Doug, Well, if you stuck purely in the area you're mentioning, you'd
be missing pretty much all of Jeweler's Row, which is on 45 - 48th
Sts between Broadway and 5th.
There are many high-rise buildings throughout the district and the
wholesalers are located on all the floors, so you can't really just
wander around and stumble onto one all that easily.
Depending on what you're looking for, a stop at Metalliferous (34
West 46th st) would be in order, as they have significant
quantity-purchase discounts on ready-made silver jewelry, chains,
earrings, necklaces, neckwires, rings, etc. They do NOT have pieces
set with stones, though they have been very willing to help recommend
suppliers in their area for specific things I've looked for.
When exiting Metalliferous, if you head to your left a few stores,
you'll find Kenneth Singh and 46th St. Jewelry Supply (a fellow
Orchidian), with tools and displays. Great place to visit!
Exiting Metalliferous, if you head to your right a few stores,
you'll find an excellent oriental jewelry supplier whose name I can't
recall. However, they are wholesale to the trade with set pieces
featuring coral and other semiprecious materials -- really nice
things. They also have unset coral and such.
Dikra Gem at 46 West 45th St, 10th floor, is a wholesaler of
semiprecious stones and has excellent materials at great prices, with
friendly service (great combination!). If you're looking only for
ready-made, they don't have any, though.
I'm pretty sure that any of the above-mentioned merchants will
happily point you to others they know who are reputable and would
have more in line with what you're looking for.
