Anniversary Gift Guide: Lab Diamond Jewelry by Year
There’s no rule that says which anniversary needs a diamond — that’s tradition, not a requirement — but once you’ve decided on a lab-grown diamond piece, matching what your partner already wears and getting the made-to-order timing right matter more than which numbered year it is. This guide covers where the “diamond anniversary” idea comes from, how to pick a piece for early, mid, and milestone years, and how to plan the order around the date.
Where the “diamond anniversary” idea comes from
Anniversary gift traditions vary by list and by country, and there’s more than one version in circulation. The classic Western gift list places diamond at the 60th anniversary, alongside silver at the 25th and gold at the 50th. Some modern or updated gift lists move diamond much earlier, often listing it for the 10th anniversary instead.
Neither list is an official rule — think of them as loose cultural shorthand rather than something to follow strictly. The traditional list also assigns a theme to almost every year in between: paper for the 1st, wood for the 5th, tin or aluminum for the 10th, and so on, long before it reaches silver, gold, and diamond. A lab-grown diamond piece is a reasonable gift for any anniversary you want to mark, traditional theme or not — plenty of people simply prefer diamond jewelry to whatever a list assigns to that year.
Picking a piece by milestone year
1st anniversary
A first anniversary tends to suit something modest rather than a statement piece. Devotion, our $99 heart pendant on a fine 925 sterling silver chain, is sized for daily wear and works well as a first-anniversary gift without over-committing on price.
5th anniversary
By five years, a design with a little more presence often feels right. Celeste, our half-eternity band with round brilliants set across the front half, is a reasonable choice for a milestone like this if you already know the ring size.
10th anniversary
The 10th shows up on some modern gift lists as a diamond year, even though the traditional list reserves diamond for the 60th. Either way, a decade is a natural point to consider a larger piece: Infinity, a 1.0ct pendant cut to the hearts-and-arrows pattern, is a full-carat option that doesn’t require knowing a ring size.
25th anniversary
The 25th is traditionally the silver anniversary, which pairs naturally with GemsGlitz pieces, since everything we make is set in 925 sterling silver. Eternal, our 1.0ct six-prong solitaire ring, or Solitaire, our largest pendant stone in a bezel setting, both suit a milestone like this.
50th anniversary
Fifty years is traditionally marked with gold. GemsGlitz doesn’t sell gold or platinum pieces — everything is 925 sterling silver with a rhodium finish — so a lab-grown diamond piece from us leans into the “diamond” side of an anniversary rather than the metal. Luminous, with pavé along its band, paired with Grace on its adjustable chain, works well as a matched gift for a milestone like this.
60th anniversary and beyond
The 60th is the traditional diamond anniversary itself, which makes it a natural year to choose whichever piece feels like the most significant one in the range. Eternal, at a full 1.0ct, is the largest stone among our rings.
Matching what they already wear
The most useful sizing question for jewelry isn’t the anniversary number, it’s what the person already wears day to day. If they already wear rings on the intended finger, a ring gift makes more sense; if they mostly wear necklaces or don’t wear rings at all, a pendant will get more actual wear.
It’s also worth knowing that every GemsGlitz piece is 925 sterling silver with a rhodium finish rather than gold or platinum, so if the rest of their jewelry box is mostly gold, a new silver piece won’t match metal-for-metal, even though it will still read as fine jewelry on its own. See our materials page for more on the metal every piece is set in.
Ring or pendant for an anniversary gift
Rings carry more symbolic weight for an anniversary, but only if the size is right, which usually means finding it out in advance rather than guessing. Pendants sidestep that problem entirely — a chain works regardless of hand size — which makes a pendant the safer choice if the gift needs to be a surprise or you’re not certain of the ring size. See our gift guide by occasion for more on choosing between the two.
Finding a ring size without spoiling the surprise
If a ring is what you want to give and the anniversary is meant to be a surprise, there are a few reasonable ways to find the size without asking directly. Borrow a ring they already wear on the correct finger, even briefly, and have a jeweler measure it or trace the inside circumference yourself. A sibling, close friend, or parent may already know the size or can find out without raising suspicion. Comparing against a ring you already own on the same finger is a rough but workable fallback if their finger is noticeably bigger or smaller than yours.
Sizes vary by ring: Eternal spans US 5–10, Luminous is only offered in US 6–7, and Celeste’s range is listed on its own product page. If you genuinely can’t find out in time, order your best estimate and lean on the return window if it turns out to be wrong.
Budgeting across the years
GemsGlitz pieces run from $99 to $189, and there’s no rule that a later anniversary needs a bigger budget than an earlier one. A first anniversary can reasonably be a $99 pendant and a fiftieth can reasonably be the same, if that’s what suits the couple. Where price does move, it tracks carat weight and design rather than the anniversary number itself — a full 1.0ct piece like Eternal or Infinity costs more than a 0.6ct piece like Radiance Classic simply because there’s more stone involved.
Timing your order around the date
Every piece is made to order rather than held in stock. Expect dispatch within 5–7 business days of ordering, then roughly 10–20 days in transit depending on destination — so for a specific anniversary date, order at least a few weeks ahead rather than the week before. If a ring turns out to be the wrong size, or the piece isn’t quite right, unworn items can be returned within 30 days.
Frequently asked questions
Is diamond really the 60th anniversary gift?
Traditionally, yes — most Western gift lists place diamond at the 60th anniversary, alongside silver at the 25th and gold at the 50th. Some modern or updated lists place diamond earlier, often at the 10th. Neither is an official rule, just a shared convention.
What if the anniversary doesn’t have a diamond theme?
There’s no rule that a lab-grown diamond piece has to match a specific year’s traditional gift. It’s a reasonable choice for any anniversary; the tradition is just a starting point if you want one.
Should I buy a ring or a pendant?
A pendant if you’re not certain of the ring size or the gift needs to be a surprise — it works regardless of hand size. A ring if you already know the size and want something with more symbolic weight.
How far ahead should I order?
At least a few weeks. Pieces are made to order, dispatched in 5–7 business days, then in transit for a further 10–20 days depending on destination.
Do GemsGlitz pieces come in gold?
No. Every piece is 925 sterling silver with a rhodium finish. If the rest of their jewelry is mostly gold, keep in mind a new piece won’t match metal-for-metal.
Whichever year you’re marking, the most reliable approach is to think about what they’ll actually wear rather than which metal or gift a tradition assigns to that number. Browse the full ring collection to compare pieces side by side.
