How To Sell Diamonds Online at the Best Price

Have one or two diamond jewellery that you no longer need or want? You can sell them to earn a little extra cash!

But to sell diamonds and get the best price in return can be an intimidating process. You would need to have a clear understanding of the diamond reselling market to sell diamonds at the maximum profit. Most importantly, you would need to have a clear idea about the diamond jewellery you want to sell itself.

It is not hard to guess that the diamond-selling process can be quite tedious and time-consuming. But to make the process a tad bit easier and navigable for amateurs, we have prepared this end-to-end guide on how to sell diamonds online at the best price. Here, we will take you through the process one step at a time, and help you gain critical insights with expert knowledge.


Step 1: Get Your Diamonds Appraised

First & foremost, we highly recommend that you get your diamonds appraised if you want to sell them at a higher price. Non-appraised diamonds will most likely fetch you a lower price than it is actually valued. The reason is simple. Ask yourself: will you spend a fortune buying a pre-owned diamond jewellery that is not certified by the right authorities? The answer is probably no.

Getting appraisals will add credibility to your diamond jewellery and the buyer would know that it is authentic. But if you want to sell diamonds that are appraised, you will need to keep certain things in mind.

Find a qualified & professional appraiser. 

Getting your diamond jewellery appraised by a random organization will barely contribute to your effort. As such, having a professional appraisal is extremely essential, particularly if your diamond jewellery is potentially worth $2000 or more. Before you send it for appraisal, conduct your personal research about the appraisal association and make sure that they are certified.

Convey to the appraiser the reason for your appraisal request.

Diamond jewellery appraisals are done due to a variety of reasons, most commonly for getting it insured. The appraisal done for resale can differ from the one for insurance. Hence, letting your appraiser know that you plan to sell the diamond will help you get a better and more realistic idea about your diamond’s value in the resale market.

Have your diamond professionally evaluated by a gemological laboratory.

Most diamond specialists would recommend getting your diamond jewellery professional evaluated by well-known authentication authorities. These organisations, for example, the international gemological laboratories like the IGI (International Gemological Institute), GIA (Gemological Institute of America), or HRD (Hoge RaadVoor Diamant), can provide you with a more accurate & objective appraisal. They will deliver a full lab report with which the value of your diamond can be more correctly appraised. Moreover, a Diamond Grading Report from a leading gemological laboratory will validate the appraisal and certify its authenticity. You can produce the grading report during the time of selling to add authenticity to your item and justify the price you are asking.

Step 2: Educate Yourself About Diamonds

You cannot sell diamonds without contemplating their characteristics. The 4Cs, along with shape, fluorescence and rarity, form the most intrinsic characteristics of your diamond. Each of these elements can significantly influence the desirability of your piece, and hence its price. They will also influence the buying decision of the potential buyer.

So we suggest you get as much information as possible about your diamond. It will give you an upper hand and will help you negotiate your price with your buyers.

The 4Cs

The 4Cs are the holy grail of diamonds. These include the colour, cut, clarity, and carat weight of a diamond.


Many think that real diamonds are sparkly white or colourless. Although colourless diamonds are the most commonly available ones, there are coloured diamonds as well. These have different hues of colours like yellow, blue, pink, green, and even black. Coloured diamonds are more commonly referred to as fancy diamonds.

Standardised colour grades are used to determine diamond colours of both white and non-white diamonds. The GIA categorises diamond colour grades into 5 levels:

  • Colour grades D, E, and F refer to colourless diamonds
  • Colour grades G, H, I, and J refer to near-colourless diamonds
  • Colour grades K, L, and M refer to slightly yellow-tinted diamonds
  • Colour grades N, O, P, Q, and R refer to very pale-yellow diamonds
  • Colour grades S to Z refer to light yellow diamonds
  • Colours grades above Z refer to fancy-coloured diamonds

Fancy-coloured diamonds with higher intensity of colour grades are rarer, and hence are more valuable and expensive than white or hued diamonds. So if you sell diamonds that have colour grades above Z, they will fetch you a higher price.


The cut of a diamond is relative to its shape and cut quality. They create sparkles, emphasising the brilliance of the diamond. The brilliance, in turn, influences the value of the diamond. The cut, thus, forms an essential factor in determining your diamond’s price.

There are three common types of cuts:

  • Brilliant Cuts: Brilliant cut diamonds reflect more light and create a dazzling effect. The refined angular cuts and fantastic radiance enable the diamond to stand out, making the brilliant-cut diamonds generally more expensive.
  • Step Cuts: Diamonds with step cuts offer a shiny yet sober effect, allowing a more unique and elegant look.
  • Old World Cuts: Old-world cut diamonds possess a soft sparkle. They resemble a vintage look and exhibit sophistication, although much less dazzling than brilliant-cut diamonds.

The price of the diamond often depends on the cut grades. The GIA, for example, has three cut grades for diamonds.

  • Good Cut, for diamonds that sparkle.
  • Very Good Cut, for diamonds that reflect light better and sparkle more.
  • Excellent Cut, for the most brilliantly-cut diamonds which are the most expensive.


The level of clarity of an individual diamond characterizes the overall quality and price of the diamond. The clarity is essentially measured by the level of its inclusions, flaws, and internal crystal structures, and is defined by standardized clarity grades. To put it simply, a higher clarity grade means fewer imperfections and flaws in the diamond.

GIA has its diamond clarity scale defined by 11 specific grades across 6 categories, such as:

  • Flawless (FL): Diamonds graded FL have no inclusions and no blemishes visible under 10x magnification.
  • Internally Flawless (IF): Diamonds graded IF have no inclusions visible under 10x magnification.
  • Very, Very Slightly Included (VVS1 and VVS2): Diamonds graded VVS1 and VVS2 have extremely slight inclusions barely visible under 10x magnification.
  • Very Slightly Included (VS1 and VS2): Diamonds graded VS1 and VS2 possess minor inclusions visible under 10x magnification.
  • Slightly Included (SI1 and SI2): Diamonds graded SI1 and SI2 have noticeable inclusions under 10x magnification.
  • Included (I1, I2, and I3): Diamonds graded I1, I2, and I3 possess noticeable inclusions under 10x magnification and affect the transparency as well as the brilliance of the diamond.


The most commonly used price determinant of a diamond is its carat weight, which refers to the weight of the diamond. You definitely have referred to the carat while buying a diamond jewellery. As such, you would need the same while selling it.

An easy way to determine the carat weight of a diamond is its size. The bigger the diamond is, the higher its carat weight is. High carat weight, in turn, makes the diamond more expensive. Thus, a one carat diamond will be priced higher than a 0.90 carat diamond. So knowing about the carat weight of the diamond you want to sell will enable you to set a reasonable price on it. Informing your potential buyers about it will convince them better to pay your asking price at the same time.

Diamond Fluorescence

Taken together with the 4Cs, the fluorescence of a diamond plays a vital determining factor in its resale price. Fluorescence refers to the ability of certain diamonds to emit a multicolored glow under UV light exposure. A diamond possessing higher fluorescence will likely fetch a lower price than a diamond possessing lower fluorescence or none at all. For instance, a diamond colour graded E, with VS1 clarity and strong fluorescence will sell for 3-5% less than an E-coloured diamond with VS1 clarity and zero fluorescence.


Step 3: Determine Your Jewellery Setting

The diamond you want to sell most likely comes with a setting unless you are selling loose diamonds. The setting of your diamond jewellery will greatly impact the overall price of your piece. For example, if the diamond is set in gold, you will need to add up the price of the metal to your resale price. The same goes for platinum or silver settings. The price will only vary depending on the type and quality of the metal the diamond is set in. It’s even better if the piece of jewellery has other diamonds or stones set in it alongside a primary diamond. The setting, along with the design, level of sophistication, and other stones will help you set a high resale price.

Know your diamond’s history

Before you sell diamonds, learn as much as you can about your diamond’s history. For instance, where the jewellery and the diamond came from, when it was purchased, from which company was it purchased, the original price of the piece, and so on. If your diamond jewellery is a family heirloom, you can sell it as a vintage piece as well. Pitching your diamond as vintage will likely attract more buyers and fetch you a higher price.


Step 4: Set a Price

You can sell diamonds either by setting your own price or go with the price set by the buyer.

Determine the resale value of your diamond

First things first, figure out the fair market value or resale value of your diamond. Several factors can influence the resale value, such as the overall quality of the diamond, the setting, the condition of the jewellery while selling, the subjective appeal of the piece, and so on. Taking all these together, the desirability of the diamond jewellery you are selling will be determined. The more desirable it is, the more price it will fetch. However, expect the resale value of your diamond to be lower than its retail value.

Research selling & reselling trends

If you are setting the price yourself, or need an idea about the possible price your diamond jewellery can fetch, we suggest you figure out what a piece like yours generally fetches in the market. This will help you set more realistic expectations. You can go through similar pieces of diamond jewellery on resale sites; look for diamonds that have similar carat weight, colour grade, clarity, cut, setting type, setting material, certifications, purchase history, etc. Now keep note of the price range in which similar pieces are being sold. This will offer you first-hand knowledge about the market and buyer trends, and you will better understand the real worth of your piece in the market.

Sell your diamond at the appraised value

If you have no idea about what your diamond jewellery might fetch in the market, you can always trust the appraisal. The appraised value of a diamond is determined based on professional estimates, taking all its characteristics into consideration. As such, selling your diamond jewellery at the appraised value ensures that you are getting the best price.
