Vintage Art Deco Diamond Ring Buying Guide

Art Deco diamond rings first became popular in the period between the 1920s and the 1930s. These rings are often eye-catching in their design. Vintage Art Deco diamond rings are available in a wide array of styles, sizes, and metals. With advancements in technology, fashion, and the availability of materials during the Art Deco period, jewellers discovered new ways of working with platinum. So, many Art Deco diamond rings are made of this metal, as well as yellow and white gold. Changes in machinery also allowed for the creation of very precise, detailed, and decorative rings, as well as new diamond cuts, such as the marquise, emerald, and pear.

Art Deco diamond rings are characterised by their bold geometric shapes and large sizes. Square and triangular cut stones were popular in the era as they created strong patterns. Coloured stones became fashionable, especially as accent stones around a larger gemstones. The gemstones were most frequently set in a white gold or platinum band. When purchasing a vintage Art Deco diamond ring, buyers should learn how to rate diamonds by carat, cut, clarity, and colour, consider ring measurements, and familiarise themselves with standard ring sizing. Vintage Art Deco diamond rings can be bought from auction houses and online at retailers such as eBay..

Rating a Vintage Art Deco Diamond Ring

Before purchasing a vintage Art Deco diamond ring,, buyers should familiarise themselves with the diamond's quality by learning how diamonds are rated. Diamonds are rated using a system known as the Four Cs: carat, cut, clarity, and colour. Diamonds that are rated at the top of each of the Four Cs are considered to be the most desirable and expensive, as they are the most rare.

Carat for Vintage Art Deco Diamond Rings

Carat refers to the weight of the diamond. In a diamond, one carat is equivalent to 100 points. So, a diamond of 75 points weighs 0.75 carats. The higher the number of carats, the more expensive the diamond.

Cut for Vintage Art Deco Diamond Rings

Cut refers to the diamond's proportions. Precise angles are extremely important in order to provide the most light reflection. The cut grades are described in the table below.

Cut Grade

Description

Ideal/Excellent

Excellent light performance

Reflects almost all of the light that enters

Rare and extremely beautiful

Very good

Very good light performance

Reflects almost all of the light that enters

Considered to be of an outstanding quality

Good

Good light performance

Reflects most of the light that enters

Far less expensive than very good cuts

Fair

Not as brilliant as a good cut

Considered good quality diamonds

Poor

Typically too shallow or too deep

Causes much of the light to leak out of the diamond's sides and base

In addition to the quality of the cut, the cut of a diamond also refers to its shape and the number of facets. A diamond gets its shape and sparkle through exact cutting and polishing. This allows the diamond's facets to show the most internal and external light. Popular diamond cuts include emerald, heart, princess, marquise, pear, oval, radiant, and round.

Clarity for Vintage Art Deco Diamond Rings

Diamonds typically have tiny marks, referred to as inclusions. Inclusions may be present in the form of a blemish, scratch, air bubble, or any other foreign material, either inside the diamond or on the diamond's surface. Inclusions interfere with the ability of light to pass through the diamond. The number and location of the inclusions are identified under ten times magnification. The diamond is then rated on a six tiered scale, from flawless to imperfect. Flawless diamonds are the most precious as they have the best clarity, while imperfect diamonds have the greatest number of inclusions. Buyers should always bear in mind diamond clarity when searching for a vintage Art Deco diamond ring. The flaws in very slightly included diamonds may not be identifiable to the naked eye. However, these lower quality diamonds should be lower in price than flawless diamonds.

Colour for Vintage Art Deco Diamond Rings

The colour of a diamond generally refers to the presence or absence of a tone in the white diamond. Colour in diamonds is the result of the composition of the stone and does not change over time. A diamond's colour is graded from D, colourless, to Z, light yellow. Grade D diamonds are known for their superior quality. Grades D to F are naturally the most valuable and desirable because of their rarity, while grades G to I show virtually no visible signs of colour to the untrained eye. J to M rated diamonds may show a very faint hint of yellow. However, this hue can often be minimised by mounting the diamond in the right setting.

Measuring for a Vintage Art Deco Ring

Before purchasing a vintage Art Deco diamond ring,, buyers should determine the desired ring size. The ring should fit snugly around the wearer's finger without impeding circulation or falling off. If the ring is not a perfect fit upon purchase, then buyers should consider having it resized by a professional jeweller. Rings with intricate designs or engravings may not be able to be resized without impairing the design. This should be taken into consideration when selecting a ring.

Instead of cutting the ring and soldering it back together, rings can also be resized through stretching. Platinum rings are tough and require a high temperature to enable them to be cut. Therefore, platinum rings or wide rings with a flat band and even thickness may be stretched. In order to avoid stretching the ring metal an excessive amount, rings should not be sized up or down more than two sizes. It may be difficult to match alloys used to make vintage Art Deco diamond rings, so in these situations, stretching is the ideal solution.

In order to find the proper size, wearers should measure around the finger, taking into account the size of the knuckle, which the ring will need to pass over.
