Loose Diamonds in Ottawa

Looking for the right diamond for an engagement ring, a custom piece or an upgrade? At Noura’s Jewellery in Alta Vista Plaza, Ottawa, we source natural and lab-grown loose diamonds to your shape, size, colour, clarity and budget from our trusted suppliers, show you the details of every stone, and set your choice in our own workshop. With 17 years of experience, we help you compare stones in plain language, so you choose with confidence.

  1. CaratThe weight of the diamond. One carat is 0.2 grams.
  2. CutHow well the facets return light. It drives the sparkle.
  3. ColourFrom colourless (D) to light yellow or brown. Less colour is rarer.
  4. ClarityTiny inclusions or marks, seen under magnification.
Natural and laboratory-grown diamonds look alike but are valued very differently, so every stone is examined in person.

How finding your diamond works

  1. Tell us what you are looking for

    Shape, approximate carat weight, budget, and the setting you have in mind. A photo of a ring you love helps too.

  2. We search our trusted suppliers

    We put together a shortlist that fits your brief, with the grading details of each stone.

  3. Compare the options with us

    Visit the shop and we will explain the differences between the stones, so the choice is clear.

  4. Set in our own workshop

    Your diamond is set in a ring you choose, or in a custom engagement ring designed with you.

Shapes we source

Round, oval, cushion, emerald, pear, marquise, princess, radiant, Asscher and heart. Each shape returns light differently and suits different settings; we will show you how they compare at the size you have in mind.

Natural or lab-grown?

Both are real diamonds, with the same sparkle and hardness. Natural diamonds formed in the earth over millions of years; lab-grown diamonds are made in a controlled environment and usually cost less for the same size and quality. Their long-term resale value is also very different. We explain both honestly, so you can decide what matters most to you.
