Scientific Assaying Standards

Certified gemstone testing requires advanced molecular scans. We check for thermal diffusion, lead glass fills, organic dyes, and composite overlays at our Rohini laboratory.

Raman Spectroscopy

Exposing samples to high-intensity laser beams provides a chemical footprint, immediately identifying natural versus synthetic corundum or crystal fillers.

Laser Wavelength: 532nm

Refractive Index (RI)

Measuring the speed of light refraction within the stone allows us to define doublets, triplets, or synthetic glass mockups with total precision.

Treatment Detection

Thermal treatment, fracture filling with lead glass, diffusion of beryllium, and oil filling in emeralds are cataloged to evaluate true valuation.

Vedic Gemology Integration

In Vedic astrology, natural, untreated gemstones function as cosmic transmitters, focusing planetary radiation into the wearer's field. If a gemstone is treated with high heat, chemicals, or lead glass-fillers, its crystal lattice is fractured, making it astrologically ineffective.

Delhi Gold Testing (AGL) provides dedicated Vedic Suitability Assays, certifying that the gemstone is completely untreated, natural, and possesses the correct clarity to transmit planetary frequencies.

Frequently Asked Questions

Find answers to the most common queries regarding gemstone certification in Delhi, treatment scans, and Vedic planetary wear suitability.

What is an astrological gemstone and why must it be untreated?

keyboard_arrow_down
In Vedic Jyotish, a gemstone acts as a physical conduit that captures and transmits specific planetary rays into the body's subtle energy channels. Heating, beryllium diffusion, or glass-filling permanently alters the stone's crystalline structure and chemical composition, disrupting its natural refractive properties. Consequently, treated stones are rendered astrologically inert and fail to provide the desired remedial benefits.

How does Delhi Gold Testing gemstone testing laboratory in Delhi identify treatments?

keyboard_arrow_down
At our Rohini testing laboratory, we utilize high-precision instruments including laser Raman Spectroscopy (532nm) to analyze internal mineral structures, gemstone refractometers to check refractive indices down to 0.001 RI, and high-power gemological microscopes to locate signature gas bubbles, flux residues, and thermal stress cracks indicative of artificial heating or glass-filling.

What gemstones are tested for Vedic astrology suitability at your Rohini lab?

keyboard_arrow_down
We perform comprehensive tests on the Navaratna (nine primary astrological gemstones), including Blue Sapphire (Neelam), Yellow Sapphire (Pukhraj), Ruby (Manik), Emerald (Panna), Red Coral (Moonga), Pearl (Moti), Hessonite (Gomed), Cat's Eye (Lehsuniya), and Diamond (Heera). We check each specimen for organic chemical structure and geological origin.

What information does an AGL Gemstone Purity Certificate contain?

keyboard_arrow_down
An AGL Gemstone Certificate contains the exact weight (in carats and ratti), shape/cut style, dimensions, color, species and mineral family, refractive index, and specific gravity. Crucially, it lists diagnostic findings on treatment status (e.g., No Indication of Heating) and origin, accompanied by a secure online report lookup QR code.
