You might find it frustrating to figure out the ring size for you or your fiancée, especially if you want to keep the proposal plans a surprise.

Best lab grown diamond rings UK by Novita

For Surprise Proposals

Let our Experts Help You

Our team will measure your hands professionally! Visit us at one of our showrooms for the best and most accurate results. Alternatively, you can send us pictures of your or your future fiancée’s hands if you are unable to physically visit us. Using photos, our team members can estimate the ring size, which isn’t easy, but we are able to do so very well and end up close to the real size.

Because fingers naturally expand when active, we always recommend our customers get a slightly larger size so the ring will fit on the proposal day. Nevertheless, if the ring doesn’t fit perfectly after she says yes, she can always get the ring resized at any of our NOVITA showrooms. Because we understand how important it is to have a perfect fit, NOVITA offers a free resizing with the purchase of every engagement ring (valid for a year after purchase).

If visiting our showroom or any other jewellery store is difficult for you, you can order our free ring sizer instead.

TIP: It is important that our free ring sizer, or any other ring sizer, fits tight on your finger for a secure and comfortable fit. Engagement rings should fit snugly and be difficult to remove without being uncomfortable.

Download Our Ring Sizer

Download and print our “How to find your ring size guide” for an easy way to measure your or your fiancé’s ring size. Included in the guide are two easy ways to measure a ring’s size.
This kit comes with a ruler that can be easily cut out and used directly to measure your ring finger. Follow the included instructions, and you will soon know what size you need.
It is also possible to use a current ring, not the finger, to measure the ring size. The first step is to remove one of the rings you or she wears, but make sure it is not being worn on the thumb or pinkie finger. Next, you can find out the size of the ring by matching it with printed circles. This method is best for those who already wear a well-worn and comfortable ring.
Alternatively, if you prefer to get a more accurate measurement, you can order a free ring sizer kit. You can expect to receive your ring sizer within 1-4 days of ordering in New Zealand; however, if you are ordering from outside New Zealand, please allow up to 14 days. To order one, simply click the button below, fill in your details, and we will ship it right to your door.

Trying on the rings in person is the best way by far to make sure the ring size is perfect if your partner is involved in the engagement. For a comfortable and secure ring, come to any of our showrooms, and our staff will be more than happy to accurately measure your finger size. Alternatively, you can visit a local jewellery store to get your finger measured if your neighbourhood does not have a NOVITA showroom yet.

In New Zealand, rings are typically sized M, N, but if your partner’s finger size is smaller or thinner than average, we recommend a J, K, or L size, and if their finger size is larger, we recommend an O, P, or Q size.

Please remember that your first resize is free, so there is no need to stress if you get it wrong the first time.

FAQ'S

• Are lab grown diamonds real?

Without question, lab grown diamonds are genuine diamonds. They are produced using the same chemical and physical processes found in nature, but under controlled laboratory conditions, where a diamond crystal seed is gradually expanded with additional carbon atoms. From a scientific standpoint, lab grown diamonds are chemically, physically, and optically identical to mined diamonds, and are thus considered authentic diamonds. The leading diamond authorities, IGI and GIA, evaluate lab made diamonds according to the same scale and methodology used to grade mined diamonds, further confirming their legitimacy.

• How much cheaper are lab diamonds?

Lab grown diamonds are consistently more affordable than diamonds mined from the earth. The extent of the price difference is influenced by several factors such as the diamond's size, quality, and specific type, but on average, lab made diamonds in New Zealand can cost around 75% less than mined diamonds. This is due to the lower cost of producing rough lab grown diamonds compared to the expense of mining and extracting rough mined diamonds from the earth. However, both lab grown and mined diamonds must undergo the same processes, including cutting, polishing, and certification, to become retail-ready, regardless of their origin. For instance, you can save significantly by opting for a lab grown diamond over a mined diamond. A mined diamond may cost $10,000, while an equivalent lab grown diamond might only cost $2,500.

• Do lab diamonds test as diamonds?

Lab grown and mined diamonds are indistinguishable from each other. The same testing methods used to examine mined diamonds are also applied to lab grown diamonds. Both diamonds are chemically, physically, and optically identical, and display the same attributes and features when tested. These characteristics include hardness, refractive index, thermal conductivity, and other distinguishing characteristics of diamonds, regardless of whether they are mined or man made.

• Do lab grown diamonds have inclusions?

Inclusions can be found in both lab grown and mined diamonds. These are mined flaws that are typically present within diamonds. These imperfections come in various forms, including small bubbles or carbon deposits trapped inside the diamond during its formation. In the same way as mined diamonds, most lab grown diamonds have inclusions, and only a few become entirely flawless. For further details on diamond clarity, please refer to our 4Cs guide.

• Can I insure lab grown diamond rings?

Yes you can, it’s the same as insuring a mined diamond. You can obtain insurance for your lab grown diamond in NZ through almost any insurance as long as they insure jewellery. Typically, your insurance policy will cover the cost of replacing or repairing your ring in the event of loss, theft, or damage. It is important to read the terms of your insurance policy carefully to understand what is and is not covered.
