**Diameter**: the distance from one side to the other, passing through the centre

**Radius**: the distance from the centre to any point on the circle

## Lets Begin

Here is going to show if you did well in Geometry at School

**Step 1**

Always start with finding the centre of your paper, then draw a circle with the compass with the size of the circle you require.

For easier to remember and calculate, let's say the circle is 10cm Diameter (5cm radius - from the centre point to the edge of the circle)

**Step 2**

After completing the circle, divide it to 16 triangles like so bellow using a Protractor

Separate the circle to 4 sections - 90 Degrees each

Separate it again, now 45 Degrees each

And again, now 22.5 Degrees (In between each 45 Degree triangle)

It loos very complicating but ones you've done it it will get easier for the next time

**Step 3**

Draw a centre circle 60% smaller than the main one.

Example:

If you did a 10cm first circle which is a 5cm radius, the inner circle must be a 6cm diameter or 3cm radius.

Diameter - 60% = Diameter

## 10cm - 60% = 6cm

7cm - 60% = 2.8cm

5cm - 60% = 2cm

3cm - 60% = 1.2cm

so you have to measure 3cm opening on the compass

**Step 4**

Draw 2 squares like shown on the picture using the 90 Degree Ruler and just touching the inner circle with the lines.

**Step 5**

From the edges of the squares, draw a line horizontal towards the edge of the circle like shown on the image to form the Bezel Facets

**Step 6**

**Now is the fun part**

Grab your eraser and erase the straight lines we drew on Step 2, leaving the lines that are on the edge of the squares

(The Upper Half Facets)

**Step 7**

The final part is to erase the circle we drew at Step 3

**And We are Done!**

You can now draw a Round Brilliant Cut Diamond.
