Each GAGAN product is handmade, so no two are exactly alike.
Please understand that the surfaces are not machine-polished, and some items are designed to feature a rough texture, which is intentional and not an oversight in polishing.

While we take great care in ensuring the durability of our products, some pieces prioritize delicate designs. Therefore, repair fees will apply for issues not due to initial defects.

Additionally, products incorporating chains or other parts may exhibit individual variations of approximately 5mm in shape and other aspects. Please understand that these are characteristics of the product and part of its handmade charm.

▪️18K / 10K / Platinum
These materials are resistant to tarnishing caused by sebum and sweat. However, discolouration may occur if sebum and sweat react with the air and oxidize.
After wearing jewelry for an extended period, rinse it lightly with water and wipe it with a soft cloth. When not in use, store it in a jewelry box or airtight bag.
Do not use abrasives. If you are concerned about dirt, soak the jewelry in lukewarm water with a neutral detergent dissolved in it for 15 to 30 minutes.
*Please note that depending on the properties of the hot spring water, discolouration may occur.

▪️18kgp
18kgp = 18k gold-plated product. As the base metal is different, strong polishing with a silver polishing cloth may cause the colour to fade and peel off.
If you are concerned about dirt or dullness, wipe it with a soft cloth and store it in a protective pouch.

▪️Silver925
Silver is generally a rust-resistant material, but it may tarnish or blacken due to reactions with sulfur in the air, sweat, or sebum.
While polishing with a silver cloth can restore its original shine, liquid silver polish is recommended for delicate designs or fine chains like necklaces.
*Do not use the above care methods on gold-plated or oxidized items; they are for silver accessories only.
*Please be careful not to wear silver jewelry when entering hot springs.
*When not in use, wipe off any dirt and store it in an airtight container.

▪️Brass
To enjoy the characteristics of the material, it will develop a tasteful, antique-like colour over time.
Brass is vulnerable to water, and if left wet, it can cause verdigris (a type of rust). Therefore, wipe it with a soft cloth and store it in an airtight bag when not in use.

Natural stones will be shipped randomly, so while you can select your desired type, we cannot accommodate requests regarding variations in color intensity or patterns due to individual differences.

The materials available vary by item.
For details, please check the [MATERIAL] section on each product page.

Please note that we cannot accept orders for materials not listed on the product page.

For products displaying [ENGRAVING], you can select "select" to choose your text and font.
You can specify up to 6 alphanumeric characters (including half-width spaces) for the text.

*Hiragana, Katakana, Kanji, and symbols cannot be selected.
*Engraving will be placed on the inside of the ring at the 3 o'clock position.

▪️jwdiye/jwdiye single
Due to the structure of the hook, loosening may occur during use depending on how force is applied during attachment and detachment.
Please try to make fine adjustments by gently tightening it with pliers or other tools, with a soft cloth in between.
If you find it difficult to adjust yourself or are concerned, we can also adjust it for you in our store.

▪️drip nc single/drip bc
Please adjust the hook part little by little each time it loosens.
Repeatedly opening and closing beyond the design's tolerance may cause the metal to harden and break, so please keep the opening and closing of the hook part to a minimum when attaching and detaching.

Regarding hinged earrings, the clasp may drop down, causing the closure to become loose.
You can adjust this yourself by gently pushing up the post, so please try it.

*Since the clasp is also made of silver925, please adjust it with minimal force.

GAGAN stocks rings in existing sizes from 1 to 20.
If you would like a size or half size other than those listed on each product page, please select [FREE] size and enter your desired size in the remarks column when placing your order.

Please note that due to design constraints, some products may be difficult to produce in sizes other than those listed, so please contact us in advance if you have any concerns.

*If you are unsure of your ring size, please refer to the Sizing guide in the footer menu.
*Returns and exchanges are not accepted after purchase.

All items are unisex.
While we recommend choosing a size based on your body type and desired fit, depending on the design, on average, women tend to choose S size and men tend to choose M size.

The total length measurement taken flat is listed on each product page, so please use a string or ribbon to check the size before purchasing.

For products using chains or parts, due to the nature of their shape and manufacturing process, there may be individual differences of approximately 5mm.
Please understand this as a characteristic of the product and the unique texture of handmade items.

*Returns and exchanges after purchase are not accepted.

You can specify a delivery date and time on the order screen under "Delivery Date and Time Specification."
