DEROSA JEWELRY

1934 to mid-1950s New York City

Let me begin by confessing that I am a big fan of DeRosa jewelry. It’s been one of my top favorites for almost 30 years, so
let me know if you have any for sale. I will always pay really fair
prices for pieces that I like.

Ralph DeRosa jewelry is known for its intricate and layered designs,
high quality, unusual stones and translucent enameling. Some of their
jewelry lines were designed by Elvira but I do not know who designed the
rest. Mr. DeRosa’s wife was Virginia De Rosa and she and their
two daughters, Teresa and Vera (Elvira), also participated in the company.
According the Deanna Cera’s book "Amazing Gems" on page 142, Fred Block
Inc may have manufactured some jewelry for DeRosa, too, but not everyone
agrees with that statement. Cera dates it from
1935-1955. DeRosa
jewelry designs include floral, figural, and retro motifs, as well as designs inspired by
some of the precious jewelry of past eras.

DeRosa jewelry is not easy to find because not many of each design were
made, but is certainly more than worth the search. After years of
collecting and selling this wonderful brand, I have found that the
majority of their pieces were signed, so beware unsigned attributions
unless there is reference material to substantiate it. This firm was
at 404 Fourth Street in New York City and created jewelry from the
mid-1930s until the mid-1950s.

As a serious collector, one of the best things about this company is
that not many of each piece was made. Many of the pieces shown below are the
only ones I have seen of their kind in all the years I’ve been handling
vintage jewelry. One exception is the cupid riding on a pearlized cloud
brooch, which I see very often. An example of it is shown here on this
page. To me, that and their brooches using tumbled uncut stones are much less interesting than the other DeRosa
pieces, and my guess is that they were made later.

Hand painted illustrations from the De Rosa Jewelry Company
seem to have been the first step in the design process. These miniature
works of art are from a collection of over 250 similar illustrations
that I am happy to own and use as a reference. Several are dated in the
1940’s, and many have hand written notes about how each piece should be
produced. Many jewelry designers never
worked on paper first, but for those who did, these illustrations are
illuminating as to the thought process and
design sense that went into creating this amazing jewelry.

We BUY, collect and sell DeRosa jewelry!

DeROSA and HOBE
Look-a-likes


Very rarely I run across a DeRosa piece that is made exactly like the Hobe
jewelry of the 1940’s, and the pieces here are examples. They are made just
like a Hobe bracelet or clip, but they are clearly signed "DeRosa". As far as I
know, there was no connection between these two companies, but these are SO
similar that it does make me wonder. I wish I knew for sure, and if you
do, please email and let me know.



DEROSA
bracelet in the 1940s Hobe style with unfoiled
rhinestones in green, golden and pale yellow set in silver wire work
and filigree, 6-3/4" by 2" wide at the front and 1/2" wide at the
back, circa 1940s. Hinged links make this flexible to wrap around the
wrist comfortably, and it is in very good vintage condition with no
missing stones and no damage or repairs. This is signed "DeRosa"
on the back.

DEROSA and HOBE bracelet
clasps. While these are both on typically Hobe looking
bracelets, the top one is
signed "DeRosa" and the bottom "Hobe". I wish I still had a shot of
the front of this DeRosa bracelet, but I sold it decades ago. The similarity is amazing and yet there is no
documented connection I am aware of between Hobe and DeRosa.

DEROSA
earrings with blue and green rhinestones surrounded by clear
rhinestones in a gold plated sterling silver setting, 1-1/8". Made
in the 1940s, they are reminiscent of Hobe jewelry but the findings on
these earrings are those used by DeRosa. The patent number on the
findings is "1967965", granted to Ballou & Company in 1934. Ballou
made all kinds of findings and I am would think that other jewelry companies used these
earring
findings as well, but so far I have not seen them on Hobe earrings.
NOTE: I have now seen a Sandor bracelet that has a similar gold plated
S-shaped element like these on the centers of the earrings. Just goes to
show that it can be a challenge to attribute unsigned jewelry to a
particular maker.

DeROSA, Deja and Reinad




DEROSA
lavender and green enameled tulip flower dress clip with artificial pearl
stamen and clear rhinestone accents, circa 1940, it is 2-1/2" by
2-1/8". Fabulous translucent enameling, so typical of DeRosa
jewelry, enhances this
three-dimensional piece.

Also shown
is the
DEROSA original design art work which
would have been done for approval before this clip was put into production, a
gouache on tissue which is itself a rare one-of-a-kind piece. As you can see, a few
minor changes were made in the final design when it was produced.

It is a
gouache or watercolor on tissue paper and is itself a rare one-of-a-kind

Art work #202

DEROSA
tulip flower brooch with faceted red glass beads centered with clear
rhinestones and clear rhinestone petal and leaf tips all in a gold plated setting, 2-3/4" by
2-1/8". It is also a bit similar to Coro patent 140,016 dated 1945,
but Coro did copy other jewelry makers. An almost illegible
mark on the back says something like, "F_ _ RS".

Much to my surprise, I found the signed Deja tulip flower fur clip at
the right, which is like the ones above except that one
of those is by DeRosa and the other has an illegible signature. Was
there a connection between DeRosa and Deja I wonder?

That reminds me of
the flower fur clips in the row below, which came in at least three
colors, one signed DeRosa,
one signed Reinad and one not signed at all.


https://www.morninggloryantiques.com/imagesDG/DeRosa/deja42397.jpg

DeRosa was made in New York City from 1934 to about 1970.

Deja was only made for only a few years between
1939 and 1941, and then, due to a patent dispute with another jewelry
company, the name was changed to Reja.

Reinad was made from the 1920s to the 1950s, and they were known for
copying the designs of other jewelry companies. They were also based in New
York City.

While the tulip fur clip is the same basic
design, it was decorated in different ways by each maker.

DEJA
tulip flower fur clip with lovely aqua faceted glass beads, each with a clear
rhinestone in the center and with each portion lined with clear rhinestones as
well for extra brilliance. It is all set in gold plated silver and signed
on the back "Deja", made in about 1940, 3" by 2". We have in our
collection the DeRosa design art work for a very similar
flower, shown

HERE
, and find it interesting that they were offered by at least two
different companies, Deja and DeRosa.

REINAD
flower brooch with multiple layers in bright blue and clear
rhinestones, the first layers of a rose gold plate and the others of yellow
gold. This is signed "Reinad" on the back in tiny difficult to read
letters, but the signature is there. It is 4" by 3" and does have some
light finish wear on close examination. I have seen this same clip
with the DeRosa signature, and also some not signed at all.

DeROSA REFRESHED


Occasionally, we have a lovely DeRosa piece refreshed with new enamel work. We
send it to an excellent professional enamellist to have this work done, and the
two pieces shown here are examples of beautiful results.

Since plating can sometimes show signs of wear as it ages over many years, this is a nice way to extend
the wearable life of the piece. I will always state
in my descriptions if I have had my pieces enameled again.

DEROSA
large gold plated feather brooch with wonderful enamel work in aqua, pale
yellow and pink with clear rhinestones, 4" long and made in about 1940.
It is signed at the on the back at the very bottom of the stem, and the
enamel work has been professionally done this year (2023). Because the
gold finish was a tad rough, we though the enamel would add a lot to this
marvelous brooch, and it has, even though it is not original to the
piece. The last photo shows how it originally looked when it came
to me.

The masterful detail in the enamel work on this piece, with tiny lines
accenting each element, shows a skillful professional hand. The
finish was a bit rough when this came to me, so rather than not being
able to wear it. I had it professionally enameled and the result is amazing!
It is signed on the back "R DeRosa" and was made in the 1940s.

DeROSA for REFERENCE

Every once in awhile I see a wonderful piece of DeRosa
jewelry that has issues that cannot be repaired. The
clips on the right and left are good examples. I want to share
them here so their lovely designs can be seen by others, and hopefully I will find them in good
condition one day!

DEROSA
red enameled lily flower fur clip with the back flower petal
missing, 4" by 2-1/4". It is signed "R DeRosa" on the back.
While the photo may look upside-down, the clips on the back show that it
was meant to be worn like this. I am always sad to see a wonderful
piece of DeRosa that is broken like this one, but I have worn it as it is and no one noticed the
missing petal.

We are always looking for DeRosa
jewelry to buy, and because I collect as well as sell it, I pay very
good prices for the pieces I want. Please do

DEROSA fur clip, as is with one stem missing,
it has a large purple marquis shaped center rhinestone, 3 shocking pink long
stones and clear rhinestone accents, along with green enameled leaves.
Sadly,
it’s missing one stem at the bottom where there should be three stems. It is 4-1/3" by 1-5/8" and signed "R

DeROSA given new life!

Restoring vintage jewelry seems to
have gotten a bad name, but I think it is because such restorations are
often not disclosed to the buyer. When a piece of jewelry comes to me
with wonderful design and underlying quality, but with finish damage or
other issues that can be repaired, I am happy to have it professionally
restored and given a new life! I definitely think that it should
be disclosed to the buyer in my descriptions, though, so that the buyer
can decide for themselves how they feel about it.

Here is a good example.

DEROSA
intricate pink enamel flower bouquet fur clip with unfoiled topaz
colored marquis and oval center stones with
lots of clear rhinestones, some that have turned gray over the years,
and lovely enameled green leaves,
4-1/3" by 2-1/4". There is a bow at the top with rhinestones and pink
enameling. NOTE: This came to me with worn enamel, so I had it
professionally enameled again in 2020.
The colors were chosen based on the original design art work in my
collection, seen here at the right. The rhinestones are brilliant,
the gold plated finish is in very good vintage condition and the clip is
tight and works well. From the 1940s, it’s another wonderful design from
this amazing jewelry maker, and it is signed on the back "R DeRosa".

The wonderful DeRosa fur clip shown at the left came with finish damage, and since
I thought the design and quality of materials were well worth it, I had a
professional enamelist restore it.

The results will allow this beautiful piece to be worn and enjoyed for many more
years to come.

It has no signature so I cannot be certain that this is a DeRosa clip, but
it sure has the earmarks of either their work or a of a Dujay fur clip.

there were also graying rhinestones. The original DeRosa design art work
