Diamond Education

Diamond Education

Buying a diamond should never feel like a leap of faith. This guide explains — in plain language — what actually determines a diamond's beauty and value, so you can walk into any conversation with confidence.

The 4 Cs

Cut. The most important C, and the one most often overlooked. Cut is not the shape of the stone — it is how well the facets are proportioned and angled to return light. A superbly cut diamond of modest size will out-sparkle a larger, poorly cut one. When budget forces a choice, protect the cut grade first.

Colour. Diamonds are graded from D (completely colourless) down the alphabet as traces of warmth appear. The differences between neighbouring grades are subtle; most people cannot distinguish a D from an F, or a G from an H, once the stone is set. D–F is considered colourless; G–J near-colourless and excellent value.

Clarity. Clarity grades (FL, IF, VVS1–2, VS1–2, SI1–2, I1–3) describe internal characteristics visible under 10× magnification. The practical question is whether a stone is eye-clean — free of inclusions visible to the naked eye. VS and better stones are almost always eye-clean; well-chosen SI stones often are too.

Carat. Carat measures weight, not size — and prices jump at the round numbers (0.50, 1.00, 1.50 ct). Buying just under a threshold (say 0.90 ct instead of 1.00) looks nearly identical on the hand and can save meaningfully.

Diamond Shapes

Round brilliants deliver maximum sparkle and hold value best. Ovals and pears look larger for their weight. Princess and cushion cuts offer geometry with fire; emerald and Asscher cuts trade sparkle for glassy, architectural elegance; marquise and heart shapes make a statement. Shape is taste — there is no wrong answer.

Lab-Grown vs Natural

Lab-grown diamonds are real diamonds — chemically, physically and optically identical to mined stones, and graded on the same scales. They typically cost 50–80% less than natural equivalents, which buys a dramatically larger or finer stone for the same budget. Natural diamonds carry billion-year origins and stronger long-term value retention. Neither is "better": it is a values-and-budget decision, and we stock and set both, fully disclosed.

Metals

10K gold (41.7% pure) is the hardest-wearing and most affordable. 14K (58.3%) is the everyday sweet spot of durability and richness. 18K (75%) offers the deepest colour for fine pieces. Platinum is denser, naturally white and hypoallergenic — the premium choice for engagement work. Yellow, white and rose tones are a matter of skin tone and taste.

Caring for Your Jewellery

Clean pieces gently with warm water, mild soap and a soft brush; avoid chlorine and harsh chemicals; store pieces separately so diamonds don't scratch softer metals; and have settings checked periodically — we're happy to help.
