I've seen a ring I love on your site. Can I see an example of it at home?
At Pobjoy Diamonds we understand how important it is for our customers to see and feel jewellery - especially a piece of jewellery as precious as an engagement ring.
That's why we offer replica rings of many of our designs to try first - at home or at our visitor's suite.
These include an eclectic mix of engagement and eternity ring designs along with wedding bands for him and her.
All our custom made and bespoke rings include a free re-sizing within six months of purchase.
Please note that some ring designs are not so easily re-sized, particularly designs featuring diamond set shoulders and full eternity rings.
When a ring is resized certain markings and personal text inside the ring may reduce in intensity due to the papering and re-polishing process involed.
In some instances it may be deemed more appropriate to add comfort beads to the inside of the band, for example if the ring is very slightly too large or has a tendency to gradually swivel when worn.
Comfort beads are two small polished rounded "bumps" expertly added to the ring in matching precious metal and cannot be seen when the ring is in place.
Yes. Every item of fine jewellery and loose diamonds published on our site can be purchased online using our secure checkout process.
Please bear in mind that many items displayed, such as diamond set eternity and engagement rings, are made to order and sized to fit. Please see our product pages for details or contact us to confirm expected timelines.

Are your diamonds independently graded and certified?
Yes. All our individual diamonds of 30 points (0.30 carat) and over are independently graded and certified.
Nearly all our diamonds are graded and certified by either the Gemological Institute of America (GIA) or the International Gemological Institute (IGI).
Yes. All the certified diamonds we sell have been screened and sourced from legitimate sources not involved in funding conflict, incompliance with UN Resolutions and corresponding national laws of the United Kingdom. Our sources guarantee that thesediamonds are conflict free and confirm adherence to the WDC SoW Guidelines.
It is also possible for you to request specific geographical origins when choosing your diamond.
You can read more about our diamond sourcing in the link below.
The independent grading report or certificate is perhaps the most important verification of the diamond you buy from us.
This grading report provides a myriad of details about your chosen diamond.
While some retailers provide their own grading report or that of a lesser known grading institute, the specification of your chosen Pobjoy diamond is completely dependable.
This is because it has been compiled by one of the most respected third party grading institutes.
You are also able to verify the details of your chosen diamond online with the institute that has graded it.
Yes. Our online search facility provides access to over 500,000 certified diamonds from all over the globe.
You can filter your search by diamond shape, colour, clarity, cut and carat weight.
You can also apply more advanced filters such as table and depth ratios.
It is well worth reading our diamond guidance, tips and advice which you can find here on our website.
If you would like some assistance, whether over the phone, by email or at our visitors suite, just reach out to us and we will be very happy to help you.

If you are ordering from outside of the UK please contact us first as the 20% VAT element may not apply. Your purchase may instead be subject to local sales taxes and/or duties.
What does all the information included in the grading report actually mean?
Good question! At Pobjoy Diamonds we take care to remember that most people do not buy diamonds on a regular basis.
At first glance the diamond grading report can look complex and jargon heavy. Which it is.
Our 4C's guide is a good place to start. It is also worth seeing our diamond anatomy guide which explains some of the less talked about, but important, aspects of a diamond..
Do different colour and clarity grades of a diamond have much of an influence on price?
Very much so.
For example, a diamond with colour D or E will be substantially more valuable than an equivalent size diamond of otherwise similar attributes, but with a colour grade of H or I.
Typically, the same applies to a premium clarity grade of VVs1 over a lower clarity grade of Si2.
This may prove crucial for valuation and insurance purposes later on.
Eyeclean means that the diamond does not display any visible inclusions or marks when viewed with the naked eye.
It is not however quantified directly within a recognised diamond grading report.
In this respect there is a degree of subjectivity involved when classifying a diamond as eyeclean.
Nevertheless, when filtering through diamonds by their key characteristics, a diamond which is described by the producers we source from as eyeclean is wholly reliable.
It is worth noting that a high grade diamond such as colour F with clarity VVs2 may be a great looking diamond but is not necessarily eyeclean.
Conversely, a lower colour grade of G with clarity of Si1 may be eyeclean.
Marks and inclusions within an eyeclean diamond will still be visible when viewed under 10 X magnification.
Some gem diamonds fluoresce, most commonly blue, to the concentrated long-wave ultraviolet radiation of an ultra violet lamp.
The degree to which a diamond fluoresces is measured and recorded as an "identifying characteristic" within your diamond grading report.
To establish what effect, if any, blue fluoresecenc actually has, the GIA conducted a controlled test of multiple round brilliant cut diamonds of colour grade D through to H. Some featured faint to medium fluorescence and some did not.
Gemologists and industry professionals along with inexperienced observers were asked to identify any visual differences in appearance between the stones.
Here is what the GIA found: “For the average observer, meant to represent the jewellery buying public, no systematic effects of blue fluorescence on the face-up appearance of the groups of diamonds were detected. Even experienced observers did not consistently agree on the effects of fluorescence from one stone to the next.”
Typically, brilliant cut diamonds with medium or strong fluorescence will be priced very slightly lower than equivalent cut, grade and carat weight diamonds without fluorescence.
Pobjoy Diamonds recommends choosing diamonds between colour grade D and H that have no or faint fluorescence.
In the case of smaller carat weights of colour H to J, some faint or even medium blue fluorescence is generally preferrable and may actually raise the overall appearance up a notch.
You would be most unfortunate if your diamond were to crack or chip.
However, a diamond is not entirely indestructible.
Diamonds with narrow pointed extremities, such as marquise or pear shape, do need to be set in such a way that they are well protected from knocks.
That is why we insist on using only the most robust prong settings, designed to adequately embrace these points and mitigate against damage.
Other diamond shapes are not entirely immune, however, to potential damage either.
Any larger carat weight diamond in an elevated setting will be marginally more exposed to trauma if worn without care. A diamond may contain, for example, slight fissures which can occur naturally during the formation process.
If the diamond suffers an especially violent trauma or repetitive, acute knocks against a very hard surface, this could cause damage to the stone.
Therefore, when combined with the risk of loss or theft, we do strongly recommend that you maintain adequate insurance cover of your diamond at all times.
What's the difference between an "old cut" and brilliant cut diamond?
An old cut (or Victorian cut) diamond is one which was produced several years ago.
When these diamonds were produced, the precision cutting techniques used today were not available.
Therefore, the amount of fire, brightness and scintillation is less evident when compared to more modern brilliant cut diamonds.
It was also considered that a polished culet (a flattened lower extremity - or tip - of the diamond) would allow more natural light in to the stone, thereby adding to it's overall sparkle.
Nowadays however, the culet is cut to be pointed, as it actually prevents the light entering the table and crown of the diamond (the upper area) from disappearing straight out through it's underside.
Diamond & Fine Jewellery
What is fine jewellery?
Fine jewellery is made exclusively from precious metals such as sterling silver, gold, palladium or platinum.
Items featuring gold plated on silver are considered fine jewellery.
Items featuring gold or silver plated on a base metal such as steel are not considered fine jewellery.
How can I keep my diamonds and fine jewellery looking fabulous?
Fortunately there are some simple tried and tested things you can do to keep your cherished jewellery in tip top condition.
Our jewellery care guide is full of ideas which are easy to follow and will cost you nothing.
For example, just by dipping your diamond ring in a bowl of hot water with a drop of liquid soap and rinsing off once a week will make it sparkle like new.
We also include a care intructions card with every item of jewellery we sell.
Rhodium plating is a precious metal and is a derivative of platinum.
It is extremely durable, silver in colour with a shiny finish.
Rhodium plating is a process that is used to apply a thin layer of rhodium to jewellery to lend a bright and hard wearing surface that is resistant to scratches and tarnishing.
It is usually applied to white gold or platinum. It is particularly effective in refinishing an item of jewellery which has been repaired, has aged or a re-sized ring.
Technically, it is an electroplating process and may be applied in different amounts of thickness.
What's the difference between .925 silver, sterling silver and silver colour?
Sterling silver is the same as .925 silver. This means that the metal consists of 92.5% silver with the remaining 7.5% being made up of other alloys such as zinc.
Without the addition of these other alloys, silver would be too soft and vulnerable to dents, abrasions and pitting.
When looking at jewellery, make sure that it is clearly described or marked as .925 silver or sterling silver.
Otherwise it may just be plated with silver or have a silver effect finish, thereby being much less valuable.
This means it will also be prone to discoloration, fading and leaving green or blue staining on your skin.
Melee diamonds are very small carat weight diamonds used in diamond jewellery and in the halos and shoulders of some diamond rings.
They are typically 0.25 carat (25 "points") or less.
Nowadays melee diamonds used in high quality jewellery are full cut diamonds. So they are essentially the same as larger diamonds, just smaller.
As with larger diamonds, they are graded by colour and clarity. The precision of their cut is just as important as it is with a larger diamond.
Typically, melee diamonds are traded within the industry in one carat packages. One carat of 10 point D-E colour/VS clarity melee diamonds will be much more valuable than one carat of 10 point H-I colour/Si clarity stones.
Are larger size melee diamonds much more valuable than smaller ones?
Larger melee diamonds are of course more valuable than smaller ones of the same colour and clarity.
But more specifically, one carat weight of ten F/VS grade melee diamonds (10 points each) is more valuable than one carat weight of twenty F/VS grade melee diamonds (5 points each).
As with larger diamonds of similar grade and overall specification, the increase in price in relation to carat weight is exponential rather than linear.
How do I know if I am buying the right size jewellery?
Within our product pages you can usually see measurements for each item expressed in inches and/or centimeteres.
If this is unclear or not provided for any reason, please do contact us and we will clarify these details for you.
To check your wrist size and to see the drop of a necklace when worn, just check out our sizing tools.
How does a lab grown diamond compare to an earth created mined diamond?
Lab grown diamonds and earth created, mined diamonds display identical optical properties and the same chemical structure.
While an earth created diamond evolves deep below the earth's surface over thousands of years, a lab grown diamond is created over several weeks, using a diamond seed as it's embryo.
The two processes are essentially the same. But by using highly specialised machinery and skilled technicians the natural creation process is replicated within a vastly reduced timeframe.
Can a diamond expert tell the difference between a lab grown and an earth created diamond?
Not with the naked eye nor with standard diamond inspection and verification equipment.
Under magnification of at least ten times, the lab grown certificate number nano inscribed around the girdle (the widest part of the stone) may be legible. The accompanying grading certificate is also of a different colour combination than the equivalent earth grown diamond report.
Otherwise, the only way a lab diamond can be told apart from the earth created variety is by using highly specialised fluorescence spectropscopy equipment.
Yes. You can search over 200,000 ethical lab diamonds on our site, each one certified by either the IGI or GIA.
As with earth created diamonds, you can choose between popular diamond shapes, specify colour and clarity grades and the carat weight you prefer. All our pricing includes VAT and insured free delivery within the UK.
Or you can arrange an appointment to our visitors suite and we will guide you through the process.
We also hold a selection of premium grade stones which are available for next day delivery.
How much less do lab grown diamonds cost than earth diamonds?
This varies according to such variables as the carat weight and grading quality of the two types of diamond being compared.
The rule of thumb is that the larger and better the grade you go, the greater the proportionate difference in price between the two types of stone.
For example, a 2.00 carat weight colour F, clarity VS1 lab grown diamond will be in the region of 25% to 30% of the price of a comparable earth created diamond.
In the case of a 0.30 carat G/Si1 grade lab grown diamond, approximately 35%.
Is there the same choice of lab diamonds as earth created diamonds?
Not for every shape and carat weight.
However, the advancement in lab growing techniques and expertise continues apace, with increased demand driving ever more perfect outcomes.
There is significant choice at the lower end of the lab diamond market - both in terms of smaller carat weight and inferior grades.
As the overall diamond grade improves and the carat weight increases, the sought-after superior quality lab diamonds we sell are less abundant and are in high demand.
How can I be sure my lab grown diamond will not look different over time?
The chemical composition of a lab diamond is the same as an earth created diamond, neither of which change appearanceover time.
For added assurance, it should be noted that the first lab grown diamonds were actually produced in the 1950's and have displayed the same enduring qualities as mined diamonds ever since.
Are lab grown diamonds really more ethical and sustainable to create?
Lab diamonds are created under controlled conditions and without directly extracting or disrupting the earth's natural resources.
Critics point out that the energy consumed in the growing processes, especially the HPHT technique, undermines the sustainability credentials of the lab grown diamond.
But as each process becomes increasingly efficient, this issue becomes less relevant.
Lab grown diamond enthusiasts point out that the amount of earth removed in the process of mining a single carat diamond is several tonnes, in addition to the energy consumed and the sometimes risky working conditions.
Do you offer bespoke services for lab grown diamonds?
Yes.
You decide which type of diamonds or coloured gemstones to incorporate in to your bespoke design.
Can I get an indication of price before progressing a bespoke commission with Pobjoy Diamonds?
Yes. We appreciate that cost is inevitably an important aspect of deciding whether to create your own unique piece of jewellery.
