How do I choose a loose diamond?
This is where many buyers get overwhelmed.You start reading about clarity, colour, carat weight and cut, and suddenly every diamond looks the same.
Focus on the famous "4 Cs":
Cut
The cut determines how well a diamond reflects light.
Colour
Diamonds are graded from colourless to light yellow or brown. Higher grades typically command higher prices.
Clarity
This measures natural inclusions within the stone.
Carat
Carat refers to weight, not visual size alone.
Here's something many experts won't emphasise enough: a slightly smaller diamond with an exceptional cut can look more impressive than a larger stone with poor light performance.
Funny how that works.

Because it maximises sparkle better than almost any other shape.
