1, let's fill a background color for our painted jewelry first. Here we choose the very common sapphire blue as the background color, and metallic yellow as the background color of inlaid jewelry metal.

2. Determine the details of light and shadow description. First, determine a light source for the jewelry, as shown in the figure below, and give the jewelry a light in the upper left corner. Then, create a new layer to draw the light receiving surface of the jewelry. Remember that even the light-receiving surface has a volume, so you can't paint the light too flat, so the jewelry will have no sense of volume.

3. Draw a shadow, continue to create a new layer, and then draw a shadow. There is one thing that needs our attention. Whether the metal has how bright or not, the shadow on the metal will be curved and sometimes very dark. We will find this rule and draw shadows slowly.

4, brightening, this step is relatively simple, we began to add some reflected light and refracted light to the jewelry. First, create a new layer, and change the mixing mode of the layer to light dimming or add light to draw the main reflected light. Then, draw the highlights on the jewelry in white on the side of the light source.

Precautions:

1. Clear lines: The lines in jewelry design drawings should be clear and concise, which can accurately express the designer's intentions and concepts. At the same time, the thickness, straightness and direction of lines also need to be selected and adjusted according to the design requirements.

2. Color matching: Colors in jewelry design drawings are also very important. Different color combinations can express different emotions and styles. Therefore, designers need to make reasonable color matching according to the requirements of jewelry materials, styles and colors.

3. Conforming to specifications: Jewelry design drawings need to conform to certain specifications and standards, such as the proportion, labeling and font of drawings need to conform to industry practices and specifications. This can ensure the accuracy and readability of the design drawings.
