What to check in your bespoke engagement ring valuation

Ring Valuation

Turn your engagement ring sideways. Perhaps the diamond sits low enough for a wedding band to slip alongside it, or there is a small sapphire tucked beneath the centre stone. You know why that detail matters. If someone had to remake your ring from its paperwork alone, would they know it was there? At Smith […]

Natural or Lab Grown Diamonds in Hatton Garden 2026

Natural or Lab Grown Diamonds

The question buyers ask me most often is whether lab grown diamonds are real. It is the wrong question. They are real diamonds, the same crystallised carbon, the same hardness, the same fire. After 20 years around the Hatton Garden trade I can tell you the honest decision is not about authenticity at all. The […]

How to Insure and Value a Hatton Garden Ring Purchase

Insure and Value

A receipt proves what you paid for a ring in Hatton Garden. It does not prove what the ring is, and it does not tell an insurer what replacing it would cost. Those 2 jobs belong to a proper valuation, and the gap between the documents catches buyers out every year. Ring insurance and valuation […]

Rhodium Plating

A white gold wedding band comes back to a Hatton Garden counter with a warm tint at the base of the shank and a bright top. Nothing has gone wrong with it. The rhodium plating has worn where the ring meets the palm, and the alloy underneath is showing through. Smith & Green Jewellers is […]

Oval Engagement Rings Explained From Bow Tie to Setting

Oval Engagement Rings

An oval diamond looks larger than a round one of the same weight and flatters the hand, but two things decide whether it is beautiful: its proportions and its bow tie. Neither appears as a grade on the certificate, so both have to be judged by eye.

Birthstones by Month and the Stones That Tell Your Story

Birthstones by Month

Every few days, someone stands at our counter at 9 Hatton Garden and asks the same quiet question: what is the stone for a May birthday, or an October one, and does it actually mean anything. Birthstones by month are one of the oldest gift traditions still alive in jewellery, and one of the most […]

Mens Ring Sizes UK and How to Measure a Ring That Fits

men ring sizes Uk

The most common emergency in our workshop is not a broken clasp or a lost stone. It is a groom two weeks from the wedding holding a band that will not pass his knuckle. Mens ring sizes UK follow a letter system that runs from A to Z and beyond, and men typically sit in […]
