Understanding United States Customer Preferences

The fine jewellery landscape in United States is experiencing sustained growth. Here is what American consumers and bridal shoppers are actively seeking — and how jewellers can maximize profitability.

Preference #1

High Demand for 2.00ct to 5.00ct+ Solitaires

Over 70% of modern American bridal couples choose lab-grown diamonds to achieve show-stopping 2.5ct, 3ct, and 4ct+ engagement centerpieces within accessible $2,500 to $6,000 retail budgets.

Preference #2

Strict D–F Colourless & Eye-Clean Clarity

US clients demand immaculate visual purity. Our Type IIa CVD diamonds are cultivated with zero trace nitrogen, ensuring icy D, E, and F color grades with VVS1 to VS2 clarity.

Preference #3

Oval, Radiant & Elongated Fancy Cuts

American brides favor finger-flattering elongated cuts. Oval is the #1 requested shape across the US, followed by Radiant, Elongated Cushion, and Emerald step cuts.

Preference #4

Traceable, Conflict-Free Sustainability

Millennial and Gen-Z consumers prioritize verified ethical provenance, zero mining impact, and clean laboratory origins backed by strict ESG standards.

Preference #5

IGI & GIA Laser Inscription Verification

American buyers expect independent certification. Every solitaire includes an authentic IGI or GIA grading report and matching microscopic laser inscription.

Preference #6

50%–70% Sourcing Cost Reduction
