No need to worry! Determining the correct ring size can be challenging, especially when planning a surprise proposal. To alleviate any sizing concerns, your initial resize is complimentary if you return the ring within 30 days. The resizing process typically takes around 10-15 working days from the date we receive your item. It's important to be aware that specific designs, like full-set diamond eternity rings, are not resizable. In such cases, they will either be exchanged or remade to ensure a perfect fit. We suggest requesting a ring sizer or going to the local jewellery store and having your finger measured there.

Depending upon the payment method used, it can take 8-10 working days for the refund to appear on your bank/card statement. Please refer to our Returns Policy for more information.

Like natural diamonds, lab grown diamonds are also evaluated based on the 4Cs established by the Gemological Institute of America (GIA): carat weight, color, clarity, and cut. For your peace of mind, all our diamonds above 0.5ct come with an official IGI certificate. Carat Weight - The term carat weight pertains to the mass of a diamond, where one carat is equivalent to 0.2 grams. Color - The color grading system spans from D (colorless) to Z light yellow or brown hues). The grades increase in value as they go higher. Clarity - Diamond clarity indicates the level of imperfections or inclusions, both internally and externally. Cut - "Cut" refers to a diamond's symmetry, proportions, and polish, which greatly influence its brilliance. For larger diamonds, an almost colorless or colorless hue, exceptional clarity, and a precise cut is recommended to achieve the best possible shine.
