Pearl Inlay on Martin Guitars
The first Stauffer influenced Martins had a pearl pattern set in mastic on

This pattern was soon combined with these "moons" on the rosette.
The first pearl on the top border are semi-circles which are thought
to be made from button blanks.
1837 Martin Hudson Street Guitar
In the 1840's we begin to see tiny diamonds in the rosette.
Approximately 11 examples of early Martins with pearl diamond rosettes are
known to exist today, all of which follow one of three basic patterns.
The simplest pearl diamond rosette pattern consists of a three ring
rosette with a single strip of diamonds in the center ring.
1840's Alternate X Brace Spanish Style Martin
This jewel-like example has an unusual top border made of pearl diamonds
in addition to the second variation of the diamond rosette, with an early
use of solid pearl rings comprised of smaller blocks of pearl, surrounded
by two rings of pearl diamonds.

The third style of pearl diamond rosette follows the form of a traditional
Martin three ring rosette with the center ring consisting of a 5 plies of
ebony and ivory rings surrounded by two rows of pearl diamonds.

This example also has marquetry on the sides adjacent to the ivory
This unusual example of an early version of a Martin guitar in the Style
30+ range, with a pyramid bridge with pearl pendant, fancy side filets,
ebonized neck with ice cream cone heel, spruce lining, and a mature X
brace, has a unique pearl rosette which may be the earliest variation of a
solid band of pearl replacing the rows of tiny diamonds.
Martins first fancy pearl fingerboard and headstock inlays
were on their mandolins.
Martin Style 5 Mandolin, 1899
The binding of the Style 5 mandolin is made of alternating blocks of
genuine tortoise and pearl.
Martins mandolins featured heavily inlaid real tortoise pickguards.
From the beginning of Martin's established models in the 1850's until
1902, the Style 42 was the most embellished guitar in the Martin line.
It was richly inlaid with pearl on all top borders, including the
soundhole and the borders of the fretboard extension.
Martin Style 42
Until close to the turn of the century, no guitar in the Martin product
line, including the Style 42, had pearl or other adornment on the
fingerboard, or on the headstock.
The first Martins to have pearl inlays on the fingerboard appeared in
approximately 1896, with "Snowflake" inlays on three frets of the fancier
These early inlays have a delightful folk art appearance.
1896 Martin 2-42
A fourth inlay was added the following year...
While small white dots appear on the side of fingerboard consistently by
1917, some Martins from the mid 1840's have large abalone dots not on the
fingerboard, but on the side of the cedar neck itself.
The Style 45 DeLuxe is the first and only production Martin guitar to have
inlays on the pickguard.
1930 Martin OM-45 DeLuxe
Serial # 44070
The OM-45 DeLuxe is also the only catalogued Martin ever offered with an
inlaid bridge, though these were common on many Chicago guitars.
The early Hudson Street Martin is one of a number of early Martins to have
decorative ivory and pearl pendants affixed to their pyramid bridges.
The pendants are seen on Martins as late as the 1850's, as on the 1850's
Martin with the interesting early pearl rosette:
It's often said these days that Martin is a conservative company, who's
instruments lack the glitz of many other makers. You can see by the
instruments above that Martin's roots include some pretty fancy
This 00-42S with a custom pearl fingerboard was special ordered in 1905.
The Style 40 Martin was similar to the 42 with the except for the lack of
pearl inlay surrounding the fretboard extension.
This early Style was revived in the 1920's for the 00-40H, a Hawaiian
version of Martin's 12 fret 00.
1934 Martin 00-40H
The Style 27 was the least expensive pearl inlayed Martin, with pearl on
the rosette only.
The Style 30 also has a pearl inlayed rosette. Here you can see a
Style 27 with a Style 30, which appear to be nearly identical. In
fact, in some years, the only difference between the style 27 and 30 were
the tuners, which were brass on the Style 27, and silver plated on the
The Style 34 was similar to a style 30, with pearl rosette, but with the
addition of an ivory bridge.
Here's a more unusual Style 34, with a unique wider band of pearl that
we've never seen on another Martin.
In 1902, Martin was said to have built three custom ordered Style 42
guitars, labeled 00-42S, which were adorned with pearl on the back and
sides in addition to the top. This style guitar with added pearl
trim was later adopted formally into the Martin product line, and called
the Style 45. Martin actually built two guitars with the same serial
number, so four guitar were produced with added trim in 1902, three of
which had a fancy tree of life inlay on the fretboard, and one of which
had snowflake inlays closer to what would be seen on the production Style
1902 Martin 00-42S
Martin later added inlays to two additional frets.
Style 45, 1919, with inlays added at the third and 17th frets.
The Style E, designed for guitar teacher William Foden, is unique in
having pearl on the top border with no pearl surrounding the fretboard
extension, like a Style 40, yet having pearl on the borders of the back
and sides, like a Martin Style 45.

The Style 45 also has beautifully mitered pearl inlays on
the borders of the back and sides and surrounding the end piece and the
Pearl on Martin Guitar Headstocks
The Style 43 Martin never had inlays on the headstock. The first
style 45 Martins appeared in 1902 as custom versions of the Style 42, and
included a "fern" inlay on the headstock.
The version of the fern appearing on the first Style 45 prototype was used
for several years. This custom ordered Style 42 from 1902 was one of
two to have this particular "fern" style headstock inlay, which in recent
years has been copied and made available on certain custom Martin
guitars as the "alternate torch"
1902 Martin 00-42S
The "fern" inlay was replaced on Martin Style 45 guitars by what has
become known as the "torch" or "flower pot".
1919 Martin 0-45
This first torch was replaced on Martin Style 45 guitars by a second
somewhat simplified version of the "torch" or "flower pot", which was
designed for the solid headstock on the 14 fret OM.
1930 Martin OM-45 DeLuxe
In 1931 the pearl "MARTIN" headstock logo first appeared on this
first Martin archtop prototype:
1931 Martin C-1 Prototype:
In 1932, a "C" and "F" were added to the logo, and the serifs were
This logo was then used on the solid headstock Style 45 Martins starting
in 1934 while the slotted headstock Style 45 continued to use the torch.

I'm thrilled to include comments from the acknowledged expert on the
sibject, "Chainsaw" Chuck Erikson, The Duke of Pearl:
"Beautifully done instruments, thanks for the pics! As for using different
types of shell, all those shown contain only 2 types: white Australian MOP
and California Green ab. But then as now inlayists knew how to sort
abalone blanks into various subgrades depending on figure and hue such as
(in modern terminology) "standard color", "select color", "heart", "pale",
"rippled", and others.
Most are subjective visual distinctions, but a couple of them are related
to shell age and anatomy. "Heart" is the usually very dark and densely
burly material found in the central "muscle scar" area of most abalone (a
univalve, or snail), where the animal is attached to the shell. This layer
is often only on the surface, so preserving it is a problem and the
smaller shells now commercially available yield only small (and very
expensive) quantities. The 7th fret on the solid shell fingerboard
pictured above is a beautiful piece of heart.
In Green abalone (Haliotis fulgens), and to a lesser degree in the Pink
abalone (H. corrugata), the washboard-like ridges on the shell produce a
wavy "rippled" figure in the underlying nacre. In material from the Green
ab., this figure can be very tightly structured (much like fiddle back
maple). In selecting for top-quality "rippled" the pieces need to have
very well-defined and closely-spaced ripples which penetrate through most
of the blank's thickness (so it won't sand away), must be totally pale
with no intrusion of darker colors, should have either no or very minimal
black lines running through it, and be free of any small boring sponge
holes, inclusions, cracks, or other visible defects. The best ripple comes
from the smallest and youngest shells which usually yield the least
intense colors (as an abalone gets bigger the ripple becomes less distinct
but the shell colors become darker and much more intense). The 1837 guitar
uses rippled in the paler half circle edge trim inlays.
Some of the darker pieces having closely spaced lines (as in the mandolin
pickguard, the 9th fret on the solid shell fingerboard, and the slotted
peghead) come from older shells which contain dense color layers (and
almost no ripple). A variation of this would be the circular "bull's eye"
figure usually taken from the heavily domed area of a shell from which the
animal spirals as it grows. Very straight lines of dark colored layers are
referred to as "striped".
As for the white MOP, the two main distinctions (and there are many
sub-grades) are "plain" and "figured". Plain Mop is preferred for thin,
delicate designs such as script logos, vines, and the small diamonds and
snowflake inlays in the above instruments. MOP containing much figure
would interfere with the visual clarity of these smaller elements, making
their shapes/outlines harder to see. But larger pieces as in the solid
shell fingerboard are a great place for showing off the more interesting
figured material without interfering with how a design "reads" to a
viewer. Plain material comes from the flatter outer "lip" of ocean pearl
oyster shells (Pinctada maxima, a bivalve), while figure is generally
associated with the animal's muscle scar area and next to the heavy
"notch" at the top of the shell's hinged edge.
More than you wanted to know?"
