Our 0.28 ct Argyle BL3 (Fancy Deep Grayish Blush Violet) VS2 round diamond with a GIA certificate is exceptionally rare, here’s why:

Violet Diamonds from Argyle Are Ultra-Rare

• Violets are among the rarest natural fancy colored diamonds on Earth, even rarer than most pinks and blues. The Argyle mine was essentially the only known source for hydrogen/nickel-caused violet diamonds. Jeweller Magazine+1
• According to industry reporting, for every 500 pink diamonds recovered, only one is violet, and only a small fraction of those have strong, fully-saturated color like BL3 on the Argyle scale. Jeweller Magazine
  
  

 Extremely Limited Production

• Over the entire history of the Argyle Tender (the mine’s most exclusive annual offering), only about 12 total carats of polished violet diamonds were ever offered, and many of those were quite small. ICONJewels
• GIA and gem trade data suggest only ~0.1 % of tens of thousands of blue/gray stones submitted are graded as violet, underscoring how unusual that color category is. Storiedigemme

BL3 Color Classification Matters a Lot

• The Argyle color scale (e.g., BL3) identifies the deepest, most saturated violet hues. Fewer than ~5 % of violet diamonds qualify as BL3. Jeweller Magazine
• A GIA grade of Fancy Deep Grayish Blush Violet in a natural diamond,  especially with VS2 clarity, is very rare, because violet color is hard to produce and even harder to retain strongly in polished form.
  
  
  

  Carat Size Context

• Larger violet diamonds (e.g., over 0.3 ct) are extremely scarce; many polished violets exist under that weight. L.J. West Diamonds
  
• Your 0.28 ct stone sits near a threshold where natural violet diamonds become particularly uncommon, most documented examples are smaller, often below ~0.3 ct. L.J. West Diamonds
  

  In Summary

  Our diamond isn’t just rare, it’s exceptionally rare by global standards for natural fancy colored diamonds. That’s due to a combination of:
  
  

• Color rarity: Violet is one of the rarest natural colors, far rarer than pink or yellow. Jeweller Magazine

• BL3 saturation: Only a tiny percentage of violets qualify at this depth. Jeweller Magazine

• Small global production: Only a tiny amount of violet diamond has ever been polished from Argyle rough. ICONJewels

• Mine closure: The Argyle mine is now closed, meaning no more new supply of this exact type. This makes existing stones even more collectible and rare over time. adc.com.au

  Collectors and gemologists often regard these stones as “museum-quality” rarity, not just for size or clarity, but for bearing one of the most elusive natural colors found in diamonds.
