If you have any questions call us toll free at (800) 766-7119.

Every Certified-Plus Diamond is carefully examined in our Gemological Laboratory before it is shown or delivered.

Our Sarin proportion analyzer and the Gran Colorimeter provide important details about your selected diamond that is not shown on the G.I.A. diamond quality report.

The accurate evaluation of color, clarity and a diamond's cut proportions are essential to the assurance of your diamond's quality.

Few jewelers or online diamond brokers provide you with this high standard of qualified service.

At Droste's, you will find comfort in knowing that the diamond or jewelry you purchase has been carefully examined to meet the highest standard of excellence and quality.
