Cut:FANCY CUT
'Fancy' diamonds (anything non-round) are not given a cut grading by the GIA, because there are too many variables to calculate within these different shapes. Therefore Kensington hand-select only pear, oval, cushion, emerald, princess, radiant, asscher and marquise diamonds which have internal cut proportions we would classify as 'Excellent'. Any diamond not living up to our expectations of maximum brilliance and sparkle will be discarded.
Color:D
The highest grading. Rare, exceptionally colorless diamonds that look icy white in appearance.
Clarity:VS1
An excellent choice at a lower price point than VVS grades. A high quality diamond, with inclusions/blemishes that can be picked up under 10x magnification, but remain invisible to the naked eye. (Without magnification it would be impossible to tell a VVS1 and VS1 diamond apart.)
Certificate:GIA Certified
We only stock diamonds that have been certified by the GIA; the world’s largest and most reputable independent grading laboratory. They are recognised as the strictest graders of diamonds in the industry, giving you the peace of mind that you are always getting exactly what you paid for.

of whether you have purchased something or not.
If you don’t find the right option with us - that is no problem at all, and we wish you the best
of luck with your purchase elsewhere.
We guarantee a friendly atmosphere, and there is absolutely no pressure to buy.
If you are interested in making an appointment then please get in touch now, and we will be
delighted to welcome you soon.
Do you take precautions to stop the spread of Covid?
When you visit our showroom, you won’t need to interact with any other clients - it will just be
your group and our diamond specialist, for a one-on-one consultation.
We always wear a face mask, keep a safe distance where possible, and take the utmost
responsibility to clean and sterilise the office between client appointments.
Can I do a zoom appointment instead of visiting the showroom myself? Or can I buy
online?
All our products are available to buy online through our e-commerce store.
However given the expensive, and sometimes bespoke nature of the beautiful products at hand - we
understand most clients would like to see the diamonds with their own eyes before committing to
purchase.
If for whatever reason you would prefer to arrange a consultation online instead of coming to our
showroom yourself, we would be more than happy to facilitate this by scheduling an online Zoom
call at your convenience.
What is your returns/cancellation policy?
After ordering your selected diamond, we offer all clients an appointment to visit our showroom
and see the diamond for yourself. If for whatever reason it turns out to not be what you were
expecting, there is no obligation to continue with the purchase and we will happily help you
find an alternative from our other diamonds in stock, or cancel the transaction.
Upon confirming you want to proceed with the diamond purchase, customers are expected to pay a
50% deposit of the sale price immediately, and the remaining 50% upon collection of the finished
piece.
A non-refundable 10% cancellation fee shall apply during the acceptable cancellation period of 48
hours after payment of the initial deposit. However due to the hand made, bespoke nature of our
products - after 48 hours the sale cannot be cancelled and is considered final.
We always operate in good faith and aim to work with our customers to find a solution to any
problem, however refunds will be made at Kensington Diamonds own discretion.
Do You Offer free resizing?
Classic platinum rings can be easily resized and we offer this service to our clients free of
charge.
However care should be taken when ordering eternity rings or engagement rings containing a
significant number of side-stones, as resizing may be more difficult and require re-setting.
If you are buying for a surprise gift for your partner, and do not know his/her ring size in
advance - get in touch and we will do everything we can to help you find the correct size.
How long does it usually take to receive my finished product?
We aim to complete every piece within one month of ordering, as standard.
However if you are creating a custom design which will require a bespoke mould - the date of
completion will likely be 5-6 weeks.
Regardless, if you are in a hurry or really need your piece to be finished by a specific date, we
will happily work with you and offer options which can be delivered quicker if required.
