Learn About Diamonds
Discover the Beauty Behind Every Diamond
A diamond is more than just a beautiful gemstone, it's a story billions of years in the making.
At Nyama, every diamond is thoughtfully selected for its brilliance, beauty, and craftsmanship, ensuring every piece is designed to be treasured for generations.
Whether you're purchasing your first diamond or creating a bespoke heirloom, we're here to make the journey simple, transparent, and enjoyable.
Natural & Lab-Grown Diamonds
Natural Diamonds
Natural diamonds are formed deep within the Earth over billions of years under immense heat and pressure. Their rarity, durability, and timeless beauty have made them enduring symbols of love and celebration.
At Nyama, we source our natural diamonds responsibly through trusted suppliers who follow internationally recognised ethical sourcing standards.
Lab-Grown Diamonds
Lab-grown diamonds are real diamonds created in advanced laboratories that replicate the natural diamond-growing process.
They possess the same chemical composition, crystal structure, hardness, brilliance, and fire as natural diamonds. The only difference is their origin.
Lab-grown diamonds offer the same beauty and durability while providing a more accessible option for those seeking larger sizes or higher quality within their budget.

Understanding Diamond Quality
Every diamond is evaluated using the internationally recognised 4Cs.
Cut
The most important factor influencing a diamond's brilliance.
A well-cut diamond reflects light beautifully, creating exceptional sparkle, fire, and scintillation.
At Nyama, we never compromise on cut quality.
Colour & Clarity
Diamond colour measures the absence of colour, while clarity refers to the tiny natural characteristics formed during a diamond's growth.
At Nyama, we typically work with:
Lab-Grown Diamonds
- EF Colour
- VVS–VS Clarity
Natural Diamonds
- HI Colour
- VS–SI Clarity
These specifications offer an excellent balance of beauty, brilliance, and value.
We also customise every piece to suit individual preferences and budgets, allowing you to choose the quality that's right for you.
Carat
Carat measures a diamond's weight—not its visible size.
Rather than focusing solely on carat weight, we believe in selecting diamonds with the best overall balance of brilliance, proportions, and visual appeal.

Every diamond shape has its own personality.

Our Diamond Standards
Every diamond selected for a Nyama piece is individually assessed to ensure it meets our standards for:
✓ Exceptional Brilliance
✓ Excellent Cut Quality
✓ Beautiful Colour
✓ Eye-Clean Clarity

Rather than selecting diamonds based solely on grading reports, we evaluate every stone for its overall beauty and performance.
Certification
All natural diamond solitaires are accompanied by an independent grading certificate from an internationally recognised gemological laboratory.
Lab-grown diamond solitaires weighing 0.99 carats and above also come with certification.
Diamonds below 0.99 carats are not routinely certified, but certification can be arranged upon request for an additional fee.
Depending on the diamond, certification may be provided by GIA or IGI.

Absolutely. We offer a range of colour and clarity combinations across both natural and lab-grown diamonds to suit individual preferences and budgets.
