Testimonials

Leigh S

I was incredibly excited to start unwrapping our rings when they arrived yesterday! The packaging is lovely, the information and letter from Alice Herald is great and very helpful. But the rings! They are beautiful! I am going to find it very hard to resist wearing mine before our wedding! Beautifully delicate, but simple. Just how we envisioned our rings to be.

I was recommended your site by my Maid of Honour as she knows of another couple who have sung high praises of 1791 Diamonds. And I'll be joining that chorus with sharing the positive, consistent, friendly and amazing service you offer. Your rings are divine!

Thank you, Erika, for your amazing help throughout this whole process. Usually all things wedding related are meant to be stressful - but you have definitely eliminated that element for us when it has come to buying our wedding rings :)

Kindest regards,

Leigh!

Hey Ardouin,

I really big thank you for all your hard work getting the ring to Hong Kong in time.

My good friend got the package on Thursday and ended up bringing it on a boozy night out with him not knowing the true contents of the package eeeekkkk haha!

The proposal went exactly like I was hoping for on top of a mountain overlooking an Island I grey up on. G didn't see it coming a mile away! She absolutely loves the ring and wouldn't want to change a thing about it. And to make everything just perfect the fit of the ring is spot on!

So a huge thank you from myself and G.

Cheers

Jason

Duchess Engagement Ring Review

Simple elegance defines the Duchess diamond engagement ring from 1791 Diamonds. The Duchess features a lovely marquise diamond set across a band of either 18kt yellow gold, 18kt white gold or platinum.

The distinctive oval shape of the marquise diamond offers a stunning alternative to the traditional round brilliant diamond shape for diamond engagement rings and is particularly well suited to someone with long, slender fingers. An added advantage of this fancy cut is a marquise diamond tends to emphasize its carat weight, making it appear much larger than it actually is; the result is a striking diamond ring for less cost than other traditional diamond cuts.

The marquise diamond cut is said to have been commissioned by Louis XIV to commemorate the smile of his beloved Marquise de Pompadour, and the Duchess design certainly encapsulates a regal and romantic air.
