The Richmond - Emerald

We value our client's privacy, and pride ourselves on providing the absolute highest level of service in a comfortable, friendly environment at our showroom in Omotesando, Tokyo.

At Kensington Diamonds we believe that every customer deserves our full undivided attention, therefore we operate on an appointment only basis.

You will be welcomed in for a one-on-one consultation of up to one hour; where we will guide you exactly what to look for, over a glass of champagne. Explain how to get the biggest diamond available within your budget, and show you our most popular recent designs.

There is no absolutely pressure to purchase, and we are more than happy to answer any questions you have.

Each and every product we produce is handmade here in Tokyo, by master craftsmen with decades of experience.

Our business is based on delivering beautiful, yet secure and sturdy pieces to our clients that will last a lifetime. We are exceptionally proud of the hours of world class Japanese craftsmanship that goes into each one.

We understand that most men enter the process of purchasing an engagement ring without knowing the first thing about either diamonds, or what their fiancé to be is actually hoping for...

Our job is to simplify the process for you entirely. At the consultation phase we will teach you everything you need to know about diamonds, happily answer all your questions, and offer recommendations based upon the information you provide us.

Over the next steps, we will work closely together until your finished engagement ring is exactly what she is dreaming of. Let us be your guide and do what we do best, which will in turn remove any stress or hassle from the process for you.

We aim to accommodate any client request. If you want to make a product that we don’t have listed on our site, simply get in touch by telephone / email or Instagram message, and we would love to discuss it with you further.

Any diamond you see on our site can be used to create earrings, a necklace or a piece for yourself to celebrate a recent achievement or life milestone. Our jewellery is not reserved solely for bridal occasions.

At Kensington Diamonds we abide by a strict code of conduct to ensure that every single diamond we sell our customers has been legally procured from an ethically responsible source.

We buy our diamonds exclusively from the world's largest and most-established producers, who are 100% compliant with the regulations laid out in the Kimberley Process. We are proud to be a morally responsible company.

Kensington Diamonds offers clients the opportunity to build fully bespoke, one of a kind piece. If you have a unique idea in mind but no design experience, our creative team is here to help.

Allow one of our design experts to turn your concept into a fully detailed blueprint - before working with you every step of the way until we can deliver you your dream finished product.

Our business is nothing without happy clients - so please take their word for it, not ours.

We are very proud of our manufacturer's craftsmanship and ensure only the highest quality materials go into creating our jewellery. Therefore we are happy to offer a lifetime warranty to guard against any damage as a result of manufacturer defects.

At an appointment at our Omotesando showroom, you will be able to:

View or try on different diamond jewellery of all carat sizes until you find exactly what you are looking for. Enjoy a glass of champagne/cup of tea, as you are welcomed to ask as many questions as you have to one of our diamond experts. Benefit from our one-on-one advice of how to get a bigger, better diamond for your budget. We promise that even if you don’t proceed with us, you will receive extremely useful guidance on how to get the best diamond.

We want you to enjoy yourself and leave our showroom with an experience to remember, regardless 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.

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.

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.

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.

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.

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.
