, and often visible only to a trained eye. Opt for Near Colorless Diamonds over Colorless, and you can save over 40%.

2nd C is Clarity – Clarity refers to how clear and blemish-free the diamond is. A flawless diamond has no visible inclusions and is rare to find. However, most diamonds have blemishes that can be seen under 10x magnifications.

Tip: The price of a diamond increases as its clarity moves from I to flawless. Go for slight inclusions – S-I1, S-I, which are not visible to the naked eye.

3rd C is Carat – The Carat of a diamond is its supposed size and weight. However, bigger is not always better. A 1 carat diamond may look bigger, but if it has an inferior cut, color, and clarity, it won’t look half as good as a diamond weighing 0.5 carat that has a high cut grade, color, and clarity.

Tip: Choose your size wisely, as every small change could mean a significant increase in price.

For example – A 0.90 Carat diamond is visually almost as big as a 1 Carat diamond but may be significantly cheaper.

4th C is Diamond’s Cut – Unlike popular belief, the cut is NOT the shape of the diamond. It refers to how well the diamond absorbs, refracts, and reflects light. In a layman’s language, the cut of the diamond is essential in determining its shine and brilliance.

Tip: When it comes to cut, it is recommended that you always go for the best.

0.9 Carat vs 1 Carat Diamond: Which One to Choose?

Psychologically, consumers are drawn to the 1 carat mark when buying a diamond, which creates a high demand for these diamonds and is slightly expensive in comparison to 0.9 carat diamonds. Whereas, the industry also promotes the value of 1-carat diamonds, and the price per carat rises at this level.

But due to a greater supply of 0.9 carat diamonds, they are more affordable and less expensive compared to 1 carat diamond.

According to gemologists, unless you compare a 0.9 carat diamond and a 1.0 carat diamond side by side, it is hard to notice the small size difference. A well-cut 1 carat diamond measures about 6.4-6.5 mm in diameter, while a 0.9 carat diamond is around 6.2-6.3 mm.

In terms of physical dimensions, the difference between them is only 0.2 mm. To see how small this difference is, simply use a ruler and look at the sub-divisions.

Diamond pricing is determined by a combination of factors, and carat weight is a key factor that affects costs.

Here’s a general estimate of how prices vary with changes in cent weight (1 carat = 100 cents).

Diamonds weighing 1 carat are in high demand and therefore price ranges from 15% to 25% or even more. This variation depends on factors such as diamond quality (cut, color, clarity), market conditions, and the specific retailer.

Therefore, compared to a 1 carat diamond, a 0.9 carat diamond would be more affordable for budget-conscious people.
