10 Carat Diamond Rings: Your Guide to Quality, Pricing and More

There’s no question you have a 10 carat diamond ring. Unfortunately, it is impossible to miss its truly impressive size, and it sparkles with beauty. In other words — so long as you follow the 4C’s, and the diamond’s color, cut, clarity, and carat size, is excellent!


No doubt about this big diamond having an inherent eye catching matter. But, a diamond this large makes it so much easier for people to spot any flaws if you goof on your purchase of this critical diamond. 


So a 10 carat diamond — that's a 10 carat diamond, the largest diamond by itself on the ring. This isn’t 10 carat TCW (total carat weight) — meaning that 10 carat’s worth of diamonds are somewhere in the setting.

Choosing a 10 Carat Diamond

If searching for a 10 carat diamond, we recommend a budget to at least a few diamond shapes to look at. At this price most buyers begin with a minimum budget of $300,000 to about $500,000. The most popular post weights for a 10 carat diamond are Oval, Emerald and Pear Cut.

Cushion cut or radiant cut are also two other types of shape if you are planning for a rectangular shape. All diamonds of 10 carats or larger are unique in their being and the polish or exact dimensions of the cut may alter the overall brightness of the diamond. So we suggest that you compare a few diamonds before you buy.

Type I and Type II Diamonds

Type Ia diamonds with about 95% of diamonds contain trace amounts of nitrogen. Most engagement rings and other diamond jewelry are made from Type Ia diamonds. Intense canary yellow diamonds are commonly associated with Type Ib diamonds and that is why these diamonds are commonly used for jewelry. 

Type II diamonds are much less common than Type I diamonds, and Type II diamonds have fewer inclusions and greater clarity.

Diamonds without any measurable amount of nitrogen or boron impurities are called type IIa diamonds. These diamonds are often colorless, but some are seen in rare colors: pink, brown or blue. These are very rare, in fact they are less than 2% of all mined diamonds. Under high pressure and high temperature these diamonds are formed and can give the diamond a higher clarity and brilliance.

Cost of Diamond 

The famous 4Cs of diamond valuation—carat, cut, clarity, and color—make up the majority of the price of your 10 carat diamond ring and apply to all diamond rings. This diamond will certainly be an investment at 10 carats. 

Cost, quite obviously, the carat is fixed—we’re talking 10 carat diamonds! Cut, is an even more nebulous thing than carat weight, and will actually impact the price of 10-carat diamonds not as much as you think when similar cuts are compared. With that in mind we’ll search for it with the classic round diamonds.

A 10 carat diamond ring: How to get the best value

A typical price for a 10 carat diamond ring (which I assume you intend to buy) is, of course, a premium price. These diamonds are exceedingly rare, just as beautiful, and they cost what they’re worth.


However, some of the grades can save a lot of money if you give priority to a reputable retailer or shop. This means that you’re not going to pay a high price for a low quality diamond, or for grades that no one will notice by just looking.

Here’s what we recommend you look for when shopping for a 10 carat diamond ring:

  • Diamond cut: All this is unless you only buy a diamond with an Excellent (GIA) cut grade for round cut and ideal proportions for other shapes.

  • Diamond color: It also needs to be colorless, or more likely G-I in grade color, and be looked for in the proximity of colorless to the naked eye.

  • Diamond clarity: VS2 – VS1 in clarity, and check the diamond under the lens to be sure it has no obvious inclusions.

  • Diamond shape: pick which shape matches your personal style and your beloved. You'll have more choice round brilliant shapes, but an elongated shape like an oval or marquise diamond can make a diamond look larger and have a bigger face up area.

  • Vendor: For 10 carat diamonds, your best options are James Allen, Blue Nile, Abe Mor or Leibish & Co (for fancy coloured diamonds).

Go Lab-Grown

Lab made or “natural” or mined diamonds have no chemical or physical difference to each other. Yup, none at all! Depending on the one, what you have is mined from the earth or one is made in a lab.


The diamond certification number will even read too fast even for the most skilled jeweler to see what’s on it, which is if the diamond is lab grown or mined.


Since lab grown diamonds are not scarce, they are quite cheaper than the mined diamonds. They also tend to have lower occlusions and greater clarity—important for 10 carat gems.


By selecting a lab-grown diamond, you can score up to 80 percent off with a diamond as large as 10 carats.

Final Thoughts

A 10 carat diamond ring will attract attention wherever it goes. This diamond is so rare it will be many people’s whole lives before they have seen a jewel this rare and beautiful in person. Therefore; 10 carat diamonds are not cheap as the difference in price of low and high grades is often significant.

A diamond is mined and processed before it goes on the market. A rough diamond is marketed as ‘freshly’ extracted stone. It's crude to the industry. An extraction will be followed by evaluation of the clarity and color of a diamond. Additionally, it is necessary to take into account the cut a gem will possess. It tells you how much of a diamond’s body you will have to give up.

Processing also makes even big rough diamonds into smaller ones. One estimation for one body is that up to 60% of your body can go away. Nature gives clarity and color, so you can’t do anything. Although cut and carat are human made, it’s incredibly dangerous to shape a diamond into the exact shape a stone should be. There are ten general modern cut styles: 

  • Round; 

  • Cushion;

  • Oval; 

  • Asscher; 

  • Princess; 

  • Emerald; 

  • Pear; 

  • Marquise; 

  • Heart; 

  • Radiant.

An excellent cut will be far different than a very very good gut, which no commoner will be able to tell the difference between — these are different by microscope.

A very good cut

An excellent quality is slightly more expensive than the third best, and here’s why. You get so used to imperfections at this point, that in turn you notice at an edge where not so much care was taken to save the size. If you are searching for a budget stone it is a good option.

A fair cut

We are worse quality here. On the size, not the cut, the jeweler makes his effort. Budget decision, very, but not recommended to select so, it will damage the light reflection and brilliance.

A poor cut

At least the quality where we gave someone a size of diamond over a clean cut. Cut geometry is broken. It is quite beaten down and dull in reflection and brilliance. In terms of looking the best, you need a fabulous cut diamond of at least 2.5 carats. A diamond with this quality will be masked, by a sharper edge and a deeper angle of brilliance, by the possible blemishes on it.

1.5 Carat Diamond Rings: Your Guide to Quality, Pricing and More

Do you want a diamond for a special occasion, but aren’t entirely sure which carat weight to go with? The carat weight of a diamond is actually a key factor in how well a diamond sells. But many buyers prefer a 1.5 carat jeweled ring, which is big enough to impress, yet small enough to stay under budget. 


This weight feels so heavy, it presents such a stunning appearance of heft without the big price tag usually required for a larger diamond. The characteristics, pricing, and advantages of a 1.5 carat diamond, especially an engagement ring, are all detailed in this guide to help you decide if this is the right diamond for you.

What Is A 1.5 Carat Diamond?

For those who look for more than 1 carat, but want to keep within their budget, a 1.5 carat diamond ring is “bullseye.” This type of diamond is similar to 2 carat one: A difference of only 0.6 mm between their diameters in a round cut. Now, let’s compare 1 and 1.5 carat round cuts: The difference between now and then is almost a 1 mm. You can have a vision of a 2 carat-ish diamond engagement ring and double its price. 


A 2 carat natural diamond costs roughly twice as much as a 1.5 carat diamond, but the 2 carat diamond — seen from above — looks 10 percent bigger. The 1.5 ct diamond round cut is about 7.3mm, approximately face up size.

The exact measurements for any one 1.50ct diamond will depend on the diamond’s cut parameters. The shape and cut quality of a diamond may make it appear larger than any other, for instance elongated diamond shapes may be perceived to be larger than a round brilliant even if they are the same weight.


Additionally, an expertly cut diamond will return maximum light and spark, while a poorly cut diamond will produce a less brilliant, smaller visual live. Purchasing a 1.5 carat diamond allows the buyer to purchase close to the physical size of a 2ct diamond at a reduced premium for most buyers.

Why is a 1.5 Carat Diamond so Expensive?

1.5 carat diamonds can range from anywhere around $5,000 to over $30,000, and the price will be based on the careful consideration of several factors:


  • Clarity grading

  • Color grading

  • Cut quality

  • Diamond shape

  • Market influences

  • Jeweler pricings

Its a 5 Carat Diamond versus a 1 Carat Diamond

I’ve had to weigh up past relative differences between 1 and 1.5 carat diamonds in the past. Just because they’re bigger than the one you already have, doesn’t mean there can’t be a whole lot more difference too.

Price

In general, the larger the diamond, the more it will cost; yes in total that goes exponentially as it’s described; that means a 1.5 carats would be 1.5 times the diamond of 1 carats.

Size Differences

The size of a 1.5 carat diamond will be about 7.3mm wide, but will depend on the cut. An average diamond, roughly 1 carat, would be about 6.4mm in diameter. A 1 carat would be probably the best because this looks like a huge difference, but when you wear it on a ring finger, it’s pretty noticeable.

But the disadvantage of this is that you are going to end up with less diamonds in the form of resale value but you will get more if you opt for 1.5 carat diamonds.

Quality

The qualities of the diamond itself are inherently dependent on its diamond quality. They would sell their amazing 1 carat diamond and end up buying a terrible 1.5 or vice versa.

The Size of a 1.50 Carat Diamond

In the End

A 1.5 diamond ring is 5,000$ to 40,000$ per carat. Remembering that is about multiplying the wholesale price by 1.5 and adding the price of the ring itself. If you accept the 1.5 carats, this will be from 7,500$ up 60,000$ plus the ring. Worried about finding a perfect 1 ½ carat diamond engagement ring?
