Frequently Asked Questions

Below are the answers to our most commonly asked questions. Should you want to find out more please feel free to Contact Us and begin your Pragnell experience.

A round 1 carat diamond typically measures around 6.4–6.5 mm in diameter, creating a beautifully balanced presence on the hand.

Cut depth, table size and overall proportions can dramatically influence face up appearance, making one 1 carat diamond look larger or smaller than another.

No — “carat” measures weight (0.2 g) , not dimensions. Shape and cut determine how the diamond looks on the hand, which is why equally weighted stones may vary visually.

A 1 carat diamond offers a timeless sense of balance — visually expressive yet refined — and remains one of the most sought after engagement ring sizes internationally.

Yes. Oval, marquise and pear shaped diamonds often appear bigger due to their elongated silhouettes, which enhance their face up spread.

Cut quality plays the most significant role in beauty and value, followed by colour and clarity. A well cut diamond maximises brilliance and can even appear larger.

Buyers often achieve excellent value by choosing slightly lower clarity or colour grades, exploring fancy shapes, or selecting stones just under 1.00ct for similar presence at a more accessible level.

Pragnell works solely with natural, fully traceable diamonds, each verified and sourced in accordance with the Kimberley Process to guarantee they are conflict free. Through ethical partnerships, including those in Botswana, our diamonds support responsible mining communities while upholding the highest standards of provenance and sustainability.

On many UK finger sizes, a 1 carat diamond appears beautifully proportionate — offering presence and sparkle without overwhelming the hand.

Every Pragnell diamond is hand selected by our gemmologists for its exceptional fire and clarity, then crafted into settings ranging from timeless solitaires to expressive heritage designs.
