Compare Blue Monday Specimen 4 and Specimen 6 one-off iridescent pendants. See price, rarity, and style trade-offs to pick your fit.
Quick answer
Both Blue Monday Specimen 4 and Specimen 6 are one-off iridescent pendants from the same limited Blue Monday drop, so the real difference comes down to budget and which piece's unique character speaks to you. If you want the higher-catalog-price piece with more presence, go Specimen 4; if you prefer a lighter investment, Specimen 6 is your pick.
Why the Blue Monday drop matters
The Blue Monday collection was released as a one-off set of 19 pieces, each tied to a day of January. That means every specimen is unique and won't be reissued, which is exactly what makes these pendants collectible.
Both Specimen 4 and Specimen 6 share the same iridescent blue theme, but because they're individual pieces, each has its own distinct look. The catalog pricing already hints at a difference in how they were valued at release.
Price as a signal, not a verdict
Specimen 4 carries a catalog price of USD 123.00 (compare at USD 164.00), while Specimen 6 is priced at USD 102.75 (compare at USD 137.00). The gap is modest, but it can matter if you're shopping on a set budget.
Neither price tells you which stone is 'better'—it just reflects how the maker valued each one-off piece. Since both are sold out, the price also gives you a reference point if you're looking at the secondary market.
What we can't tell you (and why that's okay)
The catalog doesn't specify the exact gemstone type, carat weight, or dimensions for either specimen. That's a real limitation: if you need those specs to decide, you'll have to ask the seller directly or look for a piece with fuller documentation.
For a collector, the mystery can be part of the appeal—these are one-off pieces, so part of the value is their uniqueness rather than a repeatable spec sheet.
How to choose between the two
- Budget-first choice: If you want to spend less, go with Blue Monday – Specimen 6 at USD 102.75. You still get a one-off iridescent piece, just with a lower catalog price. Check if the seller offers payment plans if you want to stretch your budget.
- Higher-catalog-value choice: If you're drawn to the piece with the higher catalog price and the presence that implies, choose Blue Monday – Specimen 4 at USD 123.00. It's a bigger investment, but it may feel more substantial as a collector's item. If you're reselling later, keep the original packaging and any certificate of authenticity.
- Unique character choice: Because both are one-offs, the final decision should come down to which stone's blue and iridescence you personally find more striking. If you can see them in person or in high-res photos, trust your eye over the price tag. Ask the seller for additional photos or videos in different lighting to judge the iridescence.
