Yes, if you're careful: ask for a GIA or IGI grading report, compare several dealers, get everything in writing and pay by a traceable method.
A grading report from the Gemological Institute of America describing a diamond's cut, color, clarity and carat — the standard reference when comparing stones.
There is no rule, whatever the old advertising said. What changes the number most is the stone: the same setting with a half-carat, a one-carat or a two-carat diamond spans an enormous range. Decide the budget first, then let the jeweler tell you which of the four Cs to compromise on to hit it — usually color and clarity before cut.
The Diamond District on West 47th Street is where you buy the stone closer to the trade, and where a custom setting costs less. Fifth Avenue is where you buy a brand, a box and a guarantee of the experience. Both are legitimate; they are answers to different questions, and the price difference on an identical stone can be large.
Three to six weeks is typical for a custom setting once the stone is chosen, and rush work is possible in the Diamond District for a premium. Ready-made rings from a boutique can be sized in a week or two. If there is a date involved, say so at the first appointment rather than the last.
Policies vary sharply and custom work is usually final. Get the return window, the resizing policy, the appraisal and the grading report in writing before you pay, and pay by a method that leaves a trail. Ask specifically what happens if the answer is no.
