Dragon Diamond

Bred by master breeder Kobayashi Naoto of Marusen Kobayashi Koi Farm, the Dragon Diamond is a striking new kawarigoi variety using the Sakai Mango Karashi crossbreed with Aragoke, and has quickly captured the attention of koi enthusiasts worldwide. This exclusive bloodline is available in both Aragoke (raised, armoured-scale) and non-Aragoke (smooth-scale) versions, offering collectors the flexibility to choose their preferred look while maintaining the bloodline’s signature traits:

Intense metallic lustre and sparkling highlights
Bold, dramatic patterns with beautiful colour depth
Strong, well-balanced body conformation
Unique “dragon-scale” presence that stands out in any pond

The non-Aragoke versions display a smoother, elegant appearance with exceptional skin quality and brilliant shine, while the Aragoke siblings offer a more textured, powerful armoured effect. A modern masterpiece from one of Japan’s respected breeders, Dragon Diamond koi combine rarity, beauty, and strong genetics — perfect for serious collectors and show enthusiasts.
