Four properties decide whether a diamond performs.
Cut, colour, clarity and certification. Each one is our standard, not the industry's. Together they deliver perfect light return: diamonds that shine brighter than the one next to them.
Colour. D to G natural, D to E lab grown.
Most eyes start seeing warmth around H. Every Monroe Yorke diamond reads as white on the finger. No tint, no apology.
Clarity. FL to VS2 natural, FL to VVS2 lab grown.
Below SI2 you start seeing specks. Hold any of our diamonds up to a lamp. You'll see nothing but light.
Certification. Independently graded, every time.
Every engagement ring centre diamond ships with an independent lab report. GIA for natural, IGI for lab grown. No in-house certificates, ever.
Your love story is unique — your ring should be too

Request Changes ›Frequently asked questions
Does the price include the centre diamond?
No — the price shown is for the setting only, hand-finished in your chosen metal. After you confirm this setting, we'll take you to our diamond search where you can select a GIA or IGI certified centre diamond — natural or lab-grown — that fits this design.
What centre diamonds fit this setting?
The diamond search will be pre-filtered to show only compatible stones — no guesswork, no returns for fit. Check the 'Compatible Diamonds' tab above for exact shape, carat, cut, colour, and clarity specifications.
When will my ring ship?
Every Monroe Yorke ring is hand-finished to order. Standard lead time is 6 weeks from the moment you confirm your centre diamond. Our dispatch days are Monday through Thursday — if the calculated date lands on a Friday, Saturday or Sunday, we dispatch on the following Monday.
Can I customise this ring?
The metal and karat are standard options — just select one above. For custom modifications like a different claw count, wider band, hidden halo, or mixed metals, book a free consultation and our master jewellers will quote the variation.
