Common Questions

Our standard production time ranges between 12 to 15 days, although this will largely depend on the complexity of the piece in question. This is why we ask our clients for an ideal deadline, which is how we develop our timetables. We stress that our clients anticipate our production dates when creating an ideal turnaround time.

What if I don't know the ring size? That’s not a problem. We can send you a ring sizer to try on before we start the job.

No, but we do need to make some clarifications. If your piece of jewelry is unique to you and has a very distinctive design, then we will not copy the elements that have made it your own. While we retain copyright ownership on all works we create, as a courtesy we don't exactly copy custom designs that we’ve made for a customer. If you are only making a version of one of our regular designs, then yes, we can still make it. If your design is generic - that is, not specific - we cannot allow that design to be removed from our repertoire.

For legal reasons, we do not copy other designer's work. But if you would like to have a design created in a similar motif or feeling as the designer piece, we can certainly create a new piece that meets your expectations. This is considered to be designer-inspired jewelry, which is one of our specialties.

No. We retain copyright ownership on everything we make.

We are more than happy to set your heirloom diamonds or gemstones in your custom design piece. However, it’s important to note that we are not responsible if the stone breaks during setting. To help prevent this, we subject stones to inspection for chips, nicks, and broken parts. This helps ensure that your stone is ready for the setting process. If you’re ready to take those old pieces in the bottom of your jewelry box and turn them into something new and exciting, we can do exactly that.

Custom designed jewelry can cost much less than you might expect. Our custom designs tend to be priced equivalent or cheaper than comparable mass-manufactured designs. Upon placing your order for your one-of-a-kind jewelry, a $250 deposit will be charged. This fee is not an extra cost, as it is already included in the quote we provide you.

Yes. To create a band that exactly matches your engagement ring, we must have access to the engagement ring. If you’d like, you can have your local jeweler take out the center stone before submitting your engagement ring to us.

We work with a wide variety of precious metals, including 14k white, yellow and rose gold, 18k white, yellow and rose gold, platinum, and palladium.

New models, custom designs and special orders are non-returnable. To meet your expectations, we start manufacturing your ring upon your CAD rendering image approval. We also send you the wax of your design before we cast it.

Comfort fit is a slight rounded edge inside your wedding band. You can find more information about comfort fit in our <a href="">glossary</a>. Almost all of our wedding bands have comfort fit. Comfort fit doesn’t affect the ring size you need to choose. You don’t need to go up with ring size because the wedding band is comfort fitted.

Yes! We do free engraving for all wedding bands. You can add your engraving text to your order on the item page, and also choose the <a href="">font style</a> you want. We also have special fonts like Hebrew and Russian, and special character heart symbol. For heart symbol, please contact us after placing the order. Some styles, such as diamond wedding bands with all around stones, cannot be engraved.

We have a variety of finish options for our wedding bands. Please check our <a href="">finish samples</a>. Each ring style has certain finish options that would go well with the style. If you can’t see the finish choice you want as an option for a specific band, please contact our <a href="">customer service</a>.

If your wedding band doesn’t fit, you can send it back to us for free resizing up to one size difference first time in 30 days, or you can get an exchange if the size difference is bigger. If you don’t know your finger size, we can mail you a plastic sizer for free in US. If you are in a hurry, we recommend visiting a local jewelry store to find out your finger size. We also have a finger size chart paper, however please be advised that paper charts are not as accurate as a plastic or metal sizer. Another factor you should take into consideration is that if you get your finger sized with a narrow plastic or metal sizer, and if you’d like to purchase a wide band (7mm or up), you should go quarter or half size larger, so the band can pass through your knuckle easily.

We have a <a href="">ring size conversion chart</a> that shows not only the conversions but also dimensions of all ring sizes.

This is more common a case than you think. If you love gold and only want to wear gold jewelry, we recommend only 18K gold, which has less nickel content. However the best solution is to avoid gold and go for allergy-free metals: platinum and palladium. Both of these are 95% pure precious metal, and they don’t give you any allergic reaction. Another advantage of platinum and palladium is that they don’t require periodical re-rhodiuming like white gold does, as these are naturally white metals.

Possibly. Please bear in mind that unless otherwise specified, all engravings are done inside the ring. However you can request an outside engraving depending on the ring style. If the ring is plain, or has just a little decoration outside, we may be able to engrave the outside of the band. Please contact our <a href="">customer service</a>.

All wedding bands manufactured by are solid precious band. We do not carry hollow products. Approximate gram weights are listed for each item on the item page to give you an idea about the weight of the final ring too.

Yes. We can do any customization to our band stones. Depending on the size and shape of the stone, you can request black diamonds or your favorite gem stone be set on the ring instead of white diamonds. For a price quote, please contact our <a href="">customer service</a>.

Yes! Almost all rings that are available in platinum or palladium, can be finished as two-tone combined with yellow gold. For a price quote for the custom ring, please contact our <a href="">customer service</a>.

Yes. On the wedding band set item page, there is a tab that reads "single ring" right under the product description. If you click that, you will see the link for single ring page. Alternatively, you can search for the same product number without the "HH-" at the beginning. <br> If there is no single item shown on the page, please contact <a href="">customer service</a>. We will help you place your order.

Simply put, a karat is the unit of measurement used to indicate the purity of gold. This is because gold is in fact a mixture of gold and other metals. Pure gold is 24-karat (24K), 18-karat gold is 75% pure, and so on. Carat is a term used to measure the weight of a diamond, e.g. 1-carat, 2-carat, and so on. One carat is equal to 0.2 grams. Please refer to our Education tab for more detailed information.

Diamonds are graded and priced according to what is universally referred to as the '4Cs'. The 4C's include Cut, Color, Clarity and Carat weight. Each is a description of the various characteristics of a diamond. For example, Cut refers to the shape of the diamond, which affects its fire and brilliance. Color refers to the amount of color in the diamond (the less color a diamond has, the more valuable it is, all other factors being equal). Clarity describes the number of natural blemishes and inclusions a diamond has, and Carat Weight is simply a measurement of the diamond's weight (not its size). Please refer to our Education tab for more diamond details.

Simply put, 18 Karat gold is more pure, meaning it contains a higher percentage of gold. Pure gold is 24-Karat (24K), 18-Karat gold is 75% pure, and so on. Please refer to our Education section for more details regarding gold.

Jewelry that has a number and a 'K', this denotes its Karat amount, or the purity of the gold in the piece. Gold is actually a mixture of gold and other metals. Pure gold, 100%, is 24-karat (24K) , 18-karat gold is 75% pure, and so on. Please refer to our Education tab for more details regarding jewelry terms.

There are many factors that can affect the value of gold jewelry. Since gold is sold by weight, heavier pieces can be more costly than lighter ones.

General guidelines for caring for and cleaning your diamonds include the following: Avoid wearing your diamonds while doing housework, yard work or any other kind of rough work. Also, when doing household chores, never allow your jewelry to come into contact with chlorine bleach. Even though a diamond is extremely durable, a hard blow could chip it. General preventative measures will ensure your diamond remains true to it's glory. To clean your diamonds you may choose to do the following: 1) In a bowl of warm, sudsy water with a bit of any mild liquid detergent. Brush the pieces with a soft brush, then transfer them to a wire or tea strainer and rinse with warm water. Pat dry with a soft lint-free cloth. 2) Many choose to use an Ultrasonic jewelry cleaner as they work quite well also.

The following guidelines will help ensure the beauty of your jewelry remains looking new: 1) Avoid contact with bleach, soap, perfume, cosmetics, hairsprays, etc. 2) Take your jewelry off at night and store it in a jewelry box with compartments that keep pieces from rubbing against each other. 3) Clean your gold jewelry in a bowl of warm, sudsy water with a bit of any mild liquid detergent. Brush the jewelry with a soft brush until you have created a lather around it. With the jewelry on a plastic or metal strainer, rinse off with warm water. Do not clean your jewelry over the sink to prevent it from falling down the drain. Pat your jewelry dry with a soft, lint-free cloth. is dedicated to supporting the Kimberley Process and to ensuring that none of the diamonds we buy are conflict diamonds. We believe that financing violence is unacceptable to our business and we take this issue very seriously. We take extreme pride in our ability to purchase stones directly from cutters allows us to be extremely cautious and selective with our sources. We only buy from sources that adhere to the same uncompromising philosophy. Our diligence in doing business only with vendors who comply with the KPCS is our assurance, and promise to you as our customer, that we do not conduct business with, nor do we sell any product comprised of conflict diamonds.

Certified diamonds have had their quality examined and confirmed by a major laboratory. You will receive the certificate from a reputable laboratory and have the confidence of knowing that the quality of the diamond is accurate to its representation. Uncertified diamonds have not been graded by a major lab, and therefore, do not offer the security and accuracy that its counterpart does. Certified diamonds are also significantly more valuable than comparable uncertified diamond.

"Eye-Clean" is a term used to describe a diamond that is clean to an unaided eye in a face-up position from a distance of 8 to 10 inches. Diamonds of VS2 or higher in quality will always be eye-clean. Diamonds of Si1, Si2 and I1 need to be visually inspected to determine whether any inclusions are visible from the top. We can inspect any diamond at no charge.

We ship every loose diamond and diamond engagement ring with an independent GIA report. This report can be examined by a qualified gemologist and compared against the unique characteristics of your diamond.

No. 25Karats only sells diamonds that are 100% natural and untreated. The Gemological Institute of America (GIA) will not issue grading reports on diamonds that have been treated or enhanced, so purchasing our diamonds - which are all GIA certified -- is another guarantee that your diamond is natural.

Physically, there is no difference between certified and uncertified diamonds. The certification doesn't add anything to diamond itself. What a certification does is, it gives legal assurance to diamond's physical appearance. The certified diamond comes with grading report from the independent labs like GIA and EGL USA. Grading report puts the diamond information into a very important paper and with this report you are not only getting beauty but also proof of qualities. Uncertified diamonds are not necessarily bad quality diamonds, but they are open to an argument for their 4Cs because they are not backed by a grading report. Their qualities are based on the word of the seller. We,, would like you to by your center stone with peace of mind. Therefore the center stones we carry come with a grading report by an independent, reputable gem lab (GIA, EGL USA...).

Palladium is new in jewelry making compared to gold, but historically it is not so new. Palladium was discovered in 1803 and jewelers started using palladium in 1939. This shows clearly that this metal has been in jewelry making for awhile, and has long time experience with palladium. Palladium used in our jewelry is mined in North America, so that makes it an American metal.

It is no secret, platinum is more expensive than gold products. Even at times when per ounce price of platinum is very close to gold in the metal market, platinum rings are more expensive even for the same model rings. There are three major elements that play a role in that price difference. The first one is, platinum is sold as a pure metal, a.k.a 950 platinum, which is 95% pure precious metal. Gold on the other hand is sold as an alloy: a combination metal of certain percentage gold and other metals. Second, platinum is almost twice as heavy as 14k gold. That also has a huge effect in pricing. The third is the labor. Casting and working with platinum on the jeweler's bench is more costly than other precious metals, and this also affects the pricing for the platinum.

The best answer to this question is to talk to a specialist. It is very difficult to pick a matching band for your engagement ring just by looking at the pictures. Talking to a customer service representative will make the process a lot easier for you. They might offer you a band that already exist after seeing your engagement ring's picture or inform you about how to make a new one from scratch.

Enhancer ring name itself is pretty much self explanatory. It enhances the look of an existing engagement ring. Enhancer rings are mostly used for solitaires. Instead of setting diamonds on a plain solitaire shank, solitaire ring is updated with matching enhancer ring. There are different styles available: jackets (engagement ring inserted in), guard rings (side diamonds are extended and wraps over the solitaire's shank), wrap matching bands, etc.

There are all different types of setting. Their popularity changes with fashion, model and the most importantly personal choice. Here are some the most common setting types we all used to seeing on jewelry web sides or in jewelry retail stores. They are pave set, shared prong set, double prong set, channel set, burnish set, basket setting and bead set.

Mill grain is design element that applied to jewelry such as engagement rings, wedding bands or pendants. Jeweler applies an engraving tool (mill grain wheel) on the edges to give it a look similar to a coin edge.

Yes, please contact us with the style of the engagement ring(s) desired. We can cast and build most of our engagement styles in two tone gold.

Alloy is all the metals that are combined with the precious metal to make it harder, hence easier to work with during production. Our gold alloy contains nickel, silver, copper, and traces of other metals. Our palladium alloy contains ruthenium, and our platinum alloy contains iridium. Please note that pure gold percentage depends on gold karat. All platinum and palladium jewelry we manufacture are rated 950, or 95% pure precious metal.

Most of our engagement rings are sold without the center stone. Center stone can be purchased separately, and we finish the ring with center stone for you if you do. However you can buy only the ring itself without the center stone. In that case, we finish the ring for your center stone measurements. Any side stones on the settings come with the ring, and we do not sell our settings without side diamonds.
