Which HS code applies to lab-grown diamonds from India?
Usually HS 710491. United Kingdom applies its own national tariff extension to the 6-digit code; confirm the full line with your broker.
Are lab-grown diamonds real diamonds?
Yes. They have the same chemical and physical properties as mined diamonds, but must be sold and described as laboratory-grown.
CVD or HPHT?
Both make true diamond. CVD dominates larger Indian production; HPHT is common for melee and some colours. Grading reports state the method.
Do the stones come with certificates?
Larger stones come with IGI, GIA or similar reports and a laser inscription. Melee is sold in graded parcels.
