Grandma’s Vintage Diamonds vs. New Diamonds, How to Design With Them

“I have seven pieces of inherited jewelry from my Grandma Lolly that I never wear,” Pat said to me one day. “My challenge to you is to design a brand new custom piece of jewelry using all of the old diamonds from my Grandma.”

Is there a trick to designing with older cuts of diamonds? You bet. Read on for Pat’s story and the seven rules for working with older diamonds.

 

Pat’s Jewelry Loving Grandma Lolly

The challenge to this project was that though most of the diamonds were of older cut styles, three of her diamonds were modern cuts from replacements of lost diamonds. The replacements stood out like tree ferns on the moon.

Vintage Diamonds or New Diamonds, They Are All Lovable

When you compare an older cut vintage diamond to a diamond with a modern cut, it is easy to see the difference.

Different doesn’t mean bad, it just means different.

Things can go bad, however, when you try to combine the two different diamond cuts into a single piece of jewelry next to each other without careful planning.

The new modern brilliant cut diamond will have a sparkle and fire that the older European cut diamond or old mine cut diamond just can’t match.

Therefore when designing with older cut diamonds there are some design rules, which I would like to share with you.

Hand Faceting Years Ago VS. Modern Cutting Technology

Even Very Old Diamonds Still Sparkle!

Before we get to the rules, I want to give you a little bit of information about antique and vintage diamonds.

In the past, diamond cutters used techniques to cut diamonds that are no longer used today. They cut with the priority of enhancing the color or lack of it. Modern whiter diamonds have allowed cutters to focus on sparkly brilliance in their cutting.

In the past, diamond cutters cut diamonds by hand, and created diamond shapes and dimensions that reflected the era in which the stone was cut. Time and technology have given diamond cutters the skills and resources that just weren’t available a hundred years ago.

Diamonds that were cut by hand exhibited less fire and brilliance than diamonds that are cut in the modern way today. Happily for vintage diamonds, many people prefer the warmer, romantic glow that comes from a diamond cut by hand.

In fact, antique and vintage diamonds are starting to become quite a popular trend again. More brides-to-be are deciding to go with the old-fashioned romance of an antique or vintage cut diamond as their gemstone of choice.

The Difference Between Vintage and Antique Diamonds and Modern Diamonds

Many antique and vintage cut diamonds are of lower color than what would be considered “top” color today. This is because the mines that yield such colorless beauties that we see today were undiscovered all those years ago.

However, the unique cutting techniques and facet arrangements used on antique and vintage diamonds, often fool the eye into believing the actual color of the stone is much higher than it is. This is especially true when the older cut diamond is set into a mounting.

One of the most unique factors of an antique or vintage cut diamond, is that the faceting arrangement creates a much more chunky facet look. You’ll also see a more colorful play of light with the older cuts as well.

Modern cut diamonds show a brighter fire with more tiny pin point flashes of light. It’s as if they are charged up with energy. The older cut style is beautiful in a more mellow way.

Seven Rules For Designing With Older Cut Diamonds

Old Style Cushion Cut Diamond

    1. Do not mix modern cut diamonds with older style cuts of vintage diamonds. (Subtle sparkle vs. focused and flashing sparkle.)
    2. Chose designs with vintage details to accent the charm of your older cut vintage diamonds. (Details like filigree, decorative hand engraving and fancy detail around center diamond.)

3. Use textured details like milgrain edging to enhance older diamond beauty. The texture of milgrain edging enhances the impression of sparkle in your diamonds. (See my blog post on milgrain engraving.)

4. If your older diamonds exhibit slight off color details, try setting them in yellow gold or rose gold. (Yellow gold is better for slight yellow tones, rose gold is better for brown and grey tones.)

5. If your older cut diamonds have visible inclusions, set them into a group of diamonds off to the side, or if they are sentimental to you, consider setting them into the gallery work, (side view under crown element), where they will be most visible to you alone. Keep in mind that the optical illusion of the better diamonds nearby will fool the eye to forgive the more imperfect one.

This Would be a Great Way to Use Older Less Sparkly Diamonds

6. Older cut diamonds frequently don’t hold their sparkle when they get dirty. Modern cuts often continue to shine when dirty. It is often recommended to use the older cuts in earrings or pendants instead of rings. (Rings tend to get dirty easily unlike earrings and pendants.)

 

Those Diamonds Look Awful Together. No Thanks!

7. Find a jeweler who works with vintage jewelry or is an experienced jewelry designer and knows about the various eras of diamonds. Walk away from a jeweler who doesn’t offer matching older cut vintage diamonds and tries to sell you on using modern cut diamonds with your old ones saying, “Oh, it’ll look just fine.” (It won’t!)

Pat’s Old Diamond Design Desires

A week later, Pat and I sat down at her kitchen table with her grandma’s five ring and two pendants. I could immediately see that many of the diamonds were single cut—an older style with fewer facets.

The sizes and colors of the diamonds also varied widely. Fortunately, the largest diamond rated the best of the lot. Unfortunately, it had a few small chips on the sides.

“Grandma Lolly was my favorite and I’ll always love her,” Pat said. “She managed to take me on lots of adventures when I was young. What I really want is to somehow use all her diamonds in one piece of jewelry.” I pulled out my pad and pencil and we got down to work.

Pat’s Design Wishes Translate into the Basic Shape

Pat wanted a heart shape to represent her love for her Grandma. We began with that.

Since there were a lot of diamonds there was no way that we could do a ring unless it was huge and kind of gaudy.

However we could totally make it as a pendant.

Problem Solving For a Chipped Diamond

An Antique Cut Diamond Like This Can Have Chips Hidden by a Bezel

Since the large, center diamond was chipped in multiple places on the sides, I suggested we bezel set it to cover up the imperfections.

Pat agreed. She didn’t want to re-cut the diamond. She kind of liked the personality of those chips.

She liked the idea of knowing they would be hiding there under the bezel setting.

After several different configurations, we finally settled on placing the largest diamond in the center of the heart. Pat had a mixture of single cut small diamonds and Old Mine Cut medium cut diamonds.

Dealing With Different Sizes and Colors of Diamonds

We Jewelers Unkindly Call These Diamonds, Frozen Spit and Brownies. Maybe Don’t Re-Use These

Since the diamonds were different sizes, we chose to arrange them from biggest nearest to the center to smallest radiating outward. We used the tiny modern cut diamonds down low and too the side where they didn’t make the other diamonds look bad.

I suggested we place some of the more “off color” diamonds on the outer edge where the design curved down, where they’d be less visible. Pat liked that idea.

“I also think pave setting would be the way to go,” I said to her. “For setting the smaller diamonds.”

“Pave?”

“Pave is a style of setting that would allow us to set the diamonds close to each other and capture the curvy puffed nature of the design we’re looking for. After we cast the basic shape, the setter will create the tiny prongs to hold the diamonds. This allows the setter to accommodate different size gems. It’s like he’s putting together a puzzle.”

The Happiness of Your New Piece of Redesigned

Four weeks later I presented Pat with her finished heart pendant. “Oh my God!” she exclaimed with tears running down her cheeks. Admittedly, my eyes weren’t completely dry either. It was such a happy moment.

Pat gets many opportunities to tell stories about her grandmother when people ask about her pendant. Pat told me, “Calla, I’m so glad I re-used Grandma’s diamonds. I love my necklace!”

Calla, I have come to expect great advice from you in your blogs. This information on designing with older diamonds is great.
Having seen rings that have newer replacement diamonds next to older vintage diamonds and seeing the clash of shine and sparkle, I agree that there have to be rules!
Calla Gold your vintage diamond design rules are excellent!
