1 Carat Diamond Cost Described
The cost basis for any diamond depends on its origin (natural versus lab grown) its shape, and its combination of the 4Cs.
4Cs alert: Shopping online can make one falsely believe that the 4Cs are commoditized. A casual shopper wonders “how much is a 1 carat diamond ring?” goes to our search engine, sees a half-dozen 1.00 carat G color VS2 clarity excellent cuts and presumes they are identical. They are not, and that will typically be reflected in the price.
Remember that diamonds are like snowflakes. We classify them according to the 4Cs but there are variables within each of those Cs which create price differences. For example, color occurs on a sliding scale. Clarity characteristics within the same clarity grade have different implications. Differences in cut quality, within the same grade, can create price differences of up to 25% between diamonds which seem to have identical Cs in an online search.
Diamond Cost – Let’s Get Practical
What is the average 1 carat diamond price?
The answer requires context. There are 1 carat diamonds which cost only $1,000 in low grade commercial outlets (which we do not recommend). Alternately, a collection quality 1 carat diamond’s price may be as much as $28,000 in the luxury jewelry boutiques on 5th Avenue, New York City.
On PriceScope we trim out the low grade and 5th avenue prices. Among PriceScope’s vetted vendors the average 1 carat diamond price for a 1.00 K color SI2 clarity princess cut is $2500*, while the average 1 carat diamond price for an all bells and whistles 1.00 D color VVS1 super ideal round brilliant is $14,000.*

Remember the Cost Variables
Carat Weight: Be sure that the 1 carat diamond you’re considering has correct size appearance, in terms of its visual spread caused by edge to edge brightness (cut quality) as well as its physical spread.
Learn more specifics about 1 carat diamond size appearance on this page: 1 carat diamond ring.
Color and Clarity: Details not reflected on a grading report can impact 1 carat diamond prices. If two diamonds with identical Cs are offered at different prices by the same seller be sure to ask why.
Cut: A diamond’s price can vary up to 25% or more, depending on details of cut quality which are not listed on a grading report. There are far more average cut diamonds – at all carat weights – which have less physical spread than they should due to deep cutting angles and look visually smaller than they should in normal lighting because they are not cut with angles which promote edge to edge brightness.
Real World Information
True or false: Jewelers mark up diamonds by huge percentages and make enormous profit?
It used to be true. It’s still true in commercial outlets with low price points. When you buy mass produced department store jewelry nearly half of what you pay can be profit for the store.
Loose Diamond Values
The loose diamond game is completely different today. Jewelers used to mark loose diamonds up by as much as 100%. That still happens in many chain stores. The markups are even greater in the luxury boutiques on 5th Avenue in New York, but clients in those stores are often paying for the prestige of association with the store’s name, as much as for the product.
Retail Diamond Prices
Retail pricing has become extremely variable, depending on the sales channel. A 1 carat diamond purchased from a jewelry boutique in Ceasar’s Palace, Las Vegas, will be marked up considerably more than the same 1 carat diamond priced for sale by one of PriceScope’s vetted vendors, who use the industry’s most friendly markups.
The internet changed the way diamonds are priced. Even local jewelry stores have reduced the markups on loose diamonds. Today’s online sellers operate on extremely thin margins. They also tend to back their sales with no-risk policies.
Unlike retail prices, wholesale prices within specific classes and categories of natural diamonds are relatively consistent across the industry. This means, when asking “how much does a 1 carat diamond cost?” you can make apples to apples comparisons between diamonds offered by the same seller.
This brings us back the 4Cs alert above. If a seller is charging more for diamond A then diamond B, yet A and B have identical 4Cs, the gemologists who priced them judge diamond A to have greater value. If you’re curious about why, pick up the phone and ask.
