All items handled in our store are made of Silver925, making them less likely to cause allergies.

(Some item parts are made with K10, K14, or K18)

At nanagu, we create jewelry using pure Silver925, Silver950, K10, K14, and K18.
(If K18 coating is applied to Silver, rhodium plating or similar is not used.)

Silver925: 92.5% silver, 7.5% copper
Silver950: 95% silver, 5% copper
K10YG: 41.6% gold, 34.8% silver, 23.2% copper
K14YG: 58.33% gold, 41.66% silver/copper
K18YG: 75% gold, 25% silver/copper

【K14 Gold Filled (14KGF)】
1/20 (5%) of the total weight is 14k gold.
14k gold is bonded to a base metal (silver, brass, etc.).
*Only some parts are made with 14KGF. (Custom orders not available)

【K18 coating (18Kgp, 18k gold plating)】
At nanagu, we apply a thicker K18 coating than usual,
allowing you to enjoy the gold color for a longer time.

Please be assured that no nickel is used in the base layer of our gold-coated items.

Customers with severe metal allergies should immediately discontinue wear if an allergic reaction occurs,
and consult a dermatologist near them.

【Characteristics of Silver925】
Exposure to air, human sebum, and sweat can cause the color to change with prolonged use.

The change is unique to each individual, depending on their environment, lifestyle, and personal use.

The unique character that develops gradually will not be the same as anyone else's, nor will it ever be exactly alike.

Please enjoy the gradually changing character as you wear it.

【Gold color comparison image】

The images show the color after 2-3 months of use.
New items have a strong luster and appear to have a lighter gold color.
Over time, the luster diminishes, and the gold's chemical reaction results in the state shown in the sample photos.
Please be aware of this.

With the exception of some rings, all products are manufactured in-house at nanagu, so we can create products in your desired size.
(Size -2 to 30)

Please see below for details on ring sizes.

Sizes in 0.5 increments are also available.

We strive to flexibly accommodate precise measurements and sizes,
so please contact us via contact if you have any requests.

Additionally, nanagu carries size gauges that make it easy to measure your size.

Please see below for product care instructions.

[SILVER925 Item Care Instructions]

While silver is essentially a non-rusting material, it can tarnish or blacken due to reactions with sulfur in the air, sweat, sebum, etc.

For rings, you can restore them to their original condition by polishing them with nanagu's silver polishing cloth.

For caring for delicate chains like necklaces, the care method described in the nanagu Instagram highlight [User Guide] is recommended.

*The above care is for silver jewelry only and should not be used on gold-plated or oxidized items.
*Please be careful not to wear it when entering hot springs.
*When not in use, please wipe off any dirt and store it in an airtight container.

[18K coating item care instructions]

We recommend removing bangles and similar items when bathing.

As K18 coating is vulnerable to friction and moisture, we recommend removing it during household chores and sleep. By handling it carefully on a daily basis, you can maintain its shine for a long time.

If you notice any dirt or tarnish, please wipe it off with a soft cloth and store it in a storage bag.

Do not vigorously polish with a silver polishing cloth, as this may cause peeling.
