how to draw a 3d diamond shape

Drawing a diamond may seem intimidating—any pattern of this gem is extremely complex. The practiced news is that in that location is a potent logic behind the system of the diamond's facets.

Mined rough diamonds are converted into gems through a multi-step process called "cutting". This procedure is traditionally considered equally a delicate process that requires skills, special tools, scientific cognition, and experience. The final goal is to produce a faceted jewel where the specific angles between the facets optimize the dispersion of white calorie-free.

A diamond cut is a style or design guide used when shaping a diamond for polishing; this notion refers to the symmetry, proportioning and shine of a diamond.

In this tutorial, we'll explore and stylize the well-nigh popular style—a round cut diamond—in two dissimilar foreshortenings.

What You Will Need

You will need the post-obit equipment to complete this projection:

  • a graphite pencil (I recommend using an HB or H blazon)
  • a pair of compasses
  • a protractor
  • a ruler
  • an eraser
  • an ink pen (an optional tool)
  • drawing paper

1. How to Describe a Diamond in a Top View

Footstep 1

I marker a signal; let's agree that its proper name will be the betoken O.

I apply it every bit a central point to depict a circle of an arbitrary radius. A pair of compasses is a neat tool for creating an even circumference.

Step 2

I draw two perpendicular dashed lines going through the key point.

Pace 3

I carve up each sector of the circumvolve in half. An like shooting fish in a barrel way to do it is to find the angles of 45°, using the protractor. Now we have eight points of intersection with the circumference.

I also mark the points A and B to brand farther explanations visually clear.

I connect the points A and B with a dashed line, using a ruler.

Pace iv

I draw a perpendicular line going from the center of the circumvolve to the AB segment, and then extend the line in the opposite direction.

The point D marks the place where this line meets the circumference.

Step 5

I join the points of intersection with a dashed line to create an octagon.

I divide the sectors of the circle in half in one case again.

Step 7

With a ruler, I mensurate the length of the OB segment, and and then observe its approximate one-fourth part and mark it with the bespeak C.

Delight note that this value may vary—sometimes diamonds of the same blueprint look different. Cutting a diamond is a scientific discipline, only it's also an art!

Marking a new point Marking a new point Marking a new point

Step 8

With the compasses, I measure out the length of the OC segment and add seven more points to other dashed lines, creating new segments of the same length equally the OC is.

Pace nine

I connect the points C and D.

Step eleven

I mark the point Due east; it is located at an arbitrary altitude from the circle's heart.

And so I measure the length of the OE segment and mark the new points that are equidistant from the centre.

Step 14

With an ink pen, I outline the shape of the diamond and erase the subsidiary pencil marks. The cartoon is complete!

2. How to Depict a Diamond in a Side View

Step 1

I describe a straight line, using a ruler. My line'south length is 10 cm—knowing the verbal value is beneficial for the next steps because we will exist making some measurements.

Please be sure to leave plenty infinite for the lower part of the diamond.

Step 2

I add some other straight line (the distance between the lines is v mm) and connect them. At present nosotros have a narrow, elongated rectangle—it's the typhoon shape for the diamond's girdle.

Stride iii

With a protractor, I find the 45° angles and describe 2 lines. They will intersect at some signal and create a basic shape of the diamond'southward pavilion.

The value of 45° is considered an ideal pavilion bending—it gives the best lite functioning, simply at that place are many examples that don't suit to the standard (deep or shallow variants).

Step 4

It'due south fourth dimension to construct the diamond's upper part, the crown. I discover the angles of 34° (again, this value may be different) and depict 2 diagonal lines of 2.5 cm each.

Footstep 5

I add a straight line to create the table of the diamond.

Pace vi

I depict a dashed line that divides the diamond in half. This will be our reference line to make sure that everything in the drawing is symmetrical.

Adding a reference line Adding a reference line Adding a reference line

Step seven

I create the subsegments inside the OA segment. The commencement three parts accept a length of approximately 1.vi cm, and the fourth office is very short.

I also give the names A, O, and B to the points of the shape to brand the demonstrations easier.

Adding the marks of the subsegments Adding the marks of the subsegments Adding the marks of the subsegments

Footstep viii

Let's agree that the starting point of the first subsegment of the girdle is the point C.

I connect the points B and C.

Adding a diagonal line Adding a diagonal line Adding a diagonal line

And then I bring together the points on the opposite side of the shape, as if I'g mirroring the design.

Footstep 9

I split up the CB segment into three approximately equal parts and mark the lower ane with the betoken D.

Step 10

I connect the points D and O. Then I bring together the betoken D with another point on the left side (it'south the point E in the analogy beneath).

Step 11

I reproduce this set of lines on the reverse side of the shape.

Reflecting the set of lines to the right side of the shape Reflecting the set of lines to the right side of the shape Reflecting the set of lines to the right side of the shape

Step 12

I add the bespeak F; information technology should be on the same imaginary line as the bespeak D or slightly lower than it. Then I connect the points E and F.

Footstep 14

I add together a short line to the bottom part of the diamond, equally if I'm cutting a small part of the shape. At present we have the culet of the diamond (the tiny point at the base of operations).

Pace fifteen

I split up the OA segment into seven parts and echo the same activity with the symmetrical correct half of the diamond.

Step sixteen

I depict a distinctive pattern that consists of wider and thinner parts. Actually, there is no strict rule for how a diamond girdle should look, so yous tin can be as creative as you wish.

I complete the girdle.

Pace 17

I depict a vertical dashed line from the point F and mark the point of intersection with the upper line with the letter H.

And so I add some other line, going from the corresponding point on the right side; now we get the bespeak H₁.

Step 19

I add a line going from the bespeak I to the prominence to a higher place the indicate E.

Then I reverberate this line to the contrary side of the drawing.

Pace 20

I add a line going from the point I to the prominence above the point G. Then, every bit usual, I repeat the design on the right side of the shape.

Step 22

I add the point O₁ where the vertical line from the point O intersects the girdle, and a point O₂—where this line meets the top border of the diamond.

Adding two derivative points Adding two derivative points Adding two derivative points

I connect the points O₁, H, and H₁.

Step 23

I draw diagonal lines from the point O₂. The line on the left side is directed to the bespeak E, but we don't need information technology and the corresponding line to cross the O₁H and O₁H₁ segments.

Adding two short lines Adding two short lines Adding two short lines

Footstep 24

In the previous step, nosotros got a small shape that resembles a rhombus; now I mark the side point of this shape with a letter J.

I draw a line that connects the point J with the prominence above the indicate Eastward.

Connecting the points Connecting the points Connecting the points

I repeat the same action on the opposite side of the diamond.

Step 26

I outline the contours of the facets with the ink pen and erase the pencil marks. The diamond is complete!
