We offer a variety of stone types for our rings and fine jewelry. Each item is is clearly labeled within the description to tell you what stone type(s) are included for that item. Please note we offer a large variety of natural diamonds, clarity enhanced natural diamonds, lab-grown diamonds and moissanite.

Ideal cut diamonds reflect the light that enters the diamond in a precise manner to maximize sparkle. This is achieved by cutting the diamond with specific crown and pavilion angles. Ideal cut diamonds from Mikado must also have the highest grades (excellent) for polish and symmetry.

Ideal cuts are some of the rarest and are offered through the Prestige Engagement Collection; however, a request for an ideal cut in any of our ring styles can be accommodated upon request.

We specialize in clarity enhanced diamonds. These are natural diamonds mined from the earth. After the diamond is cut and polished, it undergoes another special treatment which removes some of the visible inclusions. It allows you to receive a very high clarity diamond for only a fraction of the price of an untreated counterpart.

With our decades of experience in this field, you can have complete confidence in the quality of our product and the professional expertise we offer. The unique enhancement process we use is invisible to the untrained eye, the diamond remains exactly the same, exactly as strong and durable, and has the exact same carat weight. You will also receive a lifetime warranty on the diamond's enhancement, guaranteeing your diamond will remain as beautiful for as long as you own it!

The proprietary clarity enhancement process we use is extremely durable. The treatment formula has been perfected for over 20 years over many thousands of diamonds.

The enhancement is not affected by time or by regular jewelry wear and tear. No special care needs to be taken. The diamond is just as strong and durable as any other diamond.

In any case, we provide a lifetime guarantee with every enhanced diamond we sell. Should anything ever happen to the enhancement, you are also completely protected. We will re-apply the enhancement free of charge if ever requested to do so.

We recommend cleaning your jewelry at home with a soft dry cloth. Abrasive chemicals such as chlorine and ammonia should be avoided as they could damage the setting.

If cleaned professionally by a jeweler, ultrasonic cleaning, steam cleaning or boiling water is perfectly safe and will not affect the enhancement.

There are three ways the enhancement could potentially be damaged and simple precautions can be taken to prevent all three.

Fire – Temperatures above 572 degrees Fahrenheit for an extended period of time. When having work performed by a jeweler you should let them know the diamond is clarity enhanced. They can still perform all the work they would normally do while taking precautions to avoid heating the diamond. If the diamond is damaged by fire, the enhancement can be re-applied easily under the Lifetime Warranty.

Exposure to boiling acid – This one is easily avoided by not putting your ring finger in boiling acid. Again, if the enhancement is damaged by boiling acid it can be re-applied under warranty. Unfortunately, we will not be able to fix your hand if you place it in boiling acid so please don’t do this.

Re-cutting – If the diamond was ever cut in the future it could compromise the enhancement.

Any returned merchandise should be in the original unused condition, include the original packaging, certification and/or appraisal. When your order includes a laboratory grading report, we ship it to you with the accompanying diamond grading report (also called a diamond certificate). No returns will be accepted without the original diamond grading report that came with the order or if it has been more than 30 days. Items purchased on layaway or with Affirm financing are subject to a restocking fee. The specific terms are disclosed in the checkout agreements based on the item(s) you are purchasing. Mikado Diamonds is not responsible for lost, stolen or damaged jewelry while in your possession. It is recommended to get the article insured as soon as it is received. Your purchase may be eligible for a free insurance appraisal which can be used to easily obtain insurance on your item. No returns will be accepted after 30 days from when we ship your order. No exceptions.

We have partnered with several strategic diamond and jewelry manufactures to bring the best value to our customers. We currently offer diamonds with GIA, AGS, IGI, AGI, EGL, IGL and GIE certifications. When certification is not included we will provide an appraisal for insurance purposes. The certification, if available, will be listed for each individual diamond or ring.

All of our clarity enhanced diamonds are graded off of the IGL or EGL International scale unless otherwise specified. This does not mean each diamond will come with an IGL or EGL certificate but that this is the scale on which we grade our diamonds. GIA does not grade clarity enhanced diamonds.

Please see the Education Center section for additional information about Cut, Color, Clarity and Carat.

An appraisal is a written estimate of the approximate retail replacement value of an item described. They can be used for insurance purposes and should be updated every 5 years.
