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.

When purchasing a preset ring from our collection, our jewelers hand-pick the stone to ensure it has maximum brilliance.

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.

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.

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!
