We have prepared a model in which the overall coloring is unified in a cool and luxurious silver color.
The product will be available for a limited time at Hakuhinkan TOY PARK Ginza Main Store, a long-established toy specialty store founded in 1899.

The classic heart motif, which is also used in the Sebonstar logo, is combined with a ribbon to create a design that appeals to the feminine heart. This model is unified in a cool and luxurious silver color.

Lavender quartz has a pale pinkish color. Its milky color creates a soft atmosphere.

Lavender tanzanite has a color close to violet, and its strong pleochroism gives it a different impression depending on the angle from which it is viewed.

Three diamonds complement the heart-cut gemstone.

The Mirage edition completely changes the glamorous impression of the first release and features two carefully selected lavender-colored gemstones that are cool and luxurious.
In order to faithfully reproduce the distinctive cut of Sebonstar, we had direct contact with skilled Indian craftsmen who are experts in handling gemstones, and after much trial and error, we arrived at a quality that satisfied us.
The diamonds used as side stones are carefully selected to be VS class equivalent, D to G color, H&C. VS class diamonds have good clarity and are barely visible with minute inclusions under 10x magnification, the magnification used by experts to grade diamonds.
Of the 23 grades, only stones are carefully selected, ranging from the highest D color (completely colorless and transparent) to the fourth grade G color (near colorless, with a yellowish tinge that is difficult to detect with the naked eye).
Additionally, H&C (Hearts & Cupid) is a design where the reflection of light reveals the shape of a heart and an arrow within the diamond. This design is packed with thrilling attention to detail, even in the details that are difficult to notice at first glance.
These gemstones are transformed into jewelry by skilled artisans with advanced techniques, and their skills, honed through years of experience, have made this collaboration a reality.
