Natural Diamond Rings vs Lab Grown Diamond Rings

Eternz carries both natural and lab grown diamond rings, giving you a choice based on your preference, values, and budget.

Natural Diamond Rings: Mined from the earth and certified by IGI, GIA, or SGL. Each natural diamond is graded on the 4Cs: Cut, Colour, Clarity, and Carat. Natural diamonds carry traditional value and are the standard choice for engagement rings, wedding bands, and heirloom pieces.
Lab Grown Diamond Rings: Lab grown diamonds are chemically, physically, and optically identical to natural diamonds. They are grown in controlled laboratory environments using HPHT or CVD technology and carry the same IGI or SGL certification as mined stones. Lab grown options typically cost 30 to 50 percent less than natural diamonds of the same grade, making them an increasingly popular choice in India for engagements, anniversaries, and daily wear.

Understanding Diamond Quality: The 4Cs

Every certified diamond on Eternz is graded by an independent laboratory on four internationally recognised criteria:

Cut: Determines how well the diamond reflects light. Excellent and Very Good cuts produce the most brilliance. Cut has the greatest impact on a diamond's visual sparkle.
Colour: Graded on a D to Z scale. D to F is colourless (most valuable), G to J is near-colourless (most popular for everyday and engagement rings), and K onwards shows a faint yellow tint.
Clarity: Measures internal inclusions and surface blemishes. FL (Flawless) to VS2 (Very Slightly Included) are the most popular grades for engagement rings. SI1 and SI2 offer strong value with inclusions invisible to the naked eye.
Carat: The weight of the diamond. For Indian buyers, 0.30 to 0.50 carat is the most popular range for daily wear, while 0.50 to 1.0 carat is standard for engagement rings.

Certification and Authenticity

Every diamond ring listed on Eternz carries independent third-party certification. Depending on the brand, this includes:

IGI (International Gemological Institute): The most widely used certification body for both lab grown and natural diamond jewellery in India.
GIA (Gemological Institute of America): The most internationally recognised diamond certification. Present in select premium brands on Eternz.
SGL (Solitaire Gemological Laboratories): An India-based lab widely accepted across the Indian diamond jewellery industry.
BIS Hallmarking: All gold settings on Eternz are BIS hallmarked for gold purity under the Bureau of Indian Standards.
