Jewellers U-Treasure are the purveyors of fine jewellery for the more sophisticated otaku.

Despite being Pokemon or Star Wars themed, their items don’t look childish or garish in any way and are aimed at adult fans of these series. They’ve even brought out some stylish Pokemon wedding rings for trainers who are done adventuring solo.

They also have a very delicate and feminine line of necklaces dedicated to the ever-popular Eeveelutions, a collective term for the different Pokemon that can evolve from Eevee.

Eevee, Espeon and Umbreon were released previously (seen above among some other Pokemon), but recently Glaceon, Sylveon and Leafeon were also revealed one by one in classic 'Who's that Pokemon?' style.

The Eeveelution charms on each necklace are beautifully detailed all around.

Each Pokemon sits on a Pokeball with a jeweled centre and the colour of the jewel corresponds to the type of Pokemon it is. For example, the grass Pokemon Leafeon has a green one and the fairy type Sylveon’s is pink.

Each necklace comes in platinum 950, silver, or take your pick from white, rose or yellow gold. You'll have to be pretty serious about your love for Pokemon inspired accessories since the silver option will set you back 12,000 yen ($114) and the gold ones are much pricier at 55,000 yen ($524). Since platinum 950 is a high-grade platinum, it's even more expensive than the other options at 65,000 yen ($619).

You can buy the necklaces online on U-Treasure's website (Japanese only).
