Although it appears
to be 2 pieces of black jade it is actually one large piece. The 2 princess cut diamonds
(each over 1 ct.) are held in place by bezels black jade. A trough has been cut into the
black jade as well as grooves into the sides of that trough for the girdles of the
diamonds to slide into. Two holes have been drilled through the black jade under the
diamonds for cleaning. You will also notice on the other end of the ring a large
dished-out area with 3 14kt gold rods which give the illusion that the black jade is held
in place with the rods. After the jade has been fit to the ring, the diamonds are slid
into place as well as the 3 gold rods. The piece of black jade is then lowered into the
"U" shaped opening in the ring and seated in place where it is held with epoxy.
The ring is size 18.

The Lapis for these earrings were cut to make them protrude from the ends of the
gold work.

The designer of this piece provided us with wax carvings to show us how they wanted the pieces of Black Jade shaped. There are 5 separate pieces of carved Black Jade. The center piece is pear-shaped like the center Emerald. The Emerald is mounted in a pear-shaped gold mounting and sleeve which inserts into a pear-shaped hole cut into the Black Jade. The two far outside pieces have a series of ribs carved into them. On each side of the center piece are pieces of Black Jade which overlap both the center piece and the outer pieces. The goldsmith designed an elaborate hinging mechanism that attaches to the back of each piece of Jade. This connects all 5 pieces and allows them to articulate and move beside one another while the neck piece is being worn and gives to look of one large “flexible” piece of Black Jade. The designer of this piece is truly a creative genius.

The customer that
this ring was designed for wanted a ring with 12 tapered black onyx baguettes which meet
at the bottom under a large center mounted diamond. Mounting so many tapered black onyx
baguettes can be very problematic for a setter to say the least. The appearance of the
finished product is also a concern. I proposed cutting black jade to fill in the area
around and under the center diamond. I would cut grooves into the black jade which would
give the illusion that there were actually several separate stones. The grooves could only
be cut if the black jade were in 2 pieces and later joined together. Step 1) The first photo shows the 2 pieces of black jade glued
together so that it could be carved to fit into the opening in the ring.
Step 2) The second photo shows the 2 pieces of black jade
which are now separated and now have the grooves carved into them to make them look like
several stones joined together.
Step 3) The third photo shows the 3 parts ready to be
assembled. The engineering jeweler designed the ring with a threaded post on the bottom of
the head with the diamond in it.
Step 4) The fourth photo shows the ring with the 2 pieces
of black jade in place.
Step 5) The fifth photo shows the fully assembled ring with
the diamond screwed into place.
I was told that the retail customer was delighted with the
final result. It had the look of 12 separate tapered black stones that she wanted and
without so many prongs to hold them in place. The black jade also gave them more
durability than onyx would give her.

The jeweler provided
me with a wax carving to illustrate how he wanted the ribs to be carved and shaped into
the mother-of-pearl. The mother-of-pearl also needed a pear shaped recessed area cut into it
for the pear shaped bezel with ruby to fit into it. Although
the mother-of-pearl in the photo appears to be yellowish, this is due to the lighting that
was used during the photography. The mother-of-pearl was actually white.
The bottom photo
shows the fully assembled piece.

When the goldsmith sent me this ring the square tube with the square diamond was
already soldered in place. The inlay needed to be cut to fit, with a square hole in the
stone, so that it "dropped down" and over the center square diamond and fit tightly in the
ring. This is a very time-consuming process to get the stone to fit tightly without any glue
showing around the edges. I enjoy the challenge.
This ring is also a good example of the use of unique materials. This jewelry designer is located in the Pacific Northwest near the Columbia River. The Columbia river banks are
lined with native rock of various colors with beautiful patterns that show up when they are
wet, or when the rocks are polished. The rock that is inlaid in this ring is from the banks of
the Columbia River. It is popular with his local customers to have a ring that is inlaid with
this local material. This ring was designed by Michael Nutter.

This ring had originally been made with the piece of white quartz which is in the upper right part of the picture. The customer wanted to replace it with Black Onyx. A gold arch was already soldered in the ring, therefore the only way to put the Onyx in the ring was to make two separate pieces and insert them from the sides. You will also see holes drilled through the pieces of Onyx from side to side. These are for a gold pin that will hold the pieces of Onyx in place and have diamonds mounted in the ends.

Although it appears to be two separate pieces of Lapis it is actually one piece. A “U” shape channel was carved into the Lapis and grooves were cut into that channel to accommodate the girdles of the diamonds. A dished out area is also carved into the Lapis and three holes are drilled from side to side to accept the three 14kt gold rods. Once the piece of Lapis was properly fitted into the ring, the diamonds are inserted into the channel and the three gold rods are also inserted in place. The Lapis with the diamonds and rods is then
epoxied into place and the top is given a high polish to finish the piece.
This piece was designed by the same goldsmith who designed the Black Jade piece at the top of this page.

This matching set of cufflinks and tux studs was made from Black Jade. The sides of the Black Jade have curved areas carved into them. The diamonds are able to slide in the channels that have been cut into the Black Jade.

This ring is similar to the previous ring but in this case two pieces of Lapis in inlaid separately. The pieces of Lapis are butted up against the Diamond and small bevels are polished on the Lapis where they meet the Diamond.

This is an onyx
stone which has had a diamond set into it without the use of a gold tube or bezel. The
diamond is inserted from the back of the onyx and held in place with a bezel of onyx
so-to-speak. The diamond is held in place with a section of 14kt gold tubing which is also
inserted from the back. This also allows the diamond to be cleaned.

This is a pair of earrings with matching red
rubellite cabs mounted in the center of each. The bezels with the cabs are inset into
quartz which has been carved and left with a frosted surface. This was simply a matter of
duplicating the original.
