Showstopper engagement rings
This beautiful 6.00 carat solitaire is the largest ring you can order on the website, if you want to go bigger, get in touch, we can go as big as your imagination. This ring is £6995 which is a good yardstick for price, do bear in mind though, some cuts are rarer than others, and old cuts are considerably more expensive and harder to source.

After finding Katherine James Jewellery on Instagram, I knew immediately where I would purchase my engagement ring. I exchanged emails and messages via Instagram before popping in to meet with Claire. From the wealth of advice to the warm presence, the service received from both Claire & Katherine was amazing! My ring is everything I wanted and more! Thanks ladies 😘

I have just received the most fabulous ring from Katherine James Jewellery.
It looked beautiful on their website, but when it arrived it surpassed my expectations. Added to that, their customer service is excellent. Thank you!

Katherine James Jewellery provides a truly personal service. Nothing is too much trouble...photos, sizes, etc. Sizing, if needed, is swift. Love getting my parcels! I’ve bought several pieces from her over the past three years or so ranging from a little unusual brooch to big, whopping sparklers. I’ve returned items too, and there is absolutely no issue. Big, massive thank you from me.

Frequently Asked Questions
Product
Lab Grown Diamonds are carbon crystals, just like their natural counterparts. They are grown in a lab in weeks, instead of in the Earth over billions of years, Lab Growns have the same optical, physical, and chemical properties, with none of the environmental concerns, and are available at a far more affordable price point. Read more about them here.
No, the only real giveaway is size, if you go big, and spend the average UK spend on an engagement ring, £2000, instead of an average 1/2 carat in Naturals, you’re now looking at a 1.50 - 2.00ct. And not just an average 1.50 - 2.00ct, an exceptionally bright and sparkly F VVS Diamond.
KJJ Diamonds
We are based in Hatton Garden, London, our address is 15, Greville Street.
I’m now 41 and I’ve been buying and selling jewellery since I was a girl. I’ve been selling jewellery online for nearly two decades, starting by selling some of my own collection on eBay, and I had a Facebook page too, then as it grew we built the website kjj.rocks, which specialises in antique and vintage jewellery and one off coloured gemstones, and kjj.diamonds is sister site to kjj.rocks. We’ve got reviews all over the internet, on trustpilot, google, Facebook, and insta, and we do have a large following on Facebook and Instagram.
We are by appointment only at our Hatton Garden office, please get in touch here to make an appointment.
Online - we are available to answer any questions you might have usually within a few hours.
Because most of our .diamonds pieces are made to order, we won’t always have exactly what you were looking at in stock and at the office. We will always have a few pieces that we’re working on, and some sample stock, so you’d be very welcome to pop in and say hi, and have a look at what’s in production to get a feel for what we do before you order. We can also help with sizing, and narrowing down exactly what you’re after. To make an appointment to pop in, contact us here.
