Factors Affecting the Quality & Price of Chuni/Kempu Stone
Ruby stone (Manikya stone) is a rare and highly popular gemstone. The best quality ruby comes from a reputed origin and displays balance in colour saturation & consistency with minimal contamination. The international gemstone market uses globally accepted standards to assess the quality of rubies which can help customers understand how much are rubies worth.
Origin
- Last but not least, geographic origin is an important aspect that helps establish the value of a fine kempu. They are found in a variety of locations around the world, including Myanmar (formerly known as Burma), Sri Lanka, Thailand ruby, and Madagascar ruby.
- Original chuni stone price and quality of rubies can vary greatly depending on their origin and other factors such as size, clarity, and cut. Burmese kempu is the most expensive ruby origin because of its exceptional colour quality. However, African chunni stones command a high ruby rate in the market nowadays.
- On a per carat basis, Old Burma chuni stone price ranges between INR 90,000 to 1,20,000, and Mozambique original kempu stone price can draw up to INR 90, 000. While Thailand ruby is economical, costing up to just INR 5,000, Indian chuni stone is even cheaper.
Colour
Kempu stone (in English called rubies) belongs to the dichroic mineral family which means that the gem reflects different light depending on different directions the light travels from. Generally, the colour can single-handedly influence the kempu stone price per ratti.
According to GIA, the finest kempu stone has a pure, vibrant red to slightly purplish red colour. In most markets, pure red colours command the highest prices, and chunni with overtones of orange and purple are less valued.
Clarity
Clarity is widely judged based on the number of inclusions found in the kempu or chuni gemstone. A real kempu stone without internal flaws is pretty much impossible to find. Kempu with inclusions not visible to the naked eye are extremely rare. Thus, chuni pathor price will be significantly high for such a natural, inclusion-free ruby.
Carat Weight
A flawless, natural ruby gemstone above a few carats, is rare to find, even rarer than diamonds. Therefore, the ruby stone/Chuni stone price per carat increases exponentially when moving from one-carat ruby to three or four-carat ruby.
Cut
The way a ruby is cut can contribute around 10-20% to the cost of Ruby. Faceted cut ruby is brilliantly enhanced but incurs significant stone wastage as well. For the same quality, a faceted ruby costs more than a ruby cabochon.

Chuni Stone Cleaning & Care Guidelines
Taking proper care methods protects the brilliance while preserving the durability of your Chuni (Ruby) stone. When you practice easy cleaning practices along with proper storage solutions and scheduled inspections your gemstone maintains its brilliance throughout many years.
Avoid Exposure
Your stone needs protection from both sunlight exposure and corrosive chemicals because both conditions can cause its beautiful red colour to gradually fade away. High heat levels combined with strong detergents and fragrances can reduce the structural integrity of your stone over time so practice gentle handling.
Clean Gently
For optimal appearance, maintain the Chuni panna stone by rubbing it gently with soapy water using soft fabric. Apply soft cloths and neutral soapy water when cleaning because aggressive materials cause stone surface deterioration that ultimately erodes natural shine.
Store Safely
Arrange your Chuni stone jewellery inside fabric pouches or soft-lined containers because they stop scratches from developing. Ruby necklace should be isolated alone to stay scratch-free because diamonds possess higher hardness levels that can mar its elegant surface.
Regular Inspections
Regularly inspect your gemstone jewellery to ensure all settings stay in place and to detect any signs of wear. When you have your gemstone examined by a professional on a regular basis your stone will maintain stability while maintaining its brilliant appearance during extended periods.
Original Kempu Stone Buyer Beware Guidelines
When choosing a Kempu Stone which is also called Chuni or Ruby, buyers need to consider not only colour and carat weight. Authenticity, treatment status, origin claims, certification, clarity, cut, price, and seller’s honesty have a significant impact on both the value of a gemstone and its applicability in the future.
- Verify Natural vs Lab-Grown: Ruby may be either natural or lab-grown and sometimes visual examination is not sufficient to differentiate these two types. In case of expensive Kempu Stones, it is essential to have an independent gemological report which clearly states whether the stone is natural or lab-grown.
- Consider The Colour Cautiously: Fine Kempu Stones normally have a rich red to purplish-red colour. Stones that appear too dark, too pale, too orange, or too purplish could be considered less attractive; thus, colour evaluation through a comparison of the stone’s colour against edited photos of the same product is not advisable.
- Examine the Certificate Properly: A certified laboratory certificate may be able to indicate whether the Ruby is natural or lab-created, detect any treatment, note dimensions and color, and even give its opinion on provenance in some cases. The GIA certifies Ruby, though not with a specific quality rating.
- Compare Price to Quality: Beware the low-priced, very colorful and seemingly perfect Ruby. Price must be balanced in comparison with color, clarity, weight, cut, treatment, certification, and provenance of the stone, rather than just with its size.
- Make a Purchase from a Reputable Vendor: It is better to buy Kempu Stones from those jewelers or sellers who are transparent about carat weight, dimensions, treatment details, certificates, photos or videos, price, returns policy and invoices of their products.
