Buyers' Guide

  • This first of its kind exercise maps each gemstone into 6 ‘similar’ Quality Buckets at ‘ideal weight ranges’ for comparing prices across product categories
  • The representative images used for each gem are for illustrating the quality range within the category; the actual shape, tone, clarity and origin may differ
  • While categories exists way above “Exotic” and also below “Classic” within each product, these would represent the affordable range for most people
  • We do not keep a running stock of gemstones in our inventory and each piece is individually selected by our astro-gemologists on exclusive request
  • Every gem is rigorously tested for authenticity at established laboratories such as GII, GTL, IGI-GTL, GTSC etc. with full disclosure of treatments (if any)
  • Apart from gemological parameters, each gem is also qualified to pass ‘Jyotish’ standards as outlined in sacred texts like ‘Garuda Purana’ and ‘Brihat Samhita’

East Africa / Some Heating / No Treatment / Purple Pink / Semi Translucent / Natural Fingerprints

Rs. 13,000 – Rs. 16,700 per ct.


Due to their exclusiveness, Ruby is the most exploited gem in the world. Not only Sapphires within the Corundum group, but also semi-precious gems like Almandine Garnet and Spinel are widely treated, recut and sold as “New Burma Mine” Rubies for less than Rs. 7,000 per carat. Please note, there is nothing called "New Burma Mine" in existence.


Since a flawless natural Ruby above a few carats is even rarer than diamonds, Ruby prices increases exponentially when moving from 3 to 4 carats. The legendary Burmese Pigeon Blood Ruby would cost above Rs, 225,000 per carat.


Over 85% of all Rubies mined are thermally treated at low temperatures to reduce mineral impurities and natural rutile inclusions. This is usually not considered as an enhancement. However, synthetic interventions like Cavity Filling by Glass, Flux Healing, Beryllium and Lead Diffusion is widely used that reduce the value of the gem by more than 95%.

RED CORAL | Planet: Mars | Species: Marine Polyp | 7.60 - 8.15 ct.


Japan / No Treatment / Ultra Rare Dark Ox Blood Red / Excellent Luster / No Spots / Natural Grains

Rs. 10,500 –Rs. 12,500 per ct.

Rs. 2,450 – Rs. 2,700 per ct.


Italy / No Treatment / Good Saturation and Tone / High Luster / Minor Natural Patterns

Rs. 1,850 – Rs. 2,100 per ct.


Mediterranean / No Treatment / Some Color Zoning / Medium Luster / Natural Grains

Rs. 1,300 – Rs. 1,550 per ct.

Color & Shape

Red Corals range from dark blood red to warm pink to orange-red. However, Mediterranean Ox Blood Red is the most desirable and is hence sold at a premium. Shape has no influence on the valuation of Red Corals, although triangular Red Corals are preferred for their astrological significance.

Origin Value

While Japanese Red Corals can command as much as 200% mark up over other varieties, in reality, ‘Japanese’ also include Red Corals from South Pacific Sea, while the ‘Italian’ variety also include those from the Atlantic region.


Of late, lacquer coated camel bones and multi-dyed wood (that resemble Red Coral texture) and even hard plastics are filling up the market. These are sold for less than Rs. 600 per carat and cannot be detected via Acetone or Hydrochloric Acid tests. The only way to identify Carotne, the popular coloring agent in Red Corals, is through Photoluminescence Spectroscopy.

EMERALD | Planet: Mercury | Species: Beryl | 4.80 - 5.45 ct.


Ethiopia / No Treatment / Insignificant Oiling / High Transparency / Eye Clean

Rs. 40,600 – Rs. 44,000 per ct.


Colombia / No Treatment / Minor Oiling / Good Clarity / Natural Feathers & Silk

Rs. 34,500 – Rs. 37,000 per ct.


Zambia / No Treatment / Minor Oiling / Very Good Clarity / Uniform Color & no Zoning

Rs. 25,000 – Rs. 27,600 per ct.


Columbia / No Treatment / Some Oiling / Semi Transparent / Some Silks & Needles

Rs. 18,500 – Rs. 21,000 per ct.


Brazil / No Treatment / Moderate Oiling / Translucent / Natural Inclusions

Rs. 12,800 – Rs. 14,500 per ct.


Zambia / No Treatment / Moderate Oiling / Some Color Zoning / Translucent

Rs. 8,500 – Rs. 10,200 per ct.

Origin Hype

Although Colombian Emeralds command a premium in the gemstone world, origin do not play a key role when it comes to astro-gemology. Almost every source country can produce gems of excellent color, luster and quality.

Inclusions & Oiling

Being a Type III gemstone, all natural Emeralds will always have inclusions (feathers, needles or silk) called Jardins that play a role in identifying natural Emeralds. Rare eye clean Emeralds can easily command beyond Rs. 85,000 per carat. Emeralds are also routinely oiled to moisturize their internal brittle structure. This is fully accepted and does not devalue the gemstone.

Artificial Treatments

Since Emeralds cannot be heated, Thailand has led the way in very innovative Beryl treatments to pass them as natural Emeralds. Undetectable even under a standard Chelsea Filter, these Polymer Raisins, Irradiation and Epoxy Fillings can only be identified by a Raman Spectrometer, which very few labs possess, and thus are able to declare.

YELLOW SAPPHIRE | Planet: Jupiter | Species: Corundum | 5.15 - 5.85 ct.


Sri Lanka / No Heating / No Treatment / Golden Lemon Yellow / Very Transparent

Rs. 42,500 – Rs. 45,000 per ct.


Burma / No Heating / No Treatment / Butter Yellow / Transparent / No Inclusions

Rs. 34,000 – Rs. 37,500 per ct.


Sri Lanka / No Heating / No Treatment / Excellent Color & Saturation / Transparent

Rs. 24,000 – Rs. 27,650 per ct.


Sri Lanka / No Heating / No Treatment / Medium Saturation & Clarity / Minor Visible Inclusions

Rs. 17,500 – Rs. 19,250 per ct.


Madagascar / No Heating / No Treatment / Semi Translucent / Some Color Zoning

Rs. 11,300 – Rs. 13,250 per ct.


East Africa / No Heating / No Treatment / Translucent / Medium Saturation

Rs. 7,300 – Rs. 9,600 per ct.

Color & Intensity

The most sought after colors for Yellow Sapphire, Golden Canary Yellow and Light Butter Yellow, are typically from Sri Lanka. Pure natural Yellow Sapphires are always low to medium in saturation. If the tonal intensity is very high, then a fully untreated, natural Yellow Sapphire will typically cost Rs. 65,000 per carat and above.

Clarity Enhancements

Over 90% of all Yellow Sapphires mined are always subject to very minor thermal heating to a) increase depth; and b) hide and/or dissolve minor rutile inclusions. While these are acceptable for jewelry, heating destroys the astrological properties of the gem making it unsuitable as a potent remedy.

Synthetic Treatments

Low grade sapphires are often subject to Beryllium Treatment, Glass Filling and Lattice Injection to increase their brilliance. These sophisticated can only be identified by an expert gemologist using various advanced instruments (not just a microscope). Any artificial treatment makes a gemstone redundant for gem-therapy in astrology.

WHITE SAPPHIRE | Planet: Venus | Species: Corundum | 5.20 - 5.75 ct.


Sri Lanka / No Heating / No Treatment / High Clarity / Excellent Luster / Loupe Clean

Rs. 47,500 – Rs. 50,000 per ct.


Sri Lanka / No Heating / No Treatment / Fully Transparent / No Zoning / Eye Clean

Rs. 37,000 – Rs. 41,500 per ct.


Burma / No Heating / No Treatment / Good Clarity & Luster / Some natural inclusions

Rs. 27,000 – Rs. 30,550 per ct.


Sri Lanka / No Heating / No Treatment / Translucent / No Tint / Lustrous

Rs. 19,500 – Rs. 22,000 per ct.


Sri Lanka / No Heating / No Treatment / Semi Translucent / Some Natural Inclusions

Rs. 13,500 – Rs. 16,550 per ct.


Sri Lanka / No Heating / No Treatment / Semi Translucent / No Tint or Zoning

Rs. 8,050 – Rs. 10,250 per ct.

Color & Tint

Totally colorless, without any secondary tint (orange, green or indigo) is the most desirable color of White Sapphire. These are the purest form of Sapphires because they lack any trace element that imparts color to Corundum; making them rare and precious.

Heat Treatments

Like the Yellow variant, White Sapphires are often heated to a) hide natural inclusions; and b) make them more appealing to look at. While acceptable as a jewellery, these are not suitable as an astro-remedy.

Market Dynamics

In a strange play of economics, higher demand for Yellow Sapphires has actually increased prices of untreated White Sapphires. Several manufacturers delve in the unscrupulous practice to artificially treat White Sapphires with heat, irradiation, dyes etc. to convert them into yellow variants. As a result, sourcing completely untreated, natural White Sapphires have become difficult, leading to higher prices.

BLUE SAPPHIRE | Planet: Saturn | Species: Corundum | 4.80 - 5.15 ct.


Sri Lanka / No Heating / No Treatment / Fully Transparent / Excellent Luster / Eye Clean

Rs. 47,200 – Rs. 49,000 per ct.


Sri Lanka / No Heating / No Treatment / Good Saturation / Some Natural Fingerprints

Rs. 40,500 – Rs. 42,250 per ct.


Sri Lanka / No Heating / No Treatment / Vivid Saturation / Visible Rutile Inclusions / Eye Clean

Rs. 30,200 – Rs. 32,650 per ct.


Burma / No Heating / No Treatment / Low Saturation / Minor Inclusions / Good Luster

Rs. 21,750 – Rs. 23,700 per ct.


Sri Lanka / No Heating / No Treatment / Low Saturation / Visible Inclusions / Low Luster

Rs. 15,500 – Rs. 17,250 per ct.


East Africa / No Heating / No Treatment / Low Clarity / Visible Natural Inclusions

Rs. 10,300 – Rs. 12,500 per ct.

Saturation & Clarity

Over 85% of all Blue Sapphires mined are always dull and unpleasant looking in raw form. Some heating below melting point is often done to make it acceptable and this is recognized by the trade. These heated gems are not ideal as astro-remedies.

If the saturation is too vivid along and it also has high transparency, such natural untreated Blue Sapphires will either cost beyond Rs. 65,000 per carat or will have undergone some enhancing artificial treatment.

Synthetic Treatments

Since flawless Blue Sapphires are rare, Titanium Treatment, Lattice Diffusion, Lead Flux Polymers, Chromophore Radiation, etc. have become the norm for their enhancement that few gem labs disclose.

Hue & Tone

The desired colors for Blue Sapphire are Royal Blue (Indraneelam), Cornflower Blue, Pastel Blue and Cobalt Violet Blue (most common). Most natural and untreated Blue Sapphires are lighter in tone and has medium hue.
