Lab-Grown Diamond Earring FAQs

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds have the same chemical, physical and optical properties as natural diamonds. They offer the same brilliance, beauty and durability while providing exceptional value.

Do lab-grown diamond earrings come with certification?

Smaller lab-grown diamonds commonly used in fine jewellery do not typically come with individual grading reports. This is standard practice in the jewellery industry and does not reflect the quality of the diamonds. Larger lab-grown diamonds may include grading reports from recognized laboratories such as IGI or GIA, where specified. At Jacob Mercari, we carefully select our lab-grown diamonds for their brilliance, beauty and quality.

What does CTW mean for diamond earrings?

CTW means “carat total weight” and refers to the combined weight of all the diamonds in the pair. For example, a 1 CTW pair of diamond studs generally contains approximately 0.50 carats in each earring.

Are your lab-grown diamond earrings made with solid gold?

Yes. Our lab-grown diamond earrings are crafted in solid 14K gold, with white and yellow gold options available depending on the design. Product pages provide the specific gold colour and diamond details for each pair.

Which style of lab-grown diamond earrings is best for everyday wear?

Diamond studs, huggies and smaller hoops are versatile choices for everyday wear. For greater impact, explore larger hoops, multi-diamond designs and statement earrings that add extra brilliance to evening and special-occasion looks.

How do I choose the right pair of diamond earrings?

Consider your personal style, preferred gold colour, setting and desired level of sparkle. Studs offer timeless simplicity, huggies sit close to the ear, hoops create a polished look, and statement designs provide greater presence. If you need help choosing, contact Jacob Mercari for personalized guidance online or at our Toronto studio.
