Credit scoring is the process used by financial services companies to evaluate the credit risk of new applicants. This technique will be applied to your application for online finance. Credit scoring works by awarding points for each answer given on the application form such as age, income and occupation, together with information obtained from credit reference agencies.
This information allows consistent decisions to be provided, ensuring all applicants are treated fairly. Credit scoring does not discriminate on the grounds of sex, race, religion or disability.
All monthly payments are paid by direct debit from your personal bank account. Typically, the first payment will be due one month after the date of the finance agreement.

In addition to credit scoring, Novuna also takes into account confirmation of your identity, validation of certain application details, existing commitments and information held at the credit reference agencies. Though Novuna is unable to provide you with a main reason for declining your application, it is usually based on one, or a combination of the following:
What type of information do credit reference agencies hold about me?
Some of the information is public information, for example electoral roll, County Court Judgments and bankruptcies. Other lenders may also file information about accounts you hold with them for instance this could include your payment history and outstanding balance on these accounts. Any requests for credit, where a credit reference search has been undertaken, will also be filed, although the result of the request is not recorded.
How do I obtain a copy of this information?
Send a request to the relevant credit reference agency, together with details of all addresses at which you have lived over the last 6 years:
The above listed agencies will provide details of information relating to these addresses. If you believe that the information is incorrect, you can ask the agency to correct it.
Yes. We acknowledge that circumstances change and just because a previous application has been refused, it does not mean that a further request will automatically be turned down. We do suggest however, that you leave at least 6 months between applications.
If you have a complaint, please refer to our formal complaints policy and procedure. You also have the right to refer your complaint to the Financial Ombudsman Service.

IGI (International Gemological Institute) is an extremely well respected and world-renowned laboratory which specialises in grading diamonds and precious gemstones.
An IGI certificate is a real 'seal of quality'. This certificate will assure you that the diamond you have chosen is nothing less than it should be.
The value of a diamond is determined through an intricate process during which its gemmological makeup, rarity and quality are examined. This is the only real way of separating one diamond from another. Experts at gemmological laboratories, such as the IGI, use powerful analytical tools and have years of experience in grading diamonds.
The diamond you are buying has been through a rigorous testing process and the independent report/certificate you receive with your jewellery confirms its true qualities.
These certificates can also be validated on the IGI website. By entering your diamond certificate number on the IGI website, you will be shown a verified copy of the report that you have.
Does this make an IGI certified diamond more valuable?
Yes, a diamond with an IGI certificate is much more valuable and sought after than one without.
The IGI report, together with the online validation process, gives you peace of mind when you purchase your diamond. For any prospective buyers or new owners, it’s confirmation of the diamond’s authenticity and quality.
Is This Diamond Conflict Free?
Yes. All the diamonds we sell, including our IGI certified range, are conflict free.
Are IGI certified diamonds any different to other diamonds?
Yes, an IGI certified diamond is exactly what it says it is. Non-certified diamonds are not independently examined. Therefore, you must rely on the retailer’s opinion.
Why are IGI certified diamonds more expensive than SKD certified diamonds?
Because the IGI laboratory is an international, globally recognised laboratory. SKD is a London-based laboratory.

5-Year Warranty
At The Diamond Store, we take great pride in the quality of our jewellery. Every piece is skilfully crafted to last for many years to come. That’s why we offer a 5-year warranty against manufacturing defects in materials or craftsmanship.
What The Warranty Covers:
If a manufacturing fault is found in the way your jewellery was made, we will repair, remake, or replace it at no cost to you, within the first 5 years after purchase.
What’s Not Covered:
Our warranty does not cover accidental damage, wear and tear, loss, theft, or any work carried out by another jeweller. For example, damage from catching a ring on a door handle, losing an earring in a waste disposal unit, or vacuuming up a bracelet would not be covered. If a piece has been altered or resized elsewhere, the warranty becomes void.
Returns & Peace of Mind
We also offer a 30-day money-back guarantee (excludes custom-made items). Click here to view our full Return & Refund Policies.
Conflict-Free & Fully Certified

If Something Goes Wrong

What is the difference between our sustainable lab grown and conflict-free mined diamonds? Is it possible to tell them apart? We explain the differences in origin, quality and price between the two, so that you can make an informed choice.
They are exactly alike optically, physically and chemically.
The main difference is their origin:
Mined diamonds have been extracted from the Earth. They were created by Mother Nature from carbon atoms subjected to intense volcanic heat and pressure deep underground more than 3 billion years ago.
Sustainable lab grown diamonds are grown by scientists in a laboratory. They are created from a tiny shard of a mined diamond which is introduced to carbon atoms, under conditions which replicate the volcanic forces of Mother Nature.
Yes, lab grown diamonds are not extracted from the ground, which makes them environmentally sustainable and ethical as they conserve the Earth for future generations.
No. As long as you are buying mined diamonds from a reputable jeweller that abides by the Kimberley Process, your diamonds are ethical because they are conflict-free.
No, you cannot tell the difference between a lab grown diamond and a mined diamond by looking at them.
Therefore, to protect consumers, lab grown diamonds are branded with a microscopic laser mark to distinguish them from mined diamonds.
You cannot see this mark with your naked eye, but a jeweller will be able to see it with specialist magnifying equipment.
Yes, lab grown diamonds are more affordable than mined diamonds, giving you more carats for your budget.
You’ll find most of our popular jewellery ranges available in both options so you’ll be able to compare easily.
Bear in mind, however, that the precious metal setting plays a part in price. Silver is the most affordable, gold is a little more expensive, and platinum is the most expensive.
No, lab diamonds are not fake diamonds. Sometimes people confuse lab grown diamonds with simulants like cubic zirconia, which are not diamonds.
But this is not the case with lab diamonds. Gemmologists (the scientists who study diamonds and gemstones) classify lab diamonds, simply, as diamonds.
Learn more about the identical characteristics of lab diamonds here.
Mined diamonds and lab diamonds are quality-graded by gemmologists in exactly the same way using the Four Cs – Cut, Colour, Clarity and Carat weight.
Therefore, your diamond (regardless of whether it is lab grown or mined) will simply be graded at the quality it has, for example, Premium Quality, H/Si or E/Vs.
Having said that, since lab diamonds are more affordable than mined diamonds per carat, you’ll usually be able to access a much better diamond grade/quality for your budget if you choose lab grown.
“Better” is very subjective. It’s like cars. If someone asks you if an Aston Martin or a Ferrari is better, your answer would depend on your individual requirements.
It is the same with lab grown diamonds and mined diamonds.
Conflict-free mined diamonds are simply beautiful to look at and last a lifetime. A rare luxury created by Mother Nature, they come with the legacy of having been sourced from the Earth.
Sustainable lab grown diamonds are also stunning to gaze at, and they also last a lifetime. More affordable than mined diamonds, they are additionally sustainable and ethical.
In conclusion, both lab grown diamonds and mined diamonds are luxurious, beautiful and sparkling options – and they will both make wonderful gifts for a lifetime. Now, you simply have more choice.

High quality grades of diamonds.
Because we only sell 5 different grades of diamonds, all of which are of a high quality, the diamond you have already chosen won’t have any obvious flaws. But if your priority is for your diamond to have the best possible quality and sparkle, then investing in the next grade up makes good sense.
What would be the difference if you moved up a grade? Your diamond will look more radiant, gain in value – and you’ll get the very best quality for your budget.
Upgrading the size of your diamond means increasing its carat weight
The more carats a diamond weighs, the bigger it is.
The larger the diamond is, the rarer it is to find. That’s why an increase in size is a larger investment. When considering the size, think about what she or your friends wear and how you would like to compare.

White gold or platinum?
The main advantage of white gold over platinum is that it’s much more affordable. However, the disadvantage of white gold is that you may need to recoat your jewellery in rhodium once or twice a year. This adds to its overall cost over time, whereas platinum, more expensive to start with, will never require any maintenance.
