How Much Is a Diamond worth?
How much a diamond is worth depends on a variety of factors, including its cut, clarity, colour and weight (carat). A diamond’s value will also depend on its condition, as and if the owner has any of its original certificates. The average selling price for a diamond in the UK ranges from around £1,200, up to hundreds of thousands of pounds.
When you buy or sell a diamond engagement ring, diamond earrings, or other diamond jewellery, the price of the diamond will depend on a variety of factors. This is good news for people that are looking to buy diamonds while on a budget.
How to Value a Diamond
It’s important to understand how to value a diamond before selling one. That’s because you to make sure you’re getting a fair price for your pre-owned jewellery pieces.
Often pawnshops and auctions will take a cut of the sale for profit-meaning you don’t necessarily receive the actual worth of your diamond. But with a trusted and reputable diamond wholesaler like YL Diamonds, you can be confident to receive the true worth when valuing your diamonds. Our diamond valuation process is completely transparent, so you can rest assured you’re receiving a fair price when selling your diamond.
Valuing a Diamond Using the 4 C’s
The “4 Cs” are a set of criteria that diamond wholesalers and retailers often use to estimate a diamond’s worth. Originally a guideline established by the Gemological Institute of America (GIA), the 4 C’s are as follows:
1. Carat
The “carat” refers to the diamond’s weight. 1 carat equals 200 milligrams (0.007055 ounces). The higher the carat, the more the diamond is likely to be worth.
2. Colour
Diamonds come in all shapes, sizes and colours. The most popular diamond colour is white. This is because a colourless diamond allows more light in, making for a more “sparkly” diamond.
The colour of a diamond also has its own grading system, ranging from D – Z. A white Diamond would be graded ‘D’, while a coloured one would be labelled ‘Z’.
It’s important to note that blue diamonds have a different grading system.
3. Clarity
The “clarity” of a diamond refers to its purity. Diamond clarity is graded from IF (Internally Flawless) to I3 (Level 3, Included, or including blemishes).
Naturally, a diamond may become impure with time as it is worn. This results in blemishes, or external marks, which may be noticeable when selling. That’s why the purer a diamond, and the better it’s condition, will affect it’s value.
At YL Diamonds, we use the latest technology to asses the clarity of a diamond. Though the naked eye will reveal part of a diamond’s worth, using technology that can magnify the diamond help us to better understand the diamond’s clarity.
4. Cut
The cut of a diamond also determines its price. But, the cut of a diamond is in the hands of who crafted it. So, when selling your diamond, it is important to keep this in mind.
Diamonds come in various shapes – from round or princess cut diamond rings, to cushion and emerald diamond shapes. The cut of the diamond is valued in terms of how light reflects through the cut, its symmetry as well as its proportions and polish.
When buying or selling a diamond, it is important to remember that the cut of a diamond will heavily influence its price.
Valuing Diamonds Using a Diamond Certificate
A diamond’s grading certificate is a valuable document which helps us determine the price of your diamond. At YL Diamonds, we have a particular interest in buying GIA, HRD and IGI certified diamonds. This is because these are considered the most reputable and renowned certified diamonds.
A diamond certificate verifies what you have bought or are selling is natural – or, the real deal. But, that’s not to say we can’t value or buy diamonds that don’t have a certificate.
So, if you’re looking to sell a diamond without an original certificate then get in touch and we’d be happy to help find its worth.

Joseph was amazing so great and personable to deal with I was worried about selling my diamond rings in the UK but I filled out the online enquiry form and Joseph got back to me within a hour quoting a price and I had already done research and enquired other places. Joseph beat them all hands down and not only that was polite to deal with and not aggressive like other diamond dealers he was polite friendly and professional. All his reviews are flawless and he totally lived up to them I felt privileged to have found his website and be able to deal with him. I sold my 2 diamond rings and upgraded them both to bigger stones and the quality of the stones it’s out of this world I’ve always done my diamond dealing in Dubai and Joseph totally beat that whole experience the stones are beautiful and he involved me in the selection process to make sure the diamonds were right. I even wanted a particular setting for the emerald I upgraded to and he made that happen. I can’t explain how happy I am don’t delay work with Joseph whether it’s selling or looking for a new piece he will help you every step of the way.Posted on Josh Chaubert-CooperTrustindex verifies that the original source of the review is Google. I used YL Diamonds to help design an engagement ring as well as trading in another ring. I was extremly impressed with the professionalism of Joseph and his white-glove approach. He really understood what I was looking for and worked closely with me to make sure the finished product was exactly what I wanted. I have dealt with a number of firms in Hatton Garden (with mixed results) and I'm just so very grateful to have found YL Diamonds. The ring is gorgeous and my fiancee was very happy to say the least.Posted on Jorna MiahTrustindex verifies that the original source of the review is Google.
