I agree with Snow♦'s answer and I would also add, make sure to express that you are thankful for the gift (and not just that you are disappointed that it was broken). I'm sure whoever picked it out will be happy to hear that you like it so much you would want a replacement.

I really like the glass bottles that were selected as our gifts this year! I was a little disappointed on opening mine to discover it was broken - are there any extras I could change it for? Thank you!"

HR bought these presents. They paid money for them. They paid good money, and at least one of the presents was broken. Nobody likes to pay money for broken stuff, so HR will want to know about this, and then get a replacement from the vendor.

Tell them about it, so they can go back to the vendor. If not, then make sure that they never find out, because they will be annoyed if they find out later they paid good money for broken presents and were not given the chance to fix it.

There is a small chance HR will think you broke the bottle, that's the only potential downfall I can see. If you're worried that this may affect your reputation within the company then perhaps it's not worth asking for a new bottle.

However, if you explain honestly your version of events then I'm sure they'll replace it. I'd ask for a replacement if they have a spare, do not ask them to send it back to the manufacturer:

"I was so grateful to receive this gift but when I opened it I discovered it was broken. I guess it was a manaufacturing defect or
maybe it got broken in transit. If there's any spare bottles do you
think I could swap mine please?"

I don't see any answers yet that quite capture the approach I would take to this.

I think the only danger to avoid is being seen as a "problem employee" if you seem ungrateful for what they gave you, so make it clear that you appreciate that the company was willing to buy you the gift. A company has no obligation to give gifts (at least in the U.S.), so they are already acting generously. But if you are as thoughtful and polite as you have been here, I don't think you have anything to worry about.

I agree with others that the company wants to show appreciation and did not intend to give you a defective gift, so they'd want to replace it to make sure you don't feel snubbed (even if only because a disgruntled employee is bad for morale). So it is worth bringing up with HR.

(As an aside, it may be that other employees also received defective bottles, yet the company may not be aware of the issue. And if the fault was with the supplier as you suggest, they may even replace it at no cost to your company. I don't think that changes your approach, but maybe helps to convince you that it's worth bringing it up.)

I would try to be as polite as possible and avoid making a big deal out of it. Ask if they happen to have an extra bottle or if it they'd be willing to get a replacement for you, but don't push the issue if they say no. It was free to you, after all, so you do not have any right or entitlement to it.

So you might say:

I'm so glad that the company gave us these lovely bottles! They are a very nice gift! But I am a little sad that mine appears to be defective. Is there any chance that there is an extra one left over, or that the supplier might replace it for us? If not, don't worry about it, but I'd be very happy if there is, because I really like the bottle.

If they are willing to take the extra steps to replace the bottle for you, then I would also consider sending a thank-you note or some other extra token of appreciation to show your gratitude.

Of course, I'm American and don't know much about Indian etiquette (assuming you are in India as your reference to Diwali suggests), so take my advice with a grain of salt and use your own discretion as to how you expect them to handle it.

I would leave it as it is and just move on.

As they did not do that on purpose and it's just a simple gift, so why bother anyone replacing them? Probably HR would have to contact this company to do replacement or so, it just not worth it I guess. I am pretty sure you will get many gifts in your life you will enjoy way more!

There was a similar incident in our office on Diwali occasion, We received personalized silver coins as a Diwali gift. One of the employee noticed that his coin was smaller and weighed less. So, he just requested our manager of the incident and manager quickly reported Issue to concerned person and his replacement was in an instant.

You should take a similar approach and report this to your direct manager. Mostly when ordering these gifts 2/3 extra items are ordered in case there are any defects in any of them so they can be quickly replaced.
