I've been thinking about the relative rarity of all the 1:6 scale BJDs recently, since I just got Novella, who, as a Soom Romantic Uyoo, is the rarest doll I have. Also I saw a Unoa Light Fluorite on the DOA marketplace that I want, but do not have the dough for. 🙁 Anyway, here's my spectrum of relative rarity for all the 1:6 scale BJDs:

Illusion Spirit Spirit, JAMIEshow bodies and Xagadoll Lara are so new that they haven't established distribution patterns or reputations, so I'm excluding them.

COMMON

Whether these dolls are popular or not, they're still being sold on the primary market, so they are easy to get.

• Dollmore Kidults and Cutes
• Limhwa/Eosdoll Mari and Sara
• Lumedoll Lumelights
• Soom Aren and Uyoo
• Tiny Bear Bonbon and Coco

SCARCE

These dolls appear regularly on the secondary market, so acquiring them is mostly a matter of a) patiently waiting and b) jumping on the opportunity.

• Alchemic Labo Unoa Lights
• Elfdoll Hana Angel and Devil
• Notdoll Lucy
• Soom Faery Legends
• Souldoll Metel

RARE

Dolls in this category appear on the secondary market, but much more infrequently. Expect to wait years for one to come up.

• Elfdoll Doona Soah and Ryung, as well as Hana Halloween versions
• Limhwa/Eosdoll ToYou
• Notdoll Miriam and Pandora
• Souldoll Jandi, Kimmy and Vivi

VERY RARE

I've seen dolls in this category appear on the secondary market only twice or thrice.

• Batchix Nan Sook
• Elfdoll Kathlen
• Orientdoll Joong Wol

YOU WISH!

Dolls in this category have few to zero online owner pictures and/or have appeared on the secondary market not at all or once.

• Leekeworld Jiny and Lani
• Notdoll Yohimbin
• Soom Garam, Romantic Uyoo and Sosle
• Souldoll Licht
