Diamond Cross Pendant in 18kt Yellow Gold

SKU: DP5719

AUD $1,620.00 incl. GST

Some pieces you save for special nights. This one you live in. Our diamond cross pendant sets twelve round brilliant diamonds along a clean cross, each stone placed close to the next so the whole piece reads as one continuous line of light. It is small enough to wear under a collar and bright enough to wear on its own, so it works just as well with a Sunday shirt as it does with an evening dress.

The warmth comes from the gold. We craft this piece in 18kt yellow gold, a richer, deeper gold than the nine carat you see on the high street, and finish it by hand in our Parramatta atelier. The diamonds are F colour and VS clarity, which simply means they read bright and clean to the eye, with no cloudiness. The result is quiet, balanced, and the kind of thing you reach for without thinking.

Because every piece is made in-house, we can shape this one around you. This is the pendant on its own, so you can pair it with a chain you already love or let us help you choose one to suit. Prefer a different gold, or a matching set for someone special? We start a real conversation, not a sales pitch, and build it to suit how you actually wear it.

Features:

  • Diamonds: 12 round brilliant cut diamonds, 0.34ct total, F colour, VS clarity (near-colourless and clean to the eye)
  • Metal: 18kt yellow gold (also available in 18kt white gold and 18kt rose gold on request)
  • Pendant only: Chain not included — pair with your own or ask us to help you choose
  • Handcrafted: Made in-house at the Ernesto Buono atelier, Parramatta

Style Your Diamond Cross Your Way

A cross pendant loves a simple chain, but it also plays well in a layer. Hang it from a fine chain for a clean, classic look, or pair it with a longer chain for something more relaxed. It sits beautifully alongside diamond stud earrings for a matched set, or next to pieces you already own. For more ideas and new arrivals, follow us on Instagram.

Why Choose This Diamond Cross Pendant

First, the gold. 18kt yellow gold holds its warm colour and feels substantial without being heavy. Second, the diamonds. F colour, VS clarity means they read bright and white with no cloudiness, so the cross sparkles even in everyday light. Third, the make. Ernesto sets each stone and finishes each piece himself, so the quality holds up close, not just in photos.

And why Ernesto Buono Fine Jewellery? Because we treat every piece as personal. We sit with you, we listen, and we make jewellery that fits your story. Ready to see it in person? Book an appointment and we will show you how it looks on.

Your Diamond Cross Pendant Questions, Answered

Does this diamond cross pendant include a chain?

No, the pendant is sold on its own, and there is a good reason for that. A chain is personal, so we let you choose the length and style that suits you rather than boxing you into one. The cross has a smooth bail, the little loop at the top, ready to thread onto any fine chain you fancy. So you pick the metal, the drop, and the look. We carry a lovely range of gold chains, and we are always glad to help you match one that hangs this dainty cross just right. That way the finished piece feels truly yours.

Is the smaller size right for me or for a child?

Quite possibly, since this is the daintier version of the design at 0.34ct. Its slim, light profile sits flat and comfy, which makes it lovely for everyday wear and gentle enough for a younger wearer. So it suits a child marking a christening or communion, a teenager wanting her first real diamonds, or an adult who simply prefers understated jewellery. Layering fans love it too, since a smaller cross stacks neatly with other necklaces. Prefer something bolder for a grown wearer? We also make a larger version, and we are happy to show you both side by side.

What do the diamond specs 0.34ct, F colour and VS clarity mean?

Good question, since the lingo trips people up. The 0.34ct is the combined weight of all twelve diamonds on the cross, so think of it as the overall sparkle, kept deliberately delicate here. F colour sits near the very top of the colour scale, so the diamonds look bright and white with no yellow tint, which reads crisp against the gold. VS means very slightly included, so any natural marks inside are so tiny you would struggle to spot them even under magnification. In short, these are high quality, white, clean diamonds in a dainty, wearable piece. Real sparkle, real value, no fuss.

Is a dainty diamond cross pendant a good christening or first communion gift?

It is one of the most treasured choices going, and the smaller size suits these occasions beautifully. A cross marks faith, and a delicate diamond cross adds a gentle sense of occasion that a child can grow up wearing. So it fits a christening, a baptism, a first communion, a confirmation, or simply a heartfelt birthday or Christmas. Because it is light and timeless, it carries from childhood right through to adult life, gathering meaning along the way. Pop it in a beautiful box with a note about the day, and you have given a keepsake that will be cherished for decades.

How do I clean and care for my diamond cross pendant?

Easy, and the kit is already at home. Soak the pendant for ten minutes in warm water with one drop of dishwashing liquid, then gently brush each diamond with a soft toothbrush to lift the film that dulls sparkle, paying attention to the back. Rinse, but pop the plug in first, since small pieces slip down drains fast. Pat dry with a soft cloth. Do this every fortnight, and keep it away from bleach, chlorine, and perfume. Store it flat or hung so the chain does not tangle. Once a year, bring it in for a polish and a quick claw check.
