Citrine (Sunela) Buying Guide: Price per Carat, Heated vs Natural, and the Pukhraj Upratna

Citrine, known in India as Sunela, is the yellow to golden-orange variety of quartz. Sometimes called "the merchant's stone", it is linked in tradition with prosperity, and in Vedic tradition it is the best-known substitute (upratna) for Yellow Sapphire (Pukhraj). This guide explains how natural citrine differs from heated amethyst, how a laboratory tells them apart, how to judge colour, clarity and cut, what Sunela costs, and how to look after it.

Sunela in Vedic Tradition

In Vedic tradition, Citrine (Sunela) is a well-known upratna for Jupiter (Guru), the planet of Yellow Sapphire (Pukhraj). It is traditionally associated with wisdom, learning and business. The customs below are the ones most often followed; whether a stone suits you, and at what weight, is for your own astrologer or Pandit ji to advise.

Choosing a size: a common Indian custom links stone size to body weight: about 1 Ratti for every 10 kg, so 7 Ratti for someone who weighs 70 kg. One Ratti (the pakki ratti used on our listings) is 0.91 carat, so 1 carat is about 1.1 Ratti. Every Ratna Gems listing gives the weight in both carats and ratti.

Heated Amethyst or Natural Citrine: What Actually Differs

Natural citrine is rare. Most citrine on the world market began as amethyst — occasionally smoky quartz — that was heated in a kiln to several hundred degrees Celsius until it turned yellow or orange. This is worth understanding properly, because it is the most misrepresented fact about the stone in both directions: some sellers hide it, and others use it to frighten buyers.

• Same mineral, different history. Natural and heated citrine are both quartz, with the same hardness of 7, the same specific gravity of 2.65 and the same chemistry. In heated amethyst the yellow comes from iron impurities changed by the kiln's heat; the cause of colour in natural citrine is still debated by gemmologists, with aluminium-related colour centres and iron both proposed. Heating adds nothing to the stone.
• What tradition holds. Citrine is the most widely used upratna for Pukhraj in India, and much of the Sunela worn for Jupiter has been heated; many astrologers accept it. Some traditions prefer unheated stone where it can be found, just as unheated sapphire is preferred over heated. Either way, tradition asks for genuine quartz of the right Ratti weight, and your own astrologer or Pandit ji is the person to ask.
• What is worth refusing. Not heat, but silence. A seller who states plainly that a stone is heat-treated is following standard trade practice. A seller who charges unheated prices while only implying a stone is unheated is not. Every Ratna Gems citrine listing states its treatment, and our current Brazilian Sunela is listed as unheated and untreated.

How to Buy an Original Citrine Stone: A Step-by-Step Guide

Step 1: Understand Natural vs. Heat-Treated Citrine

Start with the honest position: telling natural citrine from heated amethyst takes a gemmologist's instruments, and no home test settles it. These are the clues worth knowing, and what each one can and cannot tell you:

• Dichroism is the laboratory clue. Seen through a dichroscope, natural citrine usually shows two slightly different shades of yellow (weak dichroism), while amethyst heated to a citrine colour usually shows none. The effect is faint, needs the instrument and practice, and heated smoky quartz can keep its dichroism, so a gemmologist treats it as one clue among several rather than a verdict on its own.
• The white geode base applies to clusters, not cut stones. On heated amethyst geodes you often see a chalky white or grey base under a deep orange tip, and that is a genuine indicator — on a rough cluster. Once a stone is faceted the base is cut away, so the test has nothing to read. It tells you nothing about a polished Sunela.
• Colour is a guide to the market, not to the mine. Pale lemon and honey tones are more often natural; a deep reddish-orange, sold under the trade name "Madeira", is usually heated. Treat this as a probability rather than proof, and rely on the laboratory report and the seller's written statement for the actual answer.

Step 2: Understand Citrine Origins

Most citrine, both natural and heated, comes from Brazil, but natural citrine is also found elsewhere:

• Brazil: the main source of citrine of both kinds, and of the amethyst that is heated to make citrine. Our Sunela is Brazilian.
• Bolivia: Famous for the Anahi mine, which produces a unique bicolor stone called "ametrine" that is part amethyst and part natural citrine.
• Madagascar & Russia: also known sources of natural citrine.

Step 3: Evaluate the Color

Whether natural or heated, colour is the main value factor. The finest citrine is a saturated yellow to reddish orange without brownish or smoky tints; very pale stones, and stones with a brownish cast, are worth less.

Step 4: Assess the Clarity

High-quality Citrine, both natural and treated, is typically "eye-clean," meaning it has no inclusions visible to the naked eye. As a type of quartz, clean material is abundant, so there is little reason to buy a stone with visible flaws unless the price reflects them.

Step 5: Examine the Cut and Shape

A well-executed cut is essential to maximize the brilliance and sparkle of a Citrine. A good cut will ensure the stone reflects light evenly and shows off its beautiful color. Look for even colour across the face of the stone, without a washed-out window in the centre. Citrine is cut in almost every shape; our current stones are oval, pearl-drop and octagon step cuts.

Step 6: Verify Authenticity

The main challenge is not telling citrine from glass — that is straightforward for a laboratory — but knowing whether a stone is natural or heat-treated. A laboratory confirms the material as natural quartz and examines it for treatment with a dichroscope and other instruments. Ask for a report, and a listing, that both state the treatment in writing. Every Ratna Gems stone ships with a free report from an independent, ISO-certified laboratory, and on the product page you can add a GII, IIGJ or IGI report, priced by carat weight. Our guide to buying gemstones online safely explains how to verify a report yourself.

Step 7: Purchase from a Reputable Seller

Buy from a seller who states the species, weight and treatment of each stone in writing and offers a clear return policy. A reputable seller discloses heat treatment as a matter of course, and the price should match what is disclosed: unheated stones are not sold at heated prices, and heated stones should not be priced as unheated. Our gemstone buying guide covers the checks that apply to every stone.

Citrine (Sunela) Price in India (2026)

Citrine puts a Jupiter stone of the traditional Ratti weight within almost anyone's reach, which is why it is the most widely used upratna for Pukhraj. Price rises with weight, depth of colour and clarity, and fine, large stones cost more per carat. At Ratna Gems, natural Brazilian Sunela — listed as unheated and untreated, with an independent laboratory report — is priced at a single rate of ₹150 per carat. These are stones in stock in October 2026:

Care and Maintenance: Color Fading Warnings

Citrine is durable, with a Mohs hardness of 7 and no cleavage, but a few simple habits keep its colour and polish at their best:

• Keep it out of strong sun and heat: some citrine can pale after long exposure to strong sunlight or heat, so store the piece away from a sunny windowsill when you are not wearing it, and keep it away from steam cleaners and high heat. Normal wear is not a problem.
• Chemical Exposure: Avoid exposure to harsh detergents, hair sprays, and household chemicals. Clean using warm soapy water and a soft-bristled brush.
