Frequently Asked Questions โ Diamond Price in Japan How is diamond price calculated per carat? + Unlike gold, diamonds have no single spot price โ each stone is unique. Diamond prices are determined by the 4Cs: Cut (quality of craftsmanship), Color (D to Z scale, D being colorless), Clarity (FL to I3, measuring inclusions), and Carat weight. The Rapaport Price List is the industry benchmark used by diamond traders globally. Retail prices are typically 20-40% above the Rapaport list. Our prices are average retail reference prices per carat for each grade combination.
Which diamond grade is best value to buy? + For the best visual quality at the lowest cost, experts recommend: Color G-H (near colorless โ difference from D is invisible to naked eye), Clarity SI1-SI2 (inclusions not visible without magnification), Cut Excellent or Very Good. A G-SI1 one-carat diamond looks nearly identical to a D-IF to the naked eye at 40-60% lower cost. Always buy GIA, IGI or AGS certified diamonds. Lab-grown diamonds offer 60-80% lower prices than natural diamonds with identical chemical properties.
What is the diamond price in India per carat? + Diamond prices in India are quoted per carat (0.2 grams). A 1 carat natural diamond ranges from โน2,50,000 (I-SI2 grade) to โน15,00,000+ (D-IF grade) depending on the 4Cs. Lab-grown diamonds are 60-80% cheaper. India is the world's largest diamond cutting and polishing centre โ Surat processes ~90% of the world's rough diamonds. Import duty on rough diamonds is nil, while polished diamonds attract 5% duty.
