- Carat: Larger diamonds are rarer and more valuable.

- Colour: Diamonds closer to colourless (D–F grades) command higher value.
- Clarity: Fewer inclusions or blemishes mean higher resale potential.

2. Certification & Documentation
Diamonds graded by GIA, IGI, or HRD carry more credibility. Certified stones typically achieve higher resale prices. Bring your certificate when visiting our London store for a more accurate valuation.
3. Market Demand & Price Trends
Diamond prices fluctuate with market trends, consumer demand, and currency shifts. Selling when market demand is strong — such as during the wedding or festive seasons — can maximise your payout.
