Understanding the Value of Your Diamond

Key Diamond Attributes
Selling Diamond Jewellery Across the UK
Selling diamond jewellery, such as rings, necklaces, or earrings, requires consideration of both the diamond and the setting. Factors that influence value include:
- Metal type: Gold, platinum, or silver affects resale value.
- Design quality: High-quality craftsmanship can add value.
- Condition of the piece: Wear or damage can reduce overall offers.
At Celsteel, we buy diamonds nationwide in any form loose stones or set in jewellery ensuring every seller gets a fair, transparent price. Learn more about our cash for diamonds service.

Lab-Grown vs Natural Diamonds: What Sellers Should Know
When selling diamonds, it’s important to know the difference between lab-grown and natural diamonds:
| Feature | Lab-Grown Diamonds | Natural Diamonds |
| Resale Value | NONE – usually not accepted for resale | Market-dependent; can retain value |
| Ethical Considerations | Often marketed as “ethical,” but energy use and rare earth extraction are significant | Can be sourced responsibly; emotional and cultural value retained |
| Emotional/Cultural Value | Limited; generally lower perceived significance | High; traditional and widely recognised |
| Cost | Lower initial purchase cost | Higher cost; potential resale recovers some value |
Important: Celsteel does not purchase lab-grown diamonds. We only offer cash for natural diamonds, whether loose or set in jewellery.
