Step-by-Step: How to Choose the Perfect Solitaire Diamond Ring

1. Decide on the Diamond Shape

The shape is the first impression. Round is classic, but there are many unique options:

• Round Brilliant: Most popular, known for its incredible sparkle.
  
  

• Princess Cut: Square shape with sharp edges, modern and bold.
  
  

• Oval Cut: Elegant and elongating on the finger.
  
  

• Emerald Cut: Vintage and refined with step-cut facets.

2. Focus on the 4Cs

Understanding the 4Cs will help you make an informed decision:

• Cut: Affects how much the diamond sparkles.
  
  

• Colour: Ranges from colourless (D) to light yellow (Z). Near-colourless (G-H) is a great balance.
  
  

• Clarity: Refers to inclusions. SI1 or VS2 clarity can offer great value.
  
  

• Carat: The weight (and size) of the diamond. Choose based on your style and budget.
  
  

3. Choose the Metal Type

The metal of your ring can enhance the beauty of your diamond.

• White Gold: Classic and elegant.
  
  

• Yellow Gold: Warm and vintage-inspired.
  
  

• Rose Gold: Romantic and trendy.
  
  

• Platinum: Durable and luxurious.
  
  

4. Select the Perfect Setting

The setting holds the diamond and affects how it catches light.

• Prong Setting: Maximises light exposure for brilliance.
  
  

• Bezel Setting: Modern and secure, ideal for active lifestyles.
  
  

• Tiffany-Style: Signature solitaire look with six prongs.
