Bright and sparkling

At Parchment Jewellers we believe that when choosing a diamond the customer should receive the brightest, clearest and most sparkling stone, one whose quality will never fade.

Every diamond is unique

All diamonds, whether lab created or mined, share certain features that allow us to compare and evaluate them. These features are called the 4Cs: Colour, Clarity, Cut and Carat. The beauty of a diamond is determined by all 4. The variations are what make it unique.


The Diamond Colour Scale extends from D (colourless) to Z (light yellow or brown). Gem quality stones are those that have a colour rating from D to G.

The Diamond Clarity Scale includes eleven clarity grades ranging from Flawless to I3. Gem quality stones are those that are VS and above.

The Diamond Clarity Scale


A polished diamond’s beauty lies in its complex relationship with light, which produces a combination of fire and brilliance. It is the cut of the diamond that determines this.

Carat Weight

One carat equals 200 milligrams in weight. For diamonds under one carat, each carat is divided into 100 points – similar to pennies in a pound. 0.75 ct. = 75 points, 1/2 ct. = 50 points.

Our Parchment Promise

Ethical stones
We only supply ethically sourced diamonds of the highest quality. We can also source certificated lab created diamonds for customers who prefer non mined stones.

Gem quality
All diamonds are ‘gem’ quality stones as opposed to lower ‘industrial’ quality stones, which should not be sold in jewellery. Parchment Jewellers’ curated quality is G colour, VS clarity minimum.

Chosen together
We encourage you to view your diamonds loose without any obligation to buy before deciding what to order. We are happy to take you through the principals of gemmology, showing you your diamond under a 10x magnifying glass to demonstrate the importance of colour, cut and clarity.

“Giving jewelry is always a pretty special event, so it’s really important that the process of choosing and buying a gift is just as rewarding.

You receive one-to-one service that places the focus on giving you insight into the process of choosing and buying diamonds that are good quality and ethically sourced, and then offering a massive amount of flexibility as to the final design options. There’s no pressure, nothing is too much trouble and you end up with a very personal service that only adds to the feel good factor of purchase itself. Owner David Hill is to be complimented for a great business and for taking the extra effort to place his customers first.”

“I wanted to write to say how delighted I am with my ring – it is beautiful and I’m looking forward to showing it off over Christmas!

“Thank you for all your advice throughout – I think I may have said to you I was a little worried about having the ring made as opposed to buying something ready made but having shared with you what I had in mind the decisions were quite easy really and the result everything I had hoped for.”
D. Pammer, Winchester

“I thought I’d drop you a quick message to express my gratitude and delight at the bespoke diamond ring you made for me.

“Not only was I delighted that you were able to make and design it within such a tight timescale but you had it ready early and it turned out better than I expected. I’d like to thank you for the time you spent and advice you gave us at the initial consultation whilst finalising the design. What’s more my ring is unique and I love it!”
N. Burgess, Tadley
