Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually does mean how well a diamond’s facets interact with light. Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry and polish deliver the magnificent return of light only possible in a diamond.
Achieving the best cut for a diamond reflects in the stone’s final beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyze. To determine the cut grade of the standard round brilliant diamond – the shape that dominates the majority of diamond jewelry – GIA calculates the proportions of those facets that influence the diamond’s face-up appearance. These proportions allow GIA to evaluate what the best cut for a diamond is, by studying how successfully a diamond interacts with light to create desirable visual effects, such as:
GIA’s diamond cut grade also takes into account the design and craftsmanship of the diamond, including its weight relative to its diameter, its girdle thickness (which affects its durability), the symmetry of its facet arrangement, and the quality of polish on those facets.
The GIA Diamond Cut Scale for standard round brilliant diamonds in the D-to-Z diamond color range contains 5 grades ranging from Excellent to Poor and is the definitive scale for classifying diamond cuts.
The distance from the bottom of the girdle to the culet is the pavilion depth. A pavilion depth that’s too shallow or too deep will allow light to escape from the side of the stone or leak out of the bottom. A well-cut diamond will direct more light through the crown.
“Scott is extremely gifted and knowledgeable at what he does. I was reassured that any questions or concerns I did have he would have the expertise to handle them. Despite 1 mishap that occurred that was not his fault, Scott quickly and professionally dealt with the situation that ended up giving me an even better deal. I would highly recommend getting a ring made here.”
“Culet made my fiancés ring dreams come true this weekend! From the initial consult, right the way through to the proposal, Scott was there in support. The whole experience was awesome. I'm so glad I went bespoke. We'd gone into a few hight street street Jewellers in the past and nothing compares to the quality and price, It's just not possible. I would 110% recommend Culet and we both couldn't thank them enough.”
“Couldn’t have asked for a better experience. Scott’s support/expertise are second to none and made what is generally a pretty overwhelming time, simple. From putting a design on paper, to choosing a diamond to the finished product, I found Scott very professional but also someone I could have a good laugh with. I would highly recommend Scott to all - thanks mate, appreciate all your help.”
“Would highly recommend. From start till finish Scott helped every step of the way and understood what I was after for my now fiancé. Will be back to sort wedding bands and more.”
“I had a great experience with Scott at Culet. I did plenty of research and shopped around before going with Scott. His prices were competitive and his service was exceptional. Right from the start he gave me the confidence that he knew what he was doing and had the experience to help me through the process to get the result that I wanted. I can't recommend it enough, I wouldn't change a thing.”
“Top notch bespoke jeweller. My partner was more than ecstatic!!”
“Scott at Culet Jewellery is great at what he does and you can see why he has such positive reviews. I recently purchased an engagement ring and the whole process was fantastic. He is extremely personable, listens and genuinely cares about getting the best outcome for you. Best of all the quality of the diamond (and engagement ring) was excellent and my fiancee and I couldn't be happier with the results. He is transparent and provides detailed videos of the diamond so you know what you are getting. If you are in the market for a ring I would definitely pop in to see him, I did the rounds and I don't believe you will find anyone better, you won't be disappointed.”
“I searched throughout the Auckland and Bay of Plenty areas for a jeweller that I felt comfortable handcrafting my now fiancés engagement ring and then we found Scott. He was always contactable whether over an email, in person or via phone, very personable and just a decent guy. Bespoke handcrafted jewellery to the highest standard. I can’t recommend Scott highly enough for any future requirements as we will be heading back to see Scott for our wedding bands as his service was faultless and like no other. This was an experience and not just another jeweller.”
“Bespoke is the only way to go! I put Scottie under pressure to nail a unique design, and the process was so smooth that it’s still hard to believe now. My fiancé got the ring of her dreams! The only part that was difficult was doing the sly collection at a BP gas station without her seeing, and then hiding it for 3 weeks in a motorhome, but hey... what an absolute WIN! 💎 It’s simple: Go directly to Culet, everyone. 🙏🏻”
“The service from these guys is amazing. Scotty made an amazing ring for me and I'm stoked. You'd be crazy to go anywhere else.”
“I was referred to Scott at Culet by a friend of mine a few years ago and have never looked back. We started with a bespoke gold chain and ended up with my partners engagement ring with many items in-between. The personal service coupled with Scotts attention to detail and great feedback made the whole process easy and highly enjoyable. I would not hesitate to recommend Culet for any jewelry needs.”
“Scott at Culet was a pleasure to deal with. Great communication and great knowledge. Guided me through the process with his expertise and everything went smoothly. Would highly recommend.”
“I recently worked with Scotty at Culet to design an engagement ring for my partner. I was referred to him by a friend of mine. Absolutely brilliant service, I used to work in the hospitality sector and I really appreciate genuine service. He gave me some honest feedback and advice, couldn't have been an easier process. I walked out of there thinking that i didn't want to work with anyone else. If you are wanting anything made or any advice, he is the guy to go see.”
“We got our rings designed and created by Scott from Culet and he was amazing to work with. We would 100% recommend him. What I find separated Scott from other jewellers is that he listened to us. He didn't have some preconceived idea about what rings we should have - he listened carefully when we told him what we want and then he brought that vision to life. When it comes to jewellery this is what matters most. What also matters is quality and his is the best. I am very satisfied with the service and product he provided - he was prompt, efficient and very invested in getting us the best rings possible. Thanks Scott!”
“Culet couldn’t have done a more perfect job of creating my now finances dream engagement ring – four months down the track and she still can’t stop staring at it! Both the diamonds and construction are incredible and the attention to detail is very impressive. Scott has provided incredible service from start to finish, and this has continued post ring purchase with Culet’s fantastic ring cleaning service - we can’t wait to create more jewellery with Scott and the Culet team.”
“A remarkable experience. The whole process from an idea to an exquisite custom made engagement ring then our wedding rings was made so easy. Scotty's experience and customer service is second to none. Working to my budget and delivery on time. I have since sent all my friends his way and they all sing Culet's praises. Highly recommend to anyone wanting to spoil their significant other in the best way possible.”
“The journey from ideas to final products is key! Culet helped me and my fiance create a bespoke jewellery piece that we're in love with. Scotty made the process comfortable and easy, whilst ensuring the best product was the main focus for my budget!”
“was very professional and discrete, helped me through the design and choosing the right diamond (I really went in with no idea how the process was going to work). Very easy, great deal and the service afterwards (to resize) and help with a wedding band was excellent. My wife and I are very happy. Highly recommended.”
“The level of detail and personal service I received was second to none. Scott made the process of designing my wife's engagement ring and our wedding bands so seamless and made the whole experience really enjoyable.”
“Made the difficult decision easy, talked me through the whole process, was transparent with costs and most importantly the end result was amazing!!”
“Great service, communication & quality of product. Scott is great to deal with.”
“Scott from Culet was awesome to deal with. Great communication through the whole process and a ring of excellent quality. We are both very happy!”
“My engagement ring itself speaks volumes for me to highly recommend Culet, it is a magnificent piece of work! But that, coupled with the excellent customer service, professionalism, knowledge and creativity takes it to a whole new level. They went the extra mile to make sure I was totally happy with the design, nothing was too much trouble, an incredible stone was sourced and I couldn’t be happier. Thanks for making all my ring dreams come true!”
