Shreve, Crump & Low

Here today, here a decade ago, here when (odds are) you were still a glint in Daddy's eye—Shreve's diamond counter is one institution that has stood the test of time, and flawlessly. Quiz the professional, enthusiastic staff on the finer points of purchasing diamonds (we put them through the wringer for more than 45 minutes) and peruse the varied selection, from solitaires to princess-cut stones. Browse or buy to your heart's content; the stones and service are rock-solid.
