Does DiamondWave charge sales tax?

Currently, sales tax is only collected on orders shipped to addresses in New York State.

What is the quality of the DiamondWave inventory?

The DiamondWave inventory is, and always will be, of the highest value and the best quality. A good percentage our stones are mined from the Northwest Territories in Northern Canada. We do not sell any conflict diamonds. Our inventory is kept in a secure vault in New York City. We also have an office in Israel that handles some of our GIA loose stone inventory. You may occasionally find some of these stones for sale on other sites but these would only be loose stones from the GIA Registry. When we sell these stones they are pulled as quickly as possible and sent to us. This does not apply to our non-certified stones. The loose stones on our site that are not GIA are owned by DiamondWave and you find these in all our Preset Jewelry or the loose stones that say DW Select."

What is the cut grade of diamonds at DiamondWave? feels that the cut of the diamond is the most important characteristic, so this is why we hand pick every diamond we offer. Our diamond cut grades are Very Good or better. The sparkle of a diamond greatly depends on the proportions of a cut. The better the cut, the more brilliant and vivid the sparkle. *GIA diamonds come with their own certification. This is solely based on stock non-certified diamonds in our pre-set jewelry. Most of our diamonds are mined from the NW Territories and Russia.

Is there a shipping charge?

DiamondWave offers free shipping on all of our inventory. We make to order so shipping will be processed once the item is completed. Please see estimated shipping times on the detail page of the item. We can only ship to a PO BOX via United States Postal Office.

Will I be getting the quality that the diamond description states?

This is the reason why we include the original certificates with each diamond. This gives you the ability to inspect and compare, with the original certificate, to the diamond you have chosen from our inventory.

Is the quality of the diamond guaranteed?

All our diamonds are certified by gemological laboratories recognized and respected throughout the industry. All non-certified diamonds are graded by our gemologist. What is different about our diamonds? We do not sell the "off make" diamonds like your typical online jeweler or mall jewelry stores. We own and cut our own stones, they are full cuts and dazzling with fire and brilliance. Diamondwave hand picks every mounting to ensure exceptional quality. A diamond can have lower clarity and color but still shine as it is the cut of the stone that makes it sparkle.

Am I really getting a fair price and value?

The Internet gives you the opportunity to research and find the best value for a specific diamond with just a touch of a button. We urge you to compare exactly similar stones in size, shape, clarity, color, and measurements. The slightest difference causes the price to fluctuate. We are certain all of our diamonds are priced to match and beat the competition. There are no two diamonds are alike. Our inventory changes daily if you don't see a loose stone you are looking for please email our diamond consultants. 1-866-978-7801 or email

Just take a look at our inventory list and you will see a vast selection of diamonds in any shape, size, clarity and color you can imagine. If you don't see what you are looking for please email or call us. We have 100's of castings not on the site.

The DiamondWave Policy on Conflict Diamonds

At DiamondWave, we only purchase diamonds through the largest and most respected suppliers who, like us, proudly adhere to and enforce the standards established by the Kimberley Process, an international system that polices the trade of diamonds to ensure they are from sources free of conflict. Most diamonds are mined in NW Territories and Russia. The Kimberley Process, adopted into U.S. and Canadian legislation, requires manufacturers to comply with a lengthy procedure which closely tracks, ships and receives each diamond, documenting each step so as to monitor the stones’ origin. Diamonds that we offer for sale are procured from legitimate sources not involved in funding conflict and comply with the United Nations resolutions set forth by the Kimberly Process procedure. View our loose stones and find the filter for Canadian Mined Diamonds.

How to care for my jewelry?

We recommend you have your setting checked every six months to make sure the stone hasn't been knocked loose, especially if it is particularly large. Prongs bend when even the slightest knock happens. Be sure to insure your jewelry, we all know it's irreplaceable. However, it's important to have insurance just in case. Most insurance companies will include your ring under your homeowner's insurance although you can always insure it separately if you wish. Jewelry Insurance

Cold water may shrink your fingers just enough to loosen the ring from your finger. While platinum can withstand virtually any chemical, experts advise not to expose gold or silver rings to the harsh chemicals found in swimming pools and spas -- the bands can become severely discolored over time.

Playing sports. Holding anything tightly is particularly not good for a ring. As for taking your ring to the gym, lifting weights with it on can also be hazardous. Gardening. It is possible to chip your diamond or knock the setting loose while doing heavy yard work. Cleaning house. Harsh chemical soaps or cleansers can damage the ring. It's also a good idea not to wear your ring while doing the dishes.

Can you resize my ring?

Most rings can be sized up or down by one size from your local jeweler. If you would like us to resize the ring, there will be a $50 charge that includes return shipping in most cases, and you will be responsible for the cost of returning the product to us for resizing. Eternity rings cannot be resized but 1/4 size up, any higher will require the setting to be remade at additional cost. Products that are not in the size range we offer for sizing will be considered a Special Order and cannot be returned. Resizing will take approximately 5-7 business days. We highly recommend visiting your local jeweler to be properly sized. Rings that are resized run the risk of loose stones and damage to prongs, it is best to get it right the first time. Please consult us if you need resizing done or have questions.

It can be on the appraisal accompanying the item, on a hang tag or packaging component, or on the invoice or receipt for the purchase. If a pendant is sold without a chain, it may not have a stamp of metal. If an earring is sold without a back it may not have a stamp of metal. The chain and the earring back have the stamp of metal.
