Understanding Diamond Rates in India
Buying diamonds in India is both an emotional and financial investment. Unlike gold, which has a standard rate per gram published daily, diamond rates are more complex and depend on specific attributes known as the 4Cs: Cut, Color, Clarity, and Carat Weight. This Diamond Rate Calculator India helps you estimate the final cost of a loose diamond or diamond jewelry piece by factoring in the carat rate, making charges, and the applicable GST.
How Diamond Prices are Calculated
The price of a diamond is primarily determined by the "Rate per Carat." However, this rate is not linear. A 2-carat diamond is not simply twice the price of a 1-carat diamond; it is often much more expensive per carat due to the rarity of larger stones. The calculation logic used above follows this formula:
- Base Cost: Carat Weight × Rate Per Carat.
- Subtotal: Base Cost + Making Charges (Labor/Setting costs).
- Final Price: Subtotal + GST (Goods and Services Tax).
The 4Cs and Their Impact on Rate per Carat
When entering the "Rate Per Carat" in the calculator above, it is crucial to understand what drives this number:
- Carat: The weight of the diamond. 1 Carat = 0.2 grams = 100 cents.
- Cut: This refers to the symmetry, proportion, and polish. An 'Excellent' cut reflects light best and commands a higher premium than a 'Good' or 'Fair' cut.
- Color: Graded from D (Colorless, most expensive) to Z (Light Yellow). In India, ranges from D-F are considered premium, while G-J are popular value choices.
- Clarity: Measures internal inclusions. FL (Flawless) is the most expensive. Common commercial grades in India include VVS (Very Very Slightly Included), VS, and SI (Slightly Included).
Pro Tip: In India, the standard GST rate for diamond and gold jewelry is currently 3%. Always ensure you receive a tax invoice and a certification card (like GIA, IGI, or HRD) to verify the authenticity and grade of your purchase.
