Citrine Cut Gemstones

Custom cut citrine in heart, oval and trillion outlines, running from 27 to over 40 carats and measured in millimetres.

Buy Loose Citrine Cut Gemstones by Carat Weight, Colour Grade and Cut

Citrine is the yellow to reddish brown variety of quartz, coloured by traces of iron in the silicon dioxide lattice, and it sits at Mohs 7 with a specific gravity of 2.65 and a refractive index between 1.544 and 1.553. Astro Gallery of Gems buys citrine rough at the shows, commissions the faceting as heart, oval and trillion outlines rather than ordering calibrated parcels, then weighs each finished stone in carats and measures all three dimensions in millimetres. Every one of the 5 loose stones on this page is sold singly and priced on its own weight, colour and cut.

Compare Carat Weight Against Price on Every Stone in Stock

Price per carat climbs steeply once a citrine passes 25 carats, because rough that yields a clean stone of that size is uncommon. Astro Gallery of Gems prices each gem against its own weight, saturation and cut quality. A stone that sells drops out of the table below rather than staying on as a dead link.

Read the Colour Grade Before You Read the Carat Weight

Colour decides a citrine price more sharply than weight does, and the trade names its bands rather than numbering them. The stones cut for this page run reddish brown to orange brown, which places them at the deeper end. Astro Gallery of Gems photographs each gem face up under neutral light so the tone you judge on screen matches the tone in the hand.

Colour bandHow it reads and what it suits
MadeiraDeep reddish brown with an orange core, named after the fortified wine, which holds its saturation in a large stone and commands the strongest prices in this range.
PalmeiraWarm orange brown a shade lighter than Madeira, the band most of the gems cut here occupy, and the easiest colour to match across a pair of earrings.
Deep goldenClear saturated yellow with no brown cast, favoured for pendants because it carries colour under artificial light where paler material washes out.
Lemon and pale yellowLight greenish to straw yellow, sold across the trade as lemon quartz, which needs weight above 20 carats to show any real depth of colour.
Smoky bordered and ametrineMaterial where the citrine zone meets grey smoky quartz or purple amethyst in the same crystal, cut deliberately to keep the boundary visible in the finished gem.

Ask Where the Quartz Grew and Whether Heat Was Used

Most citrine in world trade began as amethyst and turned yellow in a furnace between roughly 470 and 560 degrees Celsius. That is a permanent, stable change accepted throughout the gem trade, and it is not a fault. Astro Gallery of Gems will confirm the treatment status of any individual gem before you buy, because the answer moves the price.

Rio Grande do Sul, BrazilThe basalt hosted amethyst geodes of southern Brazil supply the majority of the world's heated citrine. Kilns there convert pale amethyst into the golden and Madeira bands, and the volume from this one state is what keeps large citrine affordable at all.
Minas Gerais, BrazilPegmatite and vein quartz from Minas Gerais yields the cleanest large rough, which is why custom cut stones above 30 carats trace back here. Astro Gallery of Gems buys from this material when a heart or trillion outline needs an inclusion free block.
The Anahi mine, BoliviaAnahi in the Santa Cruz department produces citrine that formed yellow underground, along with ametrine showing purple and gold in one crystal. Unheated Bolivian material carries a premium, and gemmologists separate it partly by its distinctive colour zoning.
The iron colour centreCitrine owes its yellow to ferric iron substituting into the silicon dioxide framework and to colour centres activated by natural radiation or by heat. That chemistry explains why the same crystal can be amethyst at one end and citrine at the other.

Inspect the Cut for Window, Extinction and Symmetry

A citrine loses more value to poor faceting than to a small inclusion, since quartz is priced on colour and light return rather than on clarity alone. Four faults account for most of it, and each is visible in a face up photograph.

Window through the pavilionTilt the gem face up over printed text. If the letters read through the middle, the pavilion is too shallow and light is escaping through the back instead of returning to your eye. A window drains colour from even a well saturated Madeira stone.
Extinction across the tableDark unlit patches under the table mean facets are meeting at angles that leak light. Quartz has a narrow tolerance here, so a precision cut 36 carat oval will out perform a heavier native cut stone of the same colour band.
Symmetry of outline and girdleLay a straight edge across a photograph of a trillion and check that the three sides and corners match. An uneven girdle thickness forces a jeweller to compensate with the setting, which adds bench time and can weaken a prong.
Polish and colour zoningLook for wheel marks or a slightly cloudy facet under raking light, then check whether colour concentrates in one corner rather than spreading. Astro Gallery of Gems states any visible zoning in the description rather than shooting around it.

Choose Calibrated Millimetres or a Freeform Custom Cut

Calibrated stonesCalibrated citrine is cut to standard millimetre sizes so it drops into a commercial mounting without alteration. Designers ordering multiples for a production run need this, and it trades close to a per carat market rate because any stone of the same grade substitutes for any other.
Custom and freeform cutsThe gems here are custom cut to weights such as 27, 30, 36.5 and 40.5 carats, with outlines following the rough rather than a template. A jeweller builds the mounting around the stone instead of the reverse, which suits a single commissioned ring, pendant or brooch.

Decode Table, Girdle and Extinction on a Gemstone Listing

TableThe large flat facet on top of a faceted gem, whose width relative to the outline governs how much brilliance the stone returns.
PavilionThe cone shaped lower half beneath the girdle, where the facet angles decide whether light reflects back to the eye or leaks away.
GirdleThe narrow band around the widest point of a gem, gripped by prongs or a bezel, measured in millimetres on every listing here.
TrillionA triangular brilliant outline with curved or straight sides, which shows more spread per carat than an oval of equal weight.
Native cutA stone faceted near the mine to save weight rather than to optimise light return, leaving it heavier and deeper than a precision cut equivalent.
AmetrineBicoloured quartz combining amethyst purple and citrine gold in one crystal, cut so the boundary sits square across the finished gem.

Set It, Wear It or Keep It Loose in the Parcel

A 30 carat citrine measuring 26 by 19 millimetres is a centre stone, not an accent. Jewellers mount gems of this scale as cocktail rings, pendants and brooches, and a four prong basket or a rub over bezel both work at Mohs 7. Citrine is the recognised birthstone for November and a traditional thirteenth anniversary gift, which drives much of the gifting demand here. Crystal buyers know the same material as the merchant stone and associate it with the solar plexus chakra and with abundance. Astro Gallery of Gems documents weight, dimensions, colour band and treatment, and states no health or spiritual effect for any gem listed.

Clean a Faceted Citrine Without Dulling the Polish

Quartz at Mohs 7 resists scratching from dust and most household contact, so a loose citrine survives ordinary handling well. Wash it in warm water with a drop of detergent, brush the pavilion facets with a soft toothbrush, then rinse and dry on a lint free cloth. Keep the gem away from steam cleaners and from sudden temperature change, because heat treated material can fracture along an existing feather. Prolonged strong sunlight fades some citrine over years, so store loose stones in a paper parcel or a padded box rather than on a bright windowsill.

Settle Payment and Insure the Gem in Transit

The figure beside a gem is the figure charged. Move the stone into your cart, and Shop Pay, PayPal, Apple Pay, Google Pay, Visa and Mastercard all clear through a secure checkout. Astro Gallery of Gems then sends an itemised invoice recording the carat weight, the millimetre dimensions, the cut and the colour band. Your jeweller will want that document before quoting on a mounting. Ask the team beforehand for the gem shot against a white card, a measurement across the girdle, or a note on treatment, and those details come back by email.

Astro Gallery of Gems has traded loose gemstones out of New York since 1961, and a small parcel gets more attention than its weight suggests. Each stone leaves in a folded gem paper inside a lidded box, cushioned within an outer carton so the girdle never contacts another gem. The gallery ships gems tracked and fully insured to every country it serves, files the customs paperwork ahead of collection, and declares the value shown on your invoice. Astro Gallery of Gems backs each sale with the returns policy and the guarantee recorded on about us.

Resolve the Eight Questions Citrine Buyers Send Most

How much does a loose citrine gemstone cost?
Price follows carat weight, colour band and cut quality together, and the custom cut stones here run from the high twenties of carats upward. Live figures for every gem currently held sit in the table above, and none of them derives from a per carat average.
Is this citrine natural or heat treated amethyst?
Most citrine in the world trade is amethyst heated to between roughly 470 and 560 degrees Celsius, which is a permanent and accepted change. Unheated material from the Anahi mine in Bolivia carries a premium. Ask the gallery about a specific stone and the treatment status will be confirmed before you pay.
What is Madeira citrine?
Madeira is the trade name for the deepest reddish brown to orange brown grade of citrine, taken from the colour of the fortified wine. Palmeira sits a shade lighter, and golden and lemon grades sit lighter again. Colour band influences price more strongly than carat weight alone.
What size is a 30 carat citrine in millimetres?
The 30 carat heart cut here measures 26 by 19 by 17 millimetres, and the 40.5 carat oval measures 27 by 19 by 14 millimetres. Every listing states all three dimensions, because millimetre size rather than carat weight determines whether a stone fits a mounting.
Are these stones calibrated for standard settings?
No. Each gem is custom cut to follow its own rough, so weights and outlines fall outside standard calibrated millimetre sizes. A jeweller builds or adapts the mounting around the stone, which is the normal approach for a single centre gem of this scale.
Is citrine hard enough for a ring?
Yes. Citrine is quartz at Mohs 7, which handles daily wear in a ring provided the setting protects the girdle. A rub over bezel or a well seated four prong basket both work, and avoiding knocks against stone and metal surfaces preserves the polish.
How should a loose citrine be cleaned?
Wash it in warm water with a little detergent, brush the pavilion with a soft toothbrush, then rinse and dry on a lint free cloth. Keep the gem out of steam cleaners and away from abrupt temperature changes, since heat treated quartz can part along an existing feather.
Will you ship a loose gemstone overseas and can I return it?
Yes to both. A gem travels in folded gem paper inside a cushioned box, under full insurance and tracking, and the gallery files the export and customs documents ahead of collection. The returns page sets the conditions for sending a gem back, and additional photographs requested beforehand settle most questions.

Follow Citrine Into Quartz, Settings and Gifts

Citrine sits inside the quartz family and inside the loose gem trade at the same time, so buyers move outward in two directions. Collectors of the species follow amethyst and ametrine, while buyers shopping for a centre stone compare other cut material by carat and millimetre.
