For Surprise Proposals

Let our Experts Help You

Contact us or visit our showroom and show us photos of your future fiancées hands. One of our experienced team members will be able to estimate the ring size.

It is not an easy task but after years of experience our team is great at it. It will always be recommended to suggest a slightly bigger size so that it is guaranteed to fit on the proposal day. Once she has said yes, she can always come to one of our Novita showrooms and have her ring resized. Novita offers one free resize with every purchase of an engagement ring as we know the importance of getting that perfect fit.

If there is difficulty visiting a jewellery store or our showroom, the next best thing is to order our free ring sizer.

TIP: When using our free ring sizer or any other ring sizer, please make sure it is tight. Engagement rings are meant to be tight and hard to take off.

FAQ'S

• Are Lab Grown Diamonds Real?

Yes, lab grown diamonds are indeed real diamonds. They are created through the same chemical and physical processes that occur naturally inside the Earth, but in a controlled laboratory setting. A starter seed of a diamond crystal is gradually enlarged by depositing more carbon atoms on it. Lab made diamonds are chemically, physically, and optically identical to natural diamonds and are scientifically validated as real diamonds. Renowned diamond authorities like IGI and GIA grade man made diamonds using the same criteria as they do for mined diamonds.

• How Much Can You Save with a Lab Diamond?

The cost of lab created diamonds is significantly lower than that of mined diamonds. The exact price difference varies based on factors like size, quality, and type, but on average, lab diamonds are about 75% less expensive. This is primarily because the cost of producing rough lab diamonds is much lower than extracting natural diamonds. However, the subsequent processes such as cutting, polishing, certification, shipping, and insurance are the same for both. For example, a £10,000 mined diamond could cost around £2,500 if it’s lab grown.

• Do Lab Diamonds Test as Real Diamonds?

Yes, lab diamonds test as real diamonds. Using a diamond tester, lab created diamonds will show the same properties and characteristics as natural diamonds due to their identical chemical, physical, and optical makeup. This includes hardness, refractive index, and thermal conductivity and other properties that are unique to only diamonds, both mined and man made.

• Do Lab Grown Diamonds Have Inclusions?

Like natural diamonds, most lab diamonds also contain inclusions which we explore in our lab diamonds guide. These are natural imperfections found within diamonds, regardless of their origin. Inclusions can vary, such as tiny bubbles or carbon deposits. It's rare for any diamond, lab grown or natural, to be completely flawless. Our 4Cs guide offers more insights on diamond colour, clarity, cut, and carat.

• Can Lab Diamonds Be Insured?

Absolutely, all lab grown engagement rings and jewellery can be insured. Since lab created diamonds are considered real diamonds, they can be insured in the same way as mined diamonds. Insurance policies for jewellery can vary, typically covering replacement or repair costs in cases of loss, theft, or damage. It’s crucial to thoroughly understand the terms of your insurance policy, and our lab diamond rings guide provides more comprehensive information.
