# Create Main Gem
In this lesson, we are going to work with a 0.4 carat diamond. RhinoArtisan provides several methods to add gemstones to your design. Let’s explore the options available for selecting and positioning your diamond.
### **Using the Diamonds Tab**
* In the “Diamonds” tab **(1)**, select the “Gem Studio” command **(2)**. This will open a panel where you can customize various parameters of your diamond.
* Set the parameters according to your design needs. **(3)**
* **Add to Center (4):** The diamond will be added to the center of the viewport.
* **Add to a Specific Point (5):** Select a point in the viewport, and the diamond will be positioned at that exact location.
* **Add to a Surface Point (6):** Select a surface, and then click on specific points on that surface to position the diamond precisely.
### **QuickGems Panel**
The **QuickGems** **panel** is located on the left side of the interface. From here, you can quickly select the diamond’s shape, material, and choose from the available carat weights.\

Once selected **(1)**, the diamond will be automatically placed in the center of the viewport.
### **First Step: Add your Gem**
Use the method that you find most comfortable and add a half-carat gem to the center of the viewport, without any alignment, to begin the tutorial.
### **Display Mode**
Click on the bottom-right corner of the viewport and select *Shaded Display Mode* to improve the visualization of the model.
