Why Carat Drop
Built On Verification, Not Persuasion
IGI Certified
Every listed certified diamond includes independent grading documentation.
Direct Pricing
Our sourcing model allows us to offer exceptional diamonds without traditional retail markups.
Hand Selected
We prioritize visual appearance, proportions and overall beauty — not simply the grading report.
Insured Delivery
Diamonds are securely packaged and shipped using insured delivery.
Certification
Every Diamond Independently Certified
Carat Drop diamonds are independently graded by the International Gemological Institute. Each stone is accompanied by a grading report documenting its measurements, carat weight, colour, clarity, finish and — explicitly — its identity as a laboratory-grown diamond.
Most certified stones carry a microscopic laser inscription on the girdle repeating the report number, so you can match the physical diamond to its paperwork and verify the report directly with the issuing laboratory.
Carat Drop is an independent retailer. We are not affiliated with, or endorsed by, IGI.
