Lab-grown vs Naturally Mined Diamonds

Whether grown by nature or science, both are real diamonds. Same brilliance, same beauty, different origins - here's what actually sets them apart:

Lab-grown vs Naturally Mined Diamonds — Whether grown by nature or science, both are real diamonds. Same brilliance, same beauty, different origins - here's what actually sets them apart:
Lab-Grown Diamond Naturally Mined Diamond
Origin

Created in a controlled laboratory environment using High Pressure High Temperature (HPHT) technology, replicating the conditions under which natural diamonds form.

Formed deep within the Earth's mantle over billions of years under extreme heat and pressure, then brought to the surface through volcanic activity and extracted through mining.

Chemical composition

Pure crystallised carbon (C) with the same cubic crystal structure as a natural diamond — chemically, physically and optically identical

Pure crystallised carbon (C) in a cubic crystal structure, often containing trace elements such as nitrogen or boron which can affect colour and type classification.

Sparkle level

Maximum - the most brilliant cut in existence, designed entirely to maximise light return and fire.

Very high - nearly as brilliant as a round, with a soft elongated shape that catches light beautifully from every angle.

High - a warm, romantic sparkle with larger facets that create a distinctive pillowy flash of light.

Subtle - long, open facets create a mirror-like hall-of-mirrors effect rather than sparkle. Elegant and understated.

Very high - combines the brilliance of a round with an elegant pointed tip for a striking, lively sparkle.

High - sharp geometric lines with excellent brilliance, giving a bold, modern flash.

High - an eye-shaped cut with exceptional brilliance and a dramatic, elongating effect on the finger.

High - a modern take on the classic cushion, with larger facets and a soft crushed-ice sparkle that feels effortlessly current.

Very High - a rectangular shape with the brilliance of a round cut, combining the best of the emerald and round brilliant for exceptional fire and light return.

Looks larger than carat

Forgiving of inclusions
Best for

Suits all finger shapes - the ultimate universally flattering cut. For those who want a classic, universally loved engagement ring that never dates.

A modern yet classic engagement ring on any finger shape, the oval is Fenton's best-loved cut. Ideal for shorter or wider fingers - the elongated shape creates a beautifully lengthening effect.

Suits most finger shapes, particularly those with wider fingers who want a softer, less angular look, with a nod to vintage jewellery traditions.

Those with a cool, confident aesthetic who appreciate clarity and architectural elegance over sparkle. Ideal on longer, slender fingers - its open, rectangular face showcases elegant hands beautifully.

Those who want something distinctive and feminine, with a beautifully unique silhouette. Excellent for shorter fingers - worn with the point facing outward, it creates a striking elongating effect.

Those who love clean geometric lines and a bold, contemporary feel. Suits longer fingers well - the sharp corners and square shape look balanced.

Those who want to make a statement - dramatic, elongating, and unlike anything else. The most elongating cut of all - transformative on shorter or wider fingers, creating the illusion of length.

Those who want the shape of the moment, as seen on Miley Cyrus. Blending vintage warmth with modern cool. Flattering on most finger shapes - the soft elongated form offers the lengthening benefits of an oval with a more relaxed, pillow-like silhouette.

Those who want the elegance of a rectangular stone without sacrificing sparkle - a brilliant alternative to the emerald cut with far more fire. Suits most finger shapes - the rectangular silhouette elongates like an emerald cut, while the brilliant faceting keeps it lively and flattering on wider fingers too.

Ring and Band Metal Guide

To protect the longevity of both rings, we recommend choosing the same metal for both your engagement ring and wedding band - different metals worn together can cause premature wear over time.

The Romantic Choice
Character

A naturally white metal that will never fade or tint, platinum is a prestigious choice for an engagement ring. Its density gives rings a satisfying weight and ensures stones are held with exceptional security.

The warmest of the three metals, 18k yellow gold has a rich, luminous tone that complements all skin tones. Its classic appeal makes it a timeless choice with a contemporary edge.

With its soft, blush hue, rose gold has a distinctly romantic and feminine character. The copper alloy gives it its signature warm pink tone, making it one of the most distinctive metal choices.

Hardness

Hypoallergenic

Contains copper, which can irritate sensitive skin

Aesthetics
How your metal looks and ages over time is just as important as how it feels.
Patina over time

Develops a natural patina — a subtle satin sheen — over time. Many wearers love this lived-in look, and it can always be repolished to restore its original bright finish.

Retains its warm golden colour beautifully over time with minimal upkeep. Light scratches can be buffed out easily, and the colour remains consistent throughout the metal.

May deepen very slightly in hue over time as the copper content oxidises, adding warmth and depth. This natural evolution is considered part of its charm.

Best paired with
