Reading the info, it looks like they're taking standard 14K, and
doing a weird rhodium plate over it. So it's just a plate job, and
won't hold up to any kind of everyday wear.
(even says so.) Weird, but nothing especially new or neat.
I gotta say at least the page with the colored stuff was reasonably
open about it. to quote their page on one of the rings (a garish
unrealistic flourescent pink suggesting the CAD person had no idea
what the stuff actually looks like), :
This ring is a designer exclusive high-maintenance jewelry piece.
Pink gold (pink rhodium on 14k solid white gold) will wear off in
about one to two year of wearing making your ring look exquisite
vintage by exposing solid white gold base on the edges and flat
surfaces. Pink rhodium reapplication is not necessary, however if
desired, we provide two year (2 time) free pink rhodium
reapplication on all designer pink gold rings for all
ClassicEngagementRing customers. This service is available with
select jewelry manufacturers U.S. nationwide for a fee to
maintain pink rhodium color for your jewelry piece for continuous
wearing over it's lifetime"
They say right out front that it's High Maintenance. That particular
ring, all the stones, including the black diamonds, are all
synthetics. With the others, those that have diamond melee, the
diamonds are real enough, but everything else is synthetics (cheap.)
That other page also has a couple interesting notes. Again, all are
CAD renderings, not photos, as Brian notes. Here, All the stones are
cubic zircona, even the colored ones. No synthetic corundum here. And
they just call it "black gold", so could be black rhodium, or could
be that Legor ceramic coating that we were discussing a few days ago,
or something similar. I'd suggest the latter, because I note that a
fair number of the rings are not based on sterling silver under the
black, but are "titanium stainless steel". Not sure what alloy that
would be, but I'm guessing it's cheap...
The only other comment I'd have is to wonder.... Do people actually
buy this junk? (yeah, and I know the answer. a bit depressing. But a
good use of CAD at any rate. Put together an entire line of inventory
and put it on a web page where all you need to have done before,
aside from the computer time, is figured out which chinese factory
you'll contract with to produce the stuff for you and drop ship...
