If you have spent any time sourcing diamonds for a jewelry collection, you know that some stones carry a weight of rarity that goes beyond carat and clarity. Raw pink diamonds are in a category of their own. They are not simply a color variation of a white diamond. They are a geological event so unlikely, so specific in its requirements, that the world's entire annual supply of fine quality natural pink diamonds would fit inside a champagne glass.
That is not a marketing line. That was the documented reality of the Argyle mine at its peak. And Argyle is now closed.
At Gems Diamonds By Shikha (GDBS), we are one of the few wholesale suppliers in the USA market with a genuine, consistent collection of raw pink diamonds, rough pink diamonds, and loose natural pink diamonds, processed and cut at our own manufacturing unit in Surat. This guide tells you exactly what raw pink diamonds are, why they are so rare, where they come from in 2026, and how to evaluate and source them as a wholesale buyer.
What Are Raw Pink Diamonds?
Before understanding what makes raw pink diamonds so extraordinary, it helps to understand what separates them from other diamonds at the most fundamental level.
Natural loose pink diamonds are diamonds that occur in shades of pink, from delicate blush to vivid magenta, due to structural anomalies within the crystal lattice rather than chemical impurities. This last point is critical and is what makes pink diamonds scientifically unlike almost every other colored gemstone.
Most colored diamonds get their color from trace chemical elements. Blue diamonds contain boron. Yellow diamonds contain nitrogen. But pink diamonds contain no impurity that science has conclusively identified as the color cause. Instead, the leading theory is that structural distortion, known as plastic deformation, affects how light interacts with the stone, giving it a pink color. This extraordinary process also means that many do not survive formation, and those that do are often small or contain inclusions, making high-quality specimens exceedingly rare.
In practical terms for a wholesale buyer, this means:
Raw pink diamonds are pink diamonds in their completely unprocessed, natural crystal state, exactly as they emerge from the earth. Their rough surface, natural crystal geometry, and unaltered color make them deeply appealing for artisan jewelry, organic design aesthetics, and collectors who value provenance and naturalness.
Rough pink diamonds is a closely related term, often used interchangeably with raw. In trade contexts, rough typically refers to the uncut form before any faceting work. Both terms describe the same fundamental thing: a natural pink diamond that has not been faceted or polished into a standard gemstone shape.
Loose pink diamonds refers to any pink diamond, raw or polished, that is sold as an individual stone rather than as part of a finished setting.
At GDBS, we carry all three forms. Our pink diamond collection includes raw rough pink diamonds for artisan and organic designs, minimally processed raw stones for display and setting, rose cut loose pink diamonds, brilliant cut loose pink diamonds, and salt and pepper pink diamonds with unique inclusion patterns.
Why Are Raw Pink Diamonds So Rare? The Geology Explained
Pink diamond rarity is not a function of marketing. It is a function of geology, and the numbers are extraordinary.
Less than 0.15% of diamonds submitted to the Gemological Institute of America possess a predominantly pink color. Pink diamonds represent less than 0.1% of the world's total diamond production, making them one of the rarest gemstones on Earth.
To put that in context: of the hundreds of millions of carats of rough diamonds mined globally each year, the total annual production of natural pink diamonds of gem quality is measured in the low hundreds of carats. Everything. Worldwide. Per year.
The reason comes down to the formation process. Pink diamonds are typically found in smaller sizes because the same extreme geological forces that create their color also restrict their growth. Intense pressure deep within the Earth distorts the diamond's crystal lattice, known as plastic deformation, which alters how light moves through the stone and produces its pink hue.
In other words, the very process that creates the pink color also physically limits how large the stone can grow, and how many survive the journey from deep in the Earth's mantle to the surface intact.
Of all the diamonds found in a single year, only 1 in 100,000 could be graded as having a "fancy color," making natural fancy color diamonds one of the world's most extreme rarities. Out of all these colors, pink diamonds are considered the second rarest. Only red diamonds are scarcer.
Where Do Raw Pink Diamonds Come From in 2026?
This is the question every serious wholesale buyer in the USA needs to understand in 2026, because the supply landscape changed dramatically in 2020 and has not recovered.
The Argyle Mine: The Source That Changed Everything, Then Closed
It was not until the discovery of the Argyle Mine in Western Australia in the 1980s that a consistent, albeit limited, supply became available. Argyle quickly became synonymous with pink diamonds, producing an astonishing percentage of the world's supply and setting the standard for their vibrant colors. Its closure in 2020 marked a pivotal moment, further cementing the rarity and historical importance of these already scarce stones.
At its peak, the number of pink diamonds found at Argyle in one year could not fill a glass of champagne. And that was the world's primary source, accounting for 80 to 90% of global pink diamond production for decades.
Where Pink Diamonds Come From Now
Although the closure of the Argyle mine reshaped the global landscape for pink diamond supply, there have been discoveries in Russia, Africa, and Canada that help continue the legacy of these rare stones. Russian pink diamonds from the Siberian region yield small but notable numbers of pink diamonds. Russian stones are generally lighter in hue than Argyle gems. African mines in Tanzania and South Africa, although long known for white and yellow diamonds, sporadically yield vibrant pink diamond specimens. However, volumes remain extremely limited.
The pink diamond is one of the rarest colored diamonds that exist, rarer than every type of colored diamond apart from red diamonds. No new source has come close to replacing Argyle's volume or consistency. The supply contraction since 2020 is real, sustained, and directly driving price appreciation.
What This Means for Wholesale Buyers in the USA
Despite new sources, the global supply of pink diamonds in 2025 remains historically tight, and this extreme rarity underpins significant pink diamond price increases in the market. For wholesale buyers building collections, the implication is clear: pink diamonds sourced today at current wholesale prices are likely to be worth considerably more in three to five years. Designers who build pink diamond collections now are positioning ahead of an accelerating supply contraction.
How Pink Diamonds Are Graded: What Wholesale Buyers Must Know
Unlike white diamonds where color is measured on the D-to-Z scale (with D being colorless and most valuable), pink diamonds are graded on the GIA fancy color scale, where the presence and intensity of color is what determines value.
The GIA Pink Diamond Color Grades:
- Faint Pink
- Very Light Pink
- Light Pink
- Fancy Light Pink
- Fancy Pink
- Fancy Intense Pink
- Fancy Deep Pink
- Fancy Vivid Pink (highest value)
Only about 1 percent of pink diamonds qualify as Fancy Vivid, the top grade. For wholesale buyers, understanding where a stone sits on this scale is the single most important quality factor.
Secondary hues also matter. Pure pink stones are the most sought-after, but many also have secondary tones such as purple, orange, or brown. While purple-pink diamonds can be incredibly desirable, brownish-pink diamonds are generally less valuable.
For raw and rough pink diamonds specifically, color intensity can be harder to assess in the unpolished state because the surface texture scatters light differently than a polished face. This is where sourcing from a manufacturer with gemological expertise matters, because consistent color grading across a raw lot requires an experienced eye.
Carat weight in pink diamonds compounds value exponentially. Even stones under one carat can command premium prices. As the carat weight increases, so does the rarity, and value, of the diamond. A two-carat natural pink diamond of good color is not twice as rare as a one-carat stone. It is many times rarer, and priced accordingly.
Raw Pink Diamonds at Auction: Context for Wholesale Buyers
Understanding the auction market for pink diamonds gives wholesale buyers essential context for the value proposition they are offering retail clients.
The Pink Star Diamond, weighing 59.60 carats, is the largest Internally Flawless Fancy Vivid Pink diamond ever graded by the GIA. It fetched a staggering $71.2 million at auction in 2017.
Pink diamond price in 2025 typically exceeds $500,000 per carat for high quality stones, with Fancy Vivid pinks and stones exceeding 1 carat often selling above $2 million per carat at auction.
These are the benchmark prices for top-quality polished stones. Raw and rough pink diamonds at the wholesale level trade at dramatically lower price points, while carrying the same rarity narrative and origin story. For independent designers in the USA who want to offer a stone with genuine collector-level prestige at accessible price points, raw pink diamonds are one of the most compelling options in the current market.
Raw vs. Treated Pink Diamonds: The Critical Distinction
As pink diamond demand has surged and natural supply has contracted, the market for treated pink diamonds has grown substantially. Treated pink diamonds are natural white or light-colored diamonds that have undergone high-pressure high-temperature (HPHT) treatment or irradiation to artificially induce or intensify a pink color.
Today, the greatest risk is not selecting the wrong shade of pink, but purchasing a stone whose color is not natural, not permanent, or not properly documented. Pink diamonds should only be purchased from established, well-known suppliers with a long track record in the natural diamond industry.
For wholesale buyers, the implications are serious. Treated pink diamonds must be disclosed as treated. Undisclosed treated stones sold as natural is fraud. Color treatments can fade under heat exposure during jewelry making. And the value gap between a natural and treated pink diamond of similar appearance is enormous.
At GDBS, all pink diamonds are natural unless explicitly specified otherwise. For buyers who want lab grown pink diamonds as an ethical and affordable alternative, we carry those as a clearly identified separate category in our collection.

Frequently Asked Questions
Q: What is the difference between a raw pink diamond, a rough pink diamond, and a loose pink diamond?
A: Raw and rough pink diamonds both refer to uncut, unpolished pink diamonds in their natural crystal form, used directly in artisan jewelry or minimally processed for display. Loose pink diamond is a broader term covering any pink diamond, raw or polished, sold as an individual stone rather than in a setting. At GDBS, all three forms are available.
Q: Why are raw pink diamonds so rare?
A: Pink diamonds get their color from a rare structural distortion in the crystal lattice called plastic deformation, rather than from chemical impurities. This process is extraordinarily uncommon, limits how large the stones grow, and reduces how many survive formation intact. Less than 0.1% of all diamonds mined globally are pink, making them among the rarest gemstones on Earth.
Q: Where do raw pink diamonds come from now that the Argyle mine is closed?
A: The Argyle mine in Australia, historically responsible for 80 to 90% of global pink diamond supply, closed in 2020. Current sources include select mines in Russia (Siberia), Tanzania, South Africa, and Canada, though none match Argyle's volume or color intensity. Global supply remains historically tight and is driving sustained price appreciation.
Q: How do I tell a natural raw pink diamond from a treated one?
A: Visual inspection alone cannot reliably distinguish natural from treated pink color. For polished stones, GIA certification will state whether color is natural or treated. For raw and rough pink diamonds, sourcing from a reputable supplier with documented provenance is the most reliable protection. GDBS supplies only natural pink diamonds unless lab grown alternatives are explicitly specified.
Q: What color grades are available in GDBS raw pink diamonds?
A: GDBS raw pink diamonds range from light pink through fancy pink in body color. For specific color intensity requirements or GIA-graded parcel requests, contact Shikha directly through the wholesale enquiry page.
Q: Can I use raw pink diamonds directly in jewelry without cutting or polishing?
A: Yes, and this is one of the most distinctive uses in the current US artisan market. Raw pink diamonds set in bezels, wire-wrapped, or used as organic pendants create genuinely one-of-a-kind pieces with a rarity story that polished stones cannot replicate. GDBS supplies raw pink diamonds specifically suited to artisan and organic jewelry design.
Q: Are lab grown pink diamonds available at GDBS as well?
A: Yes. GDBS carries lab grown pink diamonds as a clearly identified alternative for buyers who want the pink diamond aesthetic at more accessible price points. These are fully disclosed as lab grown and priced accordingly, separate from the natural pink diamond collection.
