I found out recently there are way more customers come to ask about diamonds at around 0.7 carat. Many people got one big question in mind. How big is a 0.7 carat diamond actually? If we set it with a setting that make the stone look bigger, can it show the visual effect same as a one carat diamond ring? Almost everyone who know a little about jewelry know this truth. For diamonds with identical color, clarity and cut grades, a 1 carat diamond cost far more expensive than a 0.7 carat one. The main reason is the carat premium in diamond market. Then here come another doubt. Is a 0.7 carat stone much smaller than one full carat in real sight? Let us take a look at a diamond size comparison picture I prepared below.
We can clearly tell from that picture. Under ideal perfect cut standard, a 0.7 carat round brilliant diamond has a surface diameter of 5.8 millimeters. On the other side, a standard 1 carat round diamond reach 6.5 millimeters across its top face. The physical gap between these two sizes is really tiny, almost hard to notice with bare eyes. But if you match your 0.7 carat center stone with a well-designed halo or wide open setting which enlarge the stone visually, the whole ring might even looks larger than an original 1 carat diamond ring when people glance at it casually. Just like full one carat diamonds, most qualified 0.7 carat stones will come with international authoritative certificates such as
GIA report. Every certified diamond has a unique matching GIA certificate number laser engraved on its girdle edge, so buyers can check the stone identity easily later.
Lots of shoppers have shared same experience with me many times. They walk into some local jewelry store and spot a 0.7 carat diamond there. The store used a simple
six-prong mounting for it. Strangely enough, that diamond ring look visibly bigger than the 1 carat rings placed next to it on the display counter. Most buyers will get excited right away when they see such scene. They think they found a super good bargain with huge value. They start wonder should they pay the bill and take the ring home without second thought. Here Ijadiamond give all buyers an important warning, you better stay away from those tricky diamond rings without careful inspection first. Some dishonest merchants use low-quality cut diamonds to cheat ordinary customers, and sell them at high price same as well-cut stones. Those bad-cut 0.7 carat diamonds have an abnormal wide diameter much bigger than official standard data, but their total carat weight still stay fixed at 0.7 carat. To gain a wider table surface, the diamond cutter will make the stone’s pavilion depth extremely shallow. This type of poor cut grade diamond will totally ruin the stone’s light performance and fire. The overall outline of such diamonds just like a flying saucer. People in trade also name them
flying saucer diamonds. Do not rush to make purchase decision in such situation. You will lose more money than you save in the end, and the ring will look dull and lifeless forever.
How much money do people need to spend on a 0.7 carat diamond?
Four C standards are the core factors that control all diamond pricing. The four C items include carat weight, color grade, clarity grade and cut grade. If color, clarity or cut grade shift even slightly, the total price of a 0.7 carat diamond can create a massive price gap between different stones. Right now, people can search for 4,349 perfectly cut round 0.7
carat diamonds on the Blue Nile official website. Their price range fall between 11,000 Hong Kong Dollars and 46,800 Hong Kong Dollars. On James Allen’s online platform, there are around 2,956 ideal cut round 0.7 carat diamonds available for selection. Their price start from 10,200 Hong Kong Dollars up to 45,900 Hong Kong Dollars. Online diamond retailers have much lower running cost compare to offline physical jewelry shops. Physical stores need to cover monthly store rent, employee salary, in-store display maintenance and many other daily overhead expenses. Without those heavy extra cost burdens, online diamond shops can offer much friendlier and cheaper price tags for same quality diamonds to all buyers.
