rendering jewelry with watercolor can be very simple hi I'm PJ Chen I have taught jewelry design for over 14 years in college
I'm going to show you step by step process of rendering a cabochon gemstone today in this tutorial
let's get started
let's talk about what material do we need in this tutorial
I am using bristol pad. it doesn't matter what brand it is as long as the bristol pad
and there is smooth surface
For the water color I'm using Windsor Newton Cottman watercolor sketch pocket box
it comes with 14 different color
you also need opaque white. I pick Copic opaque white it works really nice
and smooth let's take a look on the brush there are several brush you can
use they you can use Princeton Art and Brush #6
you can also use Windsor Newton Cotmen round #6 or #8
and this is my favorite brush this is a Windsor Newton finest sable #1 for highlight
in this tutorial I use a lot of a Chinese calligraphy brush you don't need all the
brushes for this tutorial this is just the option for you. you also need automatic
pencil and eraser for starting the sketch. let's take a look on the
construction for oval cabochon stone we're going to assume the light is
coming from the left top corner the darkest area will close where the lights
coming from so it will be on the left top corner of the cabochons on the right
bottom corner because it's transparent so you're gonna see the reflection from
the ground where I draw a circle it's going to be highlight or call hot spot
sometimes I like to put a dot on the right bottom corner just personal preference
let's take a look on the structure of the ring I'm going to
sketch it really quick it may not be completely corrected on the perspective
but just want to tell you where I'm going to put the what color so I have a
dome ring here inside is flat so we are going to giving a graduation
both sides are going to be darker. on the bottom of the ring shank the lower part it's going to
be dark so we're gonna put those brownish color and then the darkest part
is going to put a very dark brown color to show in the high contract inside of a
ring shank we're going to do the gradient from the dark which is like
dark brown color to the light which is high light white color and also we going
to blend it back to the dark so that was showing for the inside of the ring shank
the rest of the ring shank will be yellow color right there I will put a little
bit dark brown color same as the one on the bottom and we are going to use the
structure from the cabochon just put it right there on the ring so here's it is
I'm going to speed it up three times to show you how I draw this one
