A website is a good place to start and a poor place to finish. Photographs and videos are shot under controlled lighting, and no screen reproduces what a diamond actually does with light in a room. Comparing two stones side by side takes about ninety seconds and tells you more than an hour of browsing. If you can't come in, we'll show them to you on camera — but see them next to each other somehow.

No. A well-cut diamond can look larger than a heavier stone with poor proportions, because a badly cut diamond carries its weight down in the depth where nobody sees it. Two diamonds of identical carat weight can differ noticeably in how big they appear face-up. Spend on cut before you spend on size.

Yes. A report from a respected independent lab tells you what you're buying and protects you if you ever insure or sell it. Buy certified — just don't buy the certificate.

Because the certificate and the beauty are two different questions. The report verifies the facts — carat weight, measurements, color and clarity grades, and that the stone is what the seller says it is. That matters, and you should never buy without it. But a report is a description, not a verdict. You need it for the facts. You need eyes for the rest.

No, and this is the heart of it. Grades describe measurable properties. They don't measure transparency, they don't capture the difference between two stones both graded Excellent, and they can't tell you how a diamond looks across a dinner table. Give us a hundred diamonds with identical grades and one or two will be genuinely exceptional. The report won't tell you which ones.

Usually because it's easier. Selling from a list requires no inventory, no gemologist, and nobody who can look at a stone and judge it. Grades are also simpler to compare than beauty, which makes for a simpler sale. We don't think it's dishonest. It just isn't the same as someone choosing a diamond for you.
