Guide How to design a custom engagement ring (without a design degree) What to decide first, what a CAD render should show you, and the three measurements that prevent an expensive mistake. Read Guide Moissanite vs diamond: the differences you can actually see Refractive index, dispersion, hardness and price — plus what happens in daylight versus a jewellery store. Read Guide Lab-grown vs natural diamonds: what is actually different Same crystal, different origin. What that does to price, certification and resale — and what it does not change. Read Guide Moissanite carat vs size: what you actually see on the finger Carat is weight. What changes the look is millimetre spread — and moissanite is lighter than diamond, so the numbers diverge. Read Guide Wedding band width: 2 mm, 4 mm, 6 mm or 8 mm? Width is a comfort decision before it is a style decision. What each width feels like after a year. Read Guide How to match a wedding band to an engagement ring Flush, curved, chevron or open — the decision is set by the gallery height, not by the width. Read Guide Engagement ring settings explained: prong, bezel, halo, pavé What each setting costs, how much stone it shows, and how it survives daily wear. Read Guide Metal guide: 925 silver, 9K–18K gold and platinum What each metal actually is, how it wears, and where the money goes. Read Guide How to measure ring size at home (accurately) The paper-strip method, the ring-diameter method, and the three reasons your first measurement is usually wrong. Read Guide IGI certificate explained: what the report actually tells you Report number, 4Cs, growth method, inscription — and the two numbers most buyers never check. Read Guide GRA certificate explained: what a moissanite card covers A GRA card is a grading card, not a laboratory report. Here is what it states and how to verify it. Read Guide The 4Cs for lab-grown diamonds (and which one to trade) Cut beats colour beats clarity beats carat — with the specific thresholds that matter at each size. Read
