Diamond

All FLAWLESS DIAMOND gems use FL/IF diamonds, and we do not approve any diamond inclusions.

We are an FL diamond specialist shop without rival anywhere in the world.

As well as round brilliant cuts, we also have fancy cuts available.

For expert reports, we use GIA (America) – the world's most-trusted expert organizations.

Expert opinion numbers are entered in the girdle parts, with each and every diamond guaranteed.

All melee diamonds are taken from F color diamonds and above, and are then compared with a colorless D color master stone, with only the diamonds that are close to D color used.

Clarity conforms to VVS and above, and for all cuts we use cuts with 3EX "Heart & Cupid" gradings.

Quality

Finishing (polish)

We produce jewel frames for the finest diamonds with attention to how light enters and illuminates.

We also emphasize the fit of our rings, ensuring a remarkable sense of security when putting on one of our rings.

Comfort is also ensured by the rounding of corners in necklaces and bracelets, etc.

Diamond setting

When setting main diamonds, our skilled craftsmen carefully align each cut so as not to obscure the brilliance of the diamond, while making checks with 20x magnification.

The finest brilliance is produced by carefully arranging the girdle and table parts when seen from the side.

All of our productions are made in Japan.

We deliver advanced Japanese technology to the rest of the world.

Material

FLAWLESS DIAMOND uses original 950 platinum.

This hard platinum has a high level of purity, making it resilient against scratching and durable.

We also use 750 (18K) gold.

We have five color types available: apple green gold, yellow gold, pink gold, brown gold, and white gold.
