Want to customise this design?
Our expert jewellers create stunning custom designs — from subtle modifications to completely bespoke creations.
Crafted with Intention
Grace, brilliance, and enduring romance — the Ecco Round Diamond Halo Engagement Ring in 18ct white, yellow or rose gold captures everything an engagement ring should be.
At its heart lies a round brilliant-cut centre diamond, perfectly framed by a low-set halo of micro claw-set diamonds that radiate light from every angle. The low-profile setting ensures the ring sits gracefully close to the finger, offering both exceptional comfort and understated elegance — ideal for daily wear without compromising on sparkle.
The finely detailed pavé-set diamond band continues halfway around the ring, creating a seamless flow of brilliance that accentuates the central diamond’s beauty. Each Ecco is meticulously hand-finished in your choice of 18ct white, yellow, or rose gold — each metal bringing its own unique charm:
-
18ct White Gold: A timeless, modern classic with a cool, mirror-bright finish.
-
18ct Yellow Gold: Radiant warmth and vintage allure in perfect harmony.
-
18ct Rose Gold: A soft, romantic hue that glows with feminine elegance.
Available with your choice of natural or lab-grown diamonds, every Ecco ring is made to order — crafted to reflect your personal love story with a brilliance that lasts a lifetime.

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.
Are lab-grown and natural diamonds both certified?
Yes. Every diamond we supply is independently graded — GIA for natural diamonds, and GIA or IGI for lab-grown. The original lab report is shipped with your ring.
What if it doesn't fit?
Complimentary resizing within the first 60 days. Not sure of your size? Select 'Not sure' when ordering and we'll include a complimentary ring sizer.
