Buying a diamond is an exciting experience, but with so many options available, choosing the right one can feel overwhelming. From selecting the perfect shape to understanding carat weight, color, clarity, and certification, every detail plays a role in finding the ideal diamond.
At Solitairekart, we offer a premium collection of IGI Certified Lab Grown Diamonds that combine exceptional brilliance, quality, and value. Whether you're designing an engagement ring, pendant, earrings, bracelet, or custom jewelry, this guide will help you make an informed decision.
Why Choose Lab Grown Diamonds?
Lab Grown Diamonds are real diamonds with the same physical, chemical, and optical properties as mined diamonds. They offer identical sparkle and durability while providing a modern, sustainable, and affordable alternative.
Every Lab Grown Diamond at Solitairekart is carefully selected for quality, ensuring you receive a beautiful diamond you'll cherish for years.
Explore Different Diamond Shapes
The shape of a diamond defines its overall personality and style.

The most popular choice, loved for its unmatched sparkle and timeless elegance.

A graceful teardrop shape that offers a unique and sophisticated appearance.

Choosing the Right Carat Weight
Carat refers to the weight of a diamond—not its sparkle.
The ideal carat depends on your personal style and budget.
Popular options include:
- 0.25 Carat – Elegant everyday jewelry
- 0.50 Carat – Classic and versatile
- 1.00 Carat – The most popular engagement ring size
- 2.00 Carat & Above – Bold luxury and statement jewelry
The right cut and shape can often make a diamond appear even larger than its actual carat weight.
Understanding Diamond Color
Color is one of the most important factors when selecting a diamond.
At Solitairekart, we offer premium color grades including:
DEF Color
Colorless diamonds with exceptional brightness and premium brilliance. Perfect for luxury engagement rings and fine jewelry.
GHI Color
Near-colorless diamonds that provide outstanding beauty while offering excellent value.
Both categories look stunning, and the best choice depends on your preference and budget.
Understanding Diamond Clarity
Clarity measures the natural inclusions inside a diamond.
We offer high-quality clarity grades, including:
VS1 – VS2
Very Slightly Included diamonds offer exceptional beauty with inclusions that are difficult to notice.
VVS1 – VVS2
Very Very Slightly Included diamonds are among the finest clarity grades, offering remarkable purity and brilliance.
These clarity options are ideal for engagement rings, bridal jewelry, and custom diamond creations.
